The ventilating valve for a steam room. How to make ventilation in the sauna: scheme options, device and materials. The way "from the grandfather"

To the question of what a bath should be, any person will answer the same way: hot and “light”. This is an obvious fact for everyone. Therefore, the majority approaches the process of insulation with all responsibility, using all kinds of methods and materials to ensure maximum heat retention inside. It is not surprising that this creates the effect of a thermos.

They don’t provide the second component of an excellent bath, they miss it and wonder why the “steam” failed, and instead of a healing effect, the opposite result was obtained. Unfortunately, even experienced people forget about such an important point as.

But its significance should not be overestimated: during the heating of the furnace, oxygen burns out, and instead of it, CO2 is released, under the influence of which high chance of "burning out". Our blood is supersaturated with carbon monoxide, there is a possibility of disorientation or loss of consciousness (not to mention the more unfortunate consequences). Therefore, a system is needed that provides oxygen supply and additionally regulates the temperature regime inside the steam room.

In addition to the functions of replenishing oxygen, ventilation allows you to dry the building, stopping the negative effects of excess moisture and steam, which can lead to the appearance of mold or rot on the structures, as well as an unpleasant smell or musty feeling. Lack of exhaust can destroy wood in just 2-3 seasons.

A ventilation device is required in any baths, not only brick and block ones, wooden ones are no less demanding for drying. An exception may be baths with slots, but here they cannot be called baths: they will not retain heat.

REFERENCE. Of particular note is the possibility of using natural ventilation, which does not require the use of expensive materials and equipment (however, it is also not worth leaving a gap on purpose). How to organize this process we will tell in this article. We will not ignore the device of the forced supply and exhaust system.

Ventilation in the bath in the steam room: why is it necessary?

Above, we have already talked about the dangers of a closed environment from the point of view of carbon monoxide exposure, and also mentioned the need to create a microclimate for drying the steam room after its use. Ventilation in the bath, in the steam room will definitely increase the comfort of staying there and extend the life of the building.

A distinctive feature of the Russian bath is wet steam. At the same time, the temperature regime also varies, which is lower than that of the sauna. However, warm air saturated with moisture warms up the human body much faster and has a softer and more gentle effect (there is no spasmodic effect on blood vessels, you can visit the elderly and children).

The device of the furnace is quite specific: as a rule, stones are placed inside, access to them can be obtained by opening the door. This ensures that the stones retain heat for a longer time, and they are more difficult to pour, even with inept water consumption.

Ventilation in the steam room of the Russian bath. The most important thing is to keep the balance, because the steam has a “shocking” character, escaping from the stove immediately after water has been splashed on the heater. If it is not designed correctly, then you can miss all the steam.

In the Russian steam room, vents are most often used, which are installed at the bottom of the walls and ensure the safety of the heat that accumulates near the ceiling.

Ventilation in the steam room: requirements

When ventilation is designed in a steam room, the requirements for it are simple. You must adhere to the following rules:

coolness should be near the floor, and heat near the ceiling;
even temperature level, without fluctuations;
The “exhausted” air must be replaced with fresh, enriched oxygen.

Ventilation in the steam room: device

It is based on the laws of physics: the influx of fresh air from below displaces hot air from above through the corresponding holes, thereby ensuring air exchange. In this case, a rarefaction of air occurs (pressure decreases), and cool air is drawn in. It, in turn, gradually heats up, rushes up, and further along the cycle. This is how ventilation works in a steam room, its device is quite simple. More .

Natural or forced?

In order to answer the question: natural or forced ventilation for a steam room - it should be disassembled in each of the types.

Natural the microclimate is formed independently in the presence of planned vents (openings), or slots, when the air convection processes described above start in the building.

The advantages include: low cost of implementation, the absence of extraneous noise / vibration from working devices and the use of natural features. Possible difficulties: errors in the placement of holes, as a result: lack of traction (the opposite - the appearance of excessive drafts); the penetration of extraneous (with a high degree of probability - unpleasant) odors from the street.

Forced ventilation system uses equipment and materials that create artificial air movement in the required direction. Regulated by special control units. This is a very expensive solution that requires competent design and further implementation. When properly placed, it is guaranteed to provide a measured circulation of air currents.

There are combined types for a bath: steam room ventilation, combining both of these areas and having the pros and cons of each option.

If you decide to do ventilation on your own, but it’s better to stop at natural ventilation - it is more in line with the spirit of the bath than the use of intricate devices. However, we do not dissuade you from using forced supply and exhaust ventilation.

Ventilation in the steam room of the bath: scheme

Ventilation in the steam room of the bath - system diagram. It consists of two openings: one of which is inlet, and the other is exhaust (you can make several exits). When choosing the size of the exhaust opening, you must be guided by several rules:

the largest should be at the maximum distance from the furnace(so that the heat does not go outside in a forward flow);
the rest can be launched around the perimeter of the ceiling;
the size of the holes is calculated based on 24 square meters. cm per cubic meter of room. Most often, the diameter does not exceed 30 cm, but the number is 2 or more.

The traction force is determined by the height difference between the supply and exhaust openings.

IMPORTANT! Do not place the holes exactly opposite each other, this will inevitably cause drafts.

Ventilation in the steam room of the Russian bath: scheme

Ventilation is provided in the steam room of the Russian bath by a scheme in which there are vents with adjustable plugs, taking into account the above rules. Or the use of salvo ventilation, which we will discuss later.

Bath: ventilation of the steam room (if the oven is in the dressing room or rest room)

About the bath, ventilation of the steam room, in which the stove is located in a different room than the steam room, you will most likely have to think about forced ventilation, which will ensure the flow in the right direction.

As shown in the diagram:

Sauna: ventilation of the steam room (if the oven is in the steam room or the steam room is connected to the washing room)

It is provided by heating the cold air coming from the outside from the furnace and pushing it away from the heat source, and returning it back after hitting the walls. Air movement can be stimulated by the use of additional fans.

For a bath, ventilation of a steam room - the organization of drying a bath is especially important, since the water in the washing room can have a truly destructive effect on finishing materials and floors. In addition to the main one, enhanced floor ventilation is required: by installing an exhaust opening between the finishing and subfloor, the installation can be accompanied by the installation of a fan.

REFERENCE. Make sure that the fan does not get water in order to eliminate the risk of a short circuit.

More than 10 different bath ventilation schemes.

Where to place supply and exhaust openings

There are a few simple rules - where to place the supply and exhaust openings:

the supply air (from which freshness comes) should be located below, closer to the floor;
exhaust - located away from the stove, closer to the ceiling.

Wherein it is desirable to place the supply opening near the furnace so that in the cold season the air warms up a little before entering the steam room.

The height at which the holes are placed is about 30 centimeters: from the floor or ceiling.

Will be effective installation of supply valves in the foundation (under the floor). The use of a valve system or the installation of an additional protective grille on the opening will protect you from the possible penetration of rodents. In this case, it is better to lay the floor with small gaps for freer access of oxygen. If you want a smooth and even floor, then you can get by with special ventilation windows that can be covered with decorative wooden gratings.

IMPORTANT! When placing the valve on the foundation, it is necessary to ensure that freshness is taken from the street, and not from the underground, otherwise unpleasant odors will come along with the air.

Common layouts include:

for baths with continuous oven: the inlet opposite the stove is 30 centimeters from the floor, and the furnace blower will play the role of an exhaust hood;
for baths with poured floors: air inlet 30 cm from the floor behind the firebox, and “working out” leaves after cooling through the cracks in the floor;
the location of both holes on the same wall: opposite the stove, but one is near the floor, and the second is near the ceiling. A fan is installed at the exit. Justified where the wall with holes faces the street.
hole arrangement at the same height but on opposite walls(do not output in one line!), The fan is installed in the same way. It is considered not very effective, since the heat will go outside almost immediately, and the drying of the room will be faster due to the open door.

Wall ventilation in a steam frame bath

Frame wall pie. See more about the insulation of frame walls.

It is carried out by leaving a ventilated gap between the finishing materials and the vapor barrier, it can reach 5 cm. The ventilation of the walls in the steam frame bath is provided by a counter grill. The corrugations of the ventilation system should be designed in advance in order to place the insulation with the calculation of the place for the pipes.

What can not be used for ventilation in the steam room?

Refuse to use plastic elements:

corrugation;
boxes;
plugs.

This is something that cannot be used for ventilation in the steam room - they do not withstand high temperatures, they will melt, releasing harmful substances and acquiring an unaesthetic appearance.

But in the washing room or dressing room, their use is not forbidden.

Only wood can be used as plugs for vents or hatches: metal can burn from heat or rust from moisture.

Economy solution: volley ventilation in a Russian steam room

If you are not sure that you can correctly calculate the size of the entrances (exits) or their location, you can use the long-tried method - an economy solution: volley ventilation in a Russian steam bath.

The essence of its application is to quickly ventilate by opening windows and doors wide open. They are plowed open for a short time (no more than 1-2 minutes), for maximum effect it is best to use the opposite window and door.

This method does not require any financial costs: you use the elements that are in any bath.

IMPORTANT! Do not overdo it with ventilation, you can chill the bath a lot. This method is especially good for Russian baths, which are heated in black.

Do I need to hire specialists for calculation and design

If you want a proper, “easy” and hassle-free sauna, steam room ventilation plays an important role: from the longevity of the sauna to your own safety.

If a the bath room is combined with the house, has a rest room or dressing room into which the stove is brought out, or there are other reasons for using forced exhaust, then the answer to the question “do I need to hire specialists for calculation and design” will be unambiguous: it is necessary.

Otherwise, you can make a mistake in an insignificant detail, and the purchased calculation equipment for this reason will not work. And this, in turn, will cause additional costs.

In addition, in order not to violate the structure of the structure, it is better to design the ventilation of the steam room in advance, before the bath is erected, especially when the air inlet must be located on the foundation. Installing a ventilation system in an already built building is a troublesome and time-consuming process. It will require disassembly of almost all finishing materials, freeing up space for corrugations and so on.

When building a brick bath, you can’t do without preliminary preparation at all, because not only wooden finishing materials are required, but also wall material - brick, which (some types, for example, silicate) is prone to absorbing large amounts of water.

Conclusion

Ventilation and renewal of the internal climate are in any case necessary - this is the final conclusion, it is necessary, among other things, to ensure comfort when using the bath. The choice of natural or forced is up to you. We hope that, taking into account our material, you will be able to find the most suitable solution for yourself.

Article in sections:

It can be made according to different schemes, but there is no doubt that this structure cannot be dispensed with without it.

The presence of ventilation in the bath depends not only on the correct distribution of heat in the room, but also on the safety of visitors, as well as longevity services of a wooden bath building. In a bath, especially in a steam room, there is always a large amount of water and steam, and wooden surfaces absorb moisture, and periodic drying of the room is simply necessary. However, it will not be effective enough if constant ventilation is not organized in the premises, which significantly reduces the effect of moisture absorption by wood, since the air is in continuous movement.

The principle of operation of ventilation in the bath

The operation of the ventilation system is based on the known laws of physics, and the principle of its arrangement is quite simple and understandable.

In the bathhouse, two ventilation windows are arranged, one of which provides fresh air, and the second allows hot and waterlogged air to exit.
From the exact location of the ventilation windows will depend on which area of the room the heated air will flow more intensively, which moves under the pressure of the heavier cold air coming from outside. Therefore, sometimes two outlets are arranged instead of one - this is done in order to be able to direct the flow in the right direction by opening one of them or both at the same time by a certain amount.

Thus, a very important factor is the size of the windows, as well as the ability to adjust the clearance they open. To do this, they install gate valves, which can be completely covered or left open a small gap.

Another important task is the correct calculation of the total size of the ventilation window, taking into account the area of a particular room.

- If you install too large openings, the steam room will either never be able to heat up to the desired temperature, or this will lead to excessive consumption of fuel or energy, or in order to achieve the required temperature, it will take a long time to adjust the distance to which you need to open each of the ventilation windows.

- If the ventilation windows are not large enough, the intensity of air movement will be noticeably reduced, which means that the room may overheat or oversaturate the air with moisture.

So, the soft intake, uniform mixing and removal of air from the room will depend on the size of the ventilation openings, their location and the equipment of the system with additional adjustment elements. That is, it is necessary to provide for all these parameters so that there are no sharp thermal drops in the room for individual parts of the body of a person washing in the bath, for example, when cold air blows from the street down the legs, and at the same time the head is under the influence of very high temperatures.

In any case, there will be a difference in air flow temperatures, and this is normal, but visitors should not feel any discomfort from this. Therefore, the air must be mixed as evenly as possible - this depends on the correct scheme of the ventilation system.

Important nuances of planning the ventilation system in the bath

Before proceeding with the choice of a ventilation system and the most suitable design, you need to understand some of the nuances that apply when installing any of them:

The ventilation system is laid in the process - the necessary channels are laid and openings are made into which they are embedded or connected. Directly adjustable windows themselves are installed after the decorative sheathing of the room.

For, to to carry out these works without problems, it is necessary to include ventilation in the bath project in order to carry out all further construction work based on it.

Ventilation openings, ideally, should be the same size. If it is necessary to accelerate the outflow of exhaust air, then the exhaust hole is made a little larger than the inlet, but for safety reasons, in any case, it is forbidden to make it smaller than the latter. Sometimes, as mentioned above, instead of one, two exhaust windows are arranged, not only to adjust the distribution of flows, but also to ensure safety.
Ventilation windows must necessarily have doors or shutters. It is preferable to install the latter, as they close more tightly, leaving no gaps.

During the initial heating of the steam room, the gate valves are completely closed until the required temperature is reached.
Adjustable dampers are also necessary because the flow of cold air depends on the season. So, at a negative winter temperature, cold enters a warm room more intensively. Therefore, during this period, the ventilation windows do not open completely, holding back the flow of cold.
The cross-sectional area of the ventilation window is calculated based on the volume of the bath room. There is a norm that for its one cubic meter a window area of 24 square meters is required. cm.

With incorrect calculations, with deviations in one direction or the other, the room will not be sufficiently ventilated or vice versa, it will be too cold.
Ventilation windows are never located opposite each other and at the same level, since hot air will not have normal circulation and will not cover all the necessary heating areas. Its uniform mixing will not occur, so you need to carefully calculate the correct placement of the ventilation elements.
The windows for the hood are always located at a height slightly below the ceiling, because the superheated air mass rises up. If an exit is provided for it, it rushes into the exhaust opening, which contributes to the timely cleaning of the air in the room. Only under these conditions will the bath house be beneficial, and a favorable and healing atmosphere can be created in it.

Types of ventilation

In different cases, depending on the design of the building and the total volume of the bath room, one of the types of ventilation is arranged.

natural ventilation

This type of ventilation system is based on the difference in temperature and pressure in the street and indoors. The effectiveness of such ventilation is achieved by the correct placement of the inlet and outlet windows. So, the entrance for external air is located next to, at a height of 250 ÷ 350 mm from the floor, and exhaust windows are usually on the opposite wall of the room, 150 ÷ 250 mm below the ceiling.

It is believed that this option is not particularly suitable for a steam room, since the hottest place in this room is its upper area, and the coldest is the floor. It is quite difficult to set up natural ventilation in such conditions, but if you arrange its elements correctly, then even with this distribution of air flows, you can achieve the desired effect.

Forced ventilation

There are special electronic systems for saunas and Russian steam baths, which are trusted to control the temperature and air flow.

The control panel sets the desired temperature and humidity level, which must be maintained in the room, creating a comfortable atmosphere in the bath. Such systems are carried out and connected by specialists, and such services are quite expensive.

Another option for forced ventilation is simpler in design and more affordable. This method of bath ventilation can be called the most widespread, as it will create the right atmosphere, regardless of the weather conditions "overboard".

In this system, in addition to properly located ventilation windows, a device such as an exhaust fan will be needed. The combined version is especially good for baths located inside the house, where ventilation windows are not built into the outer wall, but a long ventilation duct is laid to them from it. In this case, the fan provides the required amount of air inflow and outflow.

The duct exhaust fan must comply with the special conditions of the "bath" operation

It should be noted that special fans are purchased for the bath, which have reinforced waterproofing of the elements of the electrical circuit and the mechanical part. In addition, such devices must withstand high temperatures without losing performance. The working diameter and power of the device are selected depending on the volume of the room.

The required type of ventilation is selected individually for different rooms and types of baths, so when choosing a scheme, you need to carefully think through and calculate everything. Very often it makes sense to provide a combined scheme that combines both the natural circulation of air flows and the possibility, if necessary, to resort to forced circulation.

Video: basic principles and schemes of bath ventilation

Common bath ventilation schemes

The presented diagrams show different options for the relative position of the heater and shelves in the steam room, and the distribution of supply, hot and mixed air flows advising them.

First scheme ( a)

The most used ventilation scheme in the bath is when the window for incoming air is located next to the stove, at a height of 250 ÷ 350 mm from the floor.

During the heating of the stove, cold heavy air coming from the ventilation window moves a light hot stream to the opposite wall, lifting it up to the exhaust opening, which is located at a distance of 150 ÷ 250 cm from the ceiling.

Going all the way, from the lower window to the upper, hot and mixed flows cover the entire room, warming the area of the upper shelf located under the exhaust window as much as possible. If there is insufficient air movement, a fan is installed in the upper vent.

A regulator in the form of movable shutters can be built into the inlet, which will help both regulate the intensity of the intake of fresh air and, to a certain extent, set the direction of the flow in the right direction.

The second scheme ( b)

Natural intensive blowing is carried out through the lower window, arranged on the opposite wall from the furnace. The movement of air in this case is directed towards the heating device, where the hot flow emanating from it is picked up, rises and rushes to the exhaust hole along a wide arc covering the entire volume of the room.

This scheme is well suited for placing a bath, arranged in a house, and having one external wall. In order not to stretch the ventilation duct to the opposite side of the bath, both windows are installed in the wall facing the street.

The third scheme ( in)

This scheme is suitable for a bath with a leak. The air intake window is located exactly in the same place as in the first scheme, near the stove-heater. The output is organized a little differently.

The air, after warming up the upper area of the steam room, goes down, passes through the slots of the flooring, thereby helping to evaporate the moisture that has collected there, which significantly extends the life of the wooden floor.

The exhaust vent is located in an adjacent room or in an isolated channel that no longer has access to the steam room. It is usually equipped with a fan to ensure stable air circulation along such a complex trajectory.

The scheme cannot be called very popular - it is used infrequently because of its complexity in accurate calculations of the location of the ventilation windows, a rather laborious device with the movement of air flows in its cavity. However, it should be borne in mind that it is very effective, and contributes to the most uniform heating of the steam room and, at the same time, helps to quickly evaporate moisture from the wooden floor structures and dry them out.

The fourth scheme ( G)

The fourth option is designed for a constantly working furnace - only in this case, its blower hole will act as an exhaust hood. The inlet window is located under the shelf installed on the opposite wall from the furnace, at the level of its blower.

Cold air is directed towards the furnace and raises the air heated by it to the ceiling. Cooling down, the air masses are forced down and go into the blower hole.

There are also more complex schemes in which there are two supply and two exhaust ventilation windows with forced air circulation. Such a scheme requires careful adjustment, but allows you to set the required temperature in the room as accurately as possible.

As mentioned above, the ideal option would be to install the ventilation system simultaneously with the construction of the bath. In the event that an already finished room is being converted into a bath, or its arrangement is being made, it is best to choose a room or separate a corner that has two external walls. In this case, there will be no problems with the device of the ventilation system.

If this is not possible and the bath is located in the middle of a private house, then there are two options for ventilating the room - to install a ventilation duct that will connect the room to the street, or to bring the ventilation pipe through the ceiling and roof. In this case, the pipe must be closed from above with a protective umbrella, in order to prevent precipitation and fallen leaves from entering the ventilation ducts.

Video: an example of self-arranging bath ventilation

Bath procedures are not only one of the good ways to maintain hygiene, but also an opportunity to remove accumulated harmful substances and toxins from the body. However, in order for the visit to be comfortable and beneficial, a good one is needed to exclude the possibility of the formation of fungi and mold due to high humidity. Ventilation in the bath, equipped by specialists or with your own hands, will ensure the flow of fresh air into the room and remove exhaust gases and fumes resulting from the operation of the heater and the use of hot water.

Read in the article

Do you really need ventilation in the bath or can you do without it?

The functions of bath ventilation are complicated by the fact that it should contribute to a fairly rapid removal of moist air from the premises and qualitatively regulate the temperature in the steam room. It is especially important to have a good exhaust system for baths equipped with gas and solid fuels - to maintain the combustion process in such structures, an influx of an impressive amount of air is required. Lack of ventilation will lead to excessive concentration of carbon dioxide, which adversely affects the health of people and which can lead to loss of consciousness.

Inexperienced craftsmen try to carefully isolate the premises, sealing up the slightest gaps to increase the speed of heating the steam room and keep the heat longer. However, this is the wrong approach, since ventilation holes must be mandatory. Properly arranged allows you to:

create a healthy microclimate in the bath;
reduce the concentration of humidity and quickly drain the premises;
get rid of carbon dioxide;
quickly warm up the steam room and other bath rooms;
eliminate stagnant and unpleasant odors;
get rid of pathogenic fungi and mold;
keep the interior decoration in its original form.

From the foregoing, it becomes clear how important the device is in the exhaust system bath. Before you make ventilation in the bath, you must first learn about its varieties and basic installation schemes.

Effective ventilation in the bath - scheme and device

Before you further deal with the exhaust system and proceed with its arrangement, you should know that ventilation can be natural and forced. There are also differences in ventilation systems and their schemes depending on the location. Well, now about everything in order.

natural ventilation

This option is optimal for most baths, as it is the cheapest and quite effective. The location of the ventilation openings must be determined based on the size of the room, the location of the heater and shelves, as well as the material from which the sauna is built. Whatever the ventilation schemes in the baths, there is one general rule - the inlet should be located at a height of 20-30 cm from the floor level, and the exhaust at the same distance, but from the ceiling.

The dimensions of the vents should be approximately 300-400 mm 2. If the air exchange is too fast, which will cause a decrease in the temperature in the steam room, the ventilation openings must be covered with special control dampers. To improve the appearance, it is desirable to mount decorative grilles on the vents, which can be easily bought in specialized stores or made by hand.

However, this type of ventilation is not suitable for a steam room. All ventilation openings (inlet and outlet) must be at the same level from the floor. Thus, the incoming air streams are heated from the furnace and rise up, while the cooled air flows down and enter the exhaust vents. To keep the heat in the room, the openings can be closed with special dampers.

Forced ventilation

Mechanical movement of air is carried out by installing special devices on the ventilation openings (). This will allow you to quickly update the air, which is very important, especially in the washing room. This ventilation option is well suited in cases where it is installed in the bath. The forced exhaust scheme in the bath has a number of advantages over the natural one:

it is possible to filter incoming air masses;
maintaining a given microclimate;
even distribution of heated air.

For large volumes of fresh air to enter the steam room, it is necessary that the ventilation openings are located diametrically to each other. During installation, it is not necessary to place the inlet and exhaust vents at the same level in order to exclude the closure of air flows, which will cause a concentration of cooled air below, and on the contrary, it will be very hot at the top.

Important! Since high humidity and high temperature are the main enemies of any electrical equipment, the fan case must have reliable moisture protection, and the connection must be made in full accordance with the PUE.

The advantage of forced-type ventilation is accelerated air exchange and advanced adjustment options. Such an exhaust system is equally effective regardless of the strength and direction of the wind, as well as weather conditions.

The device in the baths of floor ventilation

The floors in the bath rooms are operated in extreme conditions. The impact of moisture on the floor is carried out both from below from the side of the soil, and from above. The most difficult conditions are created in the steam room, where hot steam comes into contact with the wooden flooring, cooling and condensing. The resulting condensate penetrates into and creates a favorable environment for the development of fungus and mold.

An effective floor ventilation scheme helps prevent the damaging effects of mold and remove excess steam. Floor ventilation can be natural or forced. However, for efficiency when installing a ventilation system, the following conditions must be observed:

prevent floor cooling during the adoption of procedures;
ensure fast and efficient drying, but it is important not to overdo it in order to prevent cracking of the wood;
the arrangement of the ventilation system is required to be carried out at the construction stage.

When arranging ventilation vents, it is necessary to take into account the climate, wind conditions, landscape, sources of pollution, as well as internal factors - the type and location of the heater, the design of doorways, the presence of vents. Most often, vents for ventilation are located at 3 different levels:

under the floor covering or in;
under the heating structure or at the level of its foundation;
in the wall at a distance of 350-450 mm. from the floor level (best done behind the heater).

The device in the ventilation baths under the floors has a number of advantages. In addition to eliminating condensate and improving the quality of drying the floor covering, the air flow from below does not form drafts and, therefore, ventilation can also be used in the process of taking bath procedures. For greater efficiency, it is important to correctly create a drain system to remove drains outside the building.

Creating air exchange in the foundation of the bath

The creation of an exhaust system in the bath is extremely necessary, as it not only helps to prevent the formation of mold, but also to protect the building from rot. The characteristics of the ventilation system are calculated at the design stage. The type and location of bath ventilation largely depends on the prevailing winds, topography and the presence of water bodies, which often cause buildings to flood.

It is possible to ensure normal air circulation by arranging several holes, the number and size of which are calculated in accordance with the size of the bath. The diameter of the vents must be at least 110 mm. Ventilation openings are usually made opposite each other. In the event that the building is located in a lowland, densely surrounded by other buildings, or there are natural barriers to the free movement of air flows, then vents must be arranged on all sides of the foundation, since this is the only way to achieve high-quality ventilation.

The ventilation system in the baths in the steam rooms

Traditionally, a stove-heater is installed in the steam room, which forms the basis. The air from the steam room passes through the blower, which ensures its good circulation. To obtain the maximum outflow of air masses, the stove should be installed below the level of the finished floor, and to start the ventilation process of the room, it is enough to slightly open the window or the front door. The disadvantage of such a ventilation scheme in the steam rooms of the baths is that when there is no combustion process, the air circulation stops.

In addition to the heater, ventilation in the steam room is provided by additional openings with special dampers to regulate air exchange. After each bath procedure, you should open it for a while, otherwise the air in the room will be heavy and humid, and there is also a risk of carbon monoxide poisoning.

When the furnace is being heated and the room is being heated, the ventilation in the steam room must be closed. After the steam room is fully warmed up, the exhaust dampers can be opened. To exclude the formation of reverse thrust, it is necessary at the stage to make sure that the exhaust openings are larger in area than the supply openings.

In the event that the stove is not installed in the steam room itself, then a different ventilation scheme is used in steam Russian baths. Near at a height of 300 mm. an inlet is made from the floor level, and an exhaust opening is arranged on the opposite wall from it at a distance of 300 mm. from the ceiling. Sometimes an inlet is made at the bottom of the wall behind the stove so that the air coming from the street is heated from the heater and the room cools moderately. On the wall opposite from the heating device, 2 holes are made that will form a single exhaust duct. The first opening is located at a height of 1,000 mm. from the floor level, and the other under the ceiling. With this ventilation scheme, the steam room warms up faster and, accordingly, fuel is saved.

Air exchange device in the washing

In the washing room, as well as in the steam room, there is high humidity, which contributes to the appearance of mold and fungi. To avoid this, it is necessary to create an effective ventilation system in washing baths. In the washing room, a large amount of moisture accumulates under the floor, so to remove it, it will be enough to lay an asbestos pipe, one end of which is under the floor covering, and the other is led out to the roof and equipped with a deflector.

Efficient controlled ventilation in bathhouse sinks will ensure dryness, moderate temperature, fresh air supply, carbon monoxide removal and fuel economy in the premises.

Scheme of ventilation in the dressing rooms

The proximity of the dressing room to the steam room leads to the fact that condensate settles on the wooden surfaces of the sheathing. To preserve the cladding and prevent decay processes, the room must be well insulated and drafts excluded. The simplest ventilation scheme for a dressing room is to remove moist air through a washing or. It is best to organize a forced-type ventilation system for this room.

How to properly ventilate the bath

Having more or less dealt with the ventilation system in the bath, you must also take into account other important points. The exhaust device must not:

cause a violation of the temperature regime in the premises;
allow cold air to rise to the ceiling;
remove fresh air from the room.

The principles by which proper ventilation of the premises is created in the bathhouse depend on the architectural features of the structure of the building. In the event that special slots are provided in the floors for water drainage, then fresh air can flow through them and there is no need to make additional exhaust openings.

Often they make small windows, which, when opened, act as a hood. In addition, if the furnace of the heater is located directly in the steam room, then ventilation is even easier - just open the combustion chamber and adjust the air exchange by changing the position of the damper. These are the simplest, but most effective and low-cost options for installing a ventilation system.

Features of air exchange in frame baths

If in or air circulation is carried out through rows of lower rims, then in frame-type buildings sheathed with a large amount of heat-insulating material, there is no natural ventilation and for this reason it is necessary to provide for the creation of special openings with dampers.

The most efficient system for a bath is supply and exhaust ventilation. To organize high-quality air exchange, it is necessary to create two channels. One of them is located near the floor and serves to bring fresh air into the room (if necessary, you can install a fan), and the second is arranged at a short distance from the ceiling and is necessary to remove hot and humid air masses and carbon monoxide. Ventilation openings in frame baths should be equipped with special control dampers.

When creating a ventilation system, it is necessary to take into account the area and shape of the steam room, as well as the location of the heater.

Chopped bath ventilation

In the Russian bath, where steam was traditionally prepared by hand, forced air circulation schemes are not suitable. In order for natural ventilation in wooden baths to contribute to healing, the following schemes should be followed when creating it:

ensure the possibility of ventilation (creation of windows, door and ventilation openings);
the upper borders of doors and windows should be at the same level;
for steam rooms of a small size, simple ventilation is sufficient;
a heater with a chimney is a natural exhaust of exhaust air and gases;
for normal air exchange, it is possible to equip a ventilation supply opening with a damper and an exhaust opening under the ceiling next to the heater.

The device of good ventilation in a log cabin is a very important point, since it is necessary to exclude the accumulation of excessive moisture, which negatively affects the wooden structure and can cause the development of pathogenic fungi and mold.

Ventilation system in a brick building

You should think about the arrangement of ventilation in brick baths even at the construction stage. Since a brick building does not provide for natural air circulation, the number and location of openings should be taken into account in advance.

The air exchange system in a natural way is identical to that in a Russian bath - the inlet is located next to the stove, and the exhaust is under the ceiling. However, if the bath is designed for a large number of people, then you should think about creating a forced ventilation system.

The fan must be installed at the inlet of the exhaust duct leading to. To speed up air circulation, several exhaust pipes are mounted, but it may be necessary to install supply valves so that the air masses are not discharged due to the difference in the volumes of supply and exhaust air. An overly powerful fan can lead to the same problem, and a device that does not match the area of \u200b\u200bthe room in terms of power will not be able to perform its functions normally and the air exchange in the steam room will be rather weak.

Ventilation Bastu

Recently, new and more efficient solutions have been found to create ventilation systems. Such innovations include the ventilation scheme in the Bastu bath. Among Russians, this system is very popular because of the ease of installation and high efficiency.

The principle of ventilation according to Bast is as follows. The red-hot heater acts as a heat pump and draws air from the supply duct. Cold streams, passing through, heat up very quickly and rise to the ceiling. Naturally, they push an equal volume of near-floor air through the exhaust duct. In the Bastu ventilation system, the supply and exhaust openings are located at the bottom.

For the device of such ventilation, two stainless pipes are required - the lower one is installed diagonally from the heater at a height of 200 mm. from the floor, and the top above the stove. Both outlets must be equipped with damper grilles. However, like all natural-type ventilation systems, Bastu can only work when the stove is running or when there is strong wind outside.

The main advantage of the Bastu ventilation installed in Russian baths is the ease of installation, which you can do yourself, thereby saving your money.

Competent ventilation device in the bath

Normal ventilation can be only if the conditions for the inflow of fresh air and the removal of exhaust air are created in the room. Despite the common concepts - ventilation is not entirely true, since it is always supply and exhaust. The principles of operation of ventilation for any premises are almost the same - fresh air enters through the supply opening and is removed through the exhaust.

When calculating ventilation systems, it is necessary to take into account the volume and purpose of the premises, the presence or likelihood of the formation of carbon monoxide or other chemical compounds harmful to health. Regulatory acts establish the frequency of air exchange within an hour, which can fluctuate 1-10 times or more. Next, the parameters and location of future air ducts are determined, taking into account the climatic zones and weather conditions characteristic of the area. In the event that natural-type ventilation is not able to provide the necessary air exchange rate, then forced-type systems are used.

Where to place a window in the bath?

Windows in the bath are not only a source of light, but also a way to ventilate it. There is an erroneous opinion that the window in the steam room adversely affects the safety of steam in the room and the temperature. However, experienced attendants are advised to make even two windows in the steam room. One window is located above the shelves, and if the steam turned out to be too hot or someone felt unwell, then just open the window and everything will be in order. The second window is placed under the shelves, which allows you to quickly dry the sun loungers. It is made small and opaque.

Important! According to safety regulations, sauna windows should open inward.

It is also worth installing a window in the washing room. It will not only help to ventilate the room, but also to urgently evacuate in case of fire. The dimensions of the window should be such that a medium-sized adult can climb through it. Some bath owners are interested in the question: is it possible to install? If in the washing room, then yes. However, in a steam room, where the temperature reaches one hundred and above, the material from which the windows are made will begin to release toxic substances and warp. For windows in the steam room, it is best to use wood that is not resinous. You can easily install a window in a bath with your own hands, since the technology is no different from installing it in a residential building.

A grate made of wood or heat-resistant plastic and a metal mesh will prevent insects and pets from entering the premises. A corrugated hose or a galvanized pipe is usually used as an air duct. Experts do not recommend installing plastic pipes in a steam room, since they are not designed for operation at high temperatures.
It is advisable to install the fan only on one, for example, on the supply air. Fans used for baths must be made of heat-resistant materials and have good sealing.
A video on how to make a fan with your own hands will more clearly show the process (a bladeless version is presented):
ventilation valves
The ventilation valve for the bath is mounted in the supply and exhaust ducts. There are two types of this device - KIV (air infiltration valve) and KPV (forced ventilation valve). Outwardly, they practically do not differ from each other, and the principle of their work is the same. The outer part of the damper is equipped with inclined shutters to prevent water from entering from the outside, and the inner part is equipped with a head and membranes for sound and heat insulation.

When installing valves, you should follow a few recommendations:
for bath ventilation it is necessary to install dampers made of heat-resistant materials;
installation must be carried out on the bearing walls of the bath;
it is not advisable to mount the valves on the walls facing the or trash can.

Article

The scheme of the steam room is such that it maintains a constant high temperature, and the air must be moist, saturated with water droplets. But in a closed room with such climatic conditions, mold will certainly breed, and combustion processes will be disrupted due to the lack of oxygen, not to mention the fact that people inside will have nothing to breathe. Therefore, it is necessary to design ventilation in the bath. We will talk about it in this article.

Do you need a ventilation system

When building a steam room, novice builders try to fit all the rails and lamellas as tightly as possible, thereby ensuring the absence of temperature losses. This is actually true, but if you do not leave natural openings or artificially created bends, then significant smoke is possible if the stove is powered by wood or coal. Any fuel leaves traces of burning. Carbon monoxide in high concentrations will lead to loss of consciousness and the possibility of death, especially if the people in the room are steamed, with unstable pressure, dilated blood vessels.

Required for the following tasks:

creating the necessary microclimate;
airing and drying wood so that mold or fungus does not occur;
the removal of carbon dioxide, there are people in the steam room, so a constant supply of fresh air is needed;
facilitating the combustion process, for which oxygen is important;
elimination of unpleasant odors;
preservation of lamellas and shelves in their original form.

The principle of operation of the ventilation system in the bath

The entire ventilation network can be divided into natural, which is located in the walls, roof and foundation and is laid at the beginning of construction, and forced, which is activated only when using the steam room.

Both types work as follows: the exhaust oxygen is displaced and the space is filled with fresh air. The flow has two ends - inflow and outflow, respectively, you need at least two holes located according to the rule: supply hoods are lower than outflow ones.

Another nuance of the principle of operation - all the gas is taken from where it goes. That is, if the message occurs with the street, then everything should go there. Similarly - if in the next room, which is also possible. If the inlet and outlet are in different temperature conditions, then the flow will not form. However, it is recommended to do the inflow / outflow of air from the street, since even in the dressing room the air will be humid and insufficiently enriched with oxygen.

Proper ventilation in the bath in the steam room

When designing a building, you immediately need to calculate where the mines will go, what diameter they will be. And the holes themselves and the dampers on them are placed directly after facing with lamellas. There are 4 types:

Finnish - 130mm inflow, 100mm exhaust.
Swedish - 100mm inflow, 80mm exhaust.
Russian - 100mm inflow, 100mm exhaust.

The most common solution, alas, is the lack of a ventilation system.

The size of the holes directly depends on what you want to end up with: a Russian steam room or a sauna.

Consider an example calculation. If the steam room is 3 m by 1.5 m with a height of 2.5 m, that is, approximately 10-11 m3, you need a 20 kW stove. In this case, it is better to use a natural type of air exchange - with an air inlet 10 cm from the floor at a distance of 30 cm from the stove, and a diagonal outlet - under the shelves at a height of 80 cm.

At the same time, it should be taken into account: from under the lining, the valve works only in the only closed position or in the open position. It should not be regulated, as it is made airtight, otherwise the steam will leave. Both outlets do not have to have the same radius, but if more efficient and faster circulation is needed, the first one can be made a little larger or two valves can be installed in different places. It is strictly forbidden to make it smaller than the supply device. This is against the safety rules.

It is imperative to make valves on the ventilation openings, which will hermetically adjoin the opening in the closed state - at the time of kindling and heating the steam room. In winter, these doors will be half closed, because the greater the temperature difference, the more air circulates. The hoods should be at the top, and the inflow should be at the bottom. This will allow oxygen to ventilate naturally. The most popular option today: 100 mm - supply, 80 mm - exhaust.

Types of ventilation

Some 5 years ago, no one spoke about the ventilation system in the bath, moreover, many argued that it was not needed in the bath. Enough presence of a window leaf. Times have changed, and now everyone is for ventilation in the bath. There is forced and natural. The chosen option depends on the area of the steam room, climatic conditions, as well as on the desire of the owner.

Natural

It works on the difference in temperature and atmospheric pressure differences inside and outside. This is a very effective and long used method. There is a nuance for arranging such circulation in the steam room. In the most heated room, due to the natural laws of physics, it is difficult to provide uniform heat. Usually the higher, the hotter, and the floors can remain quite cold. The task of the builder is to think over the system so that the draft does not blow on the legs, and unbearable heat does not accumulate on the ceiling. This can be achieved by dividing the flows into two or three extracts.

Forced

This is an electronic control that depends on the temperature regime. You can turn the fresh air supply on and off as desired. It can be controlled using a digital device - how many degrees should be maintained throughout the entire time the procedure is taken, as well as what humidity the system needs to be adjusted to.

Typically, such complexes are created for commercial purposes, therefore they are much more expensive than elements for natural outflow, and installation can only be carried out by specialists.

One of the main disadvantages of using electronic systems is the possibility of leaving the fan on, which can lead to ignition of the wiring and fire.

Combined

When buying an electrical device, pay attention that they have the maximum protection of all wires and electronics from moisture.

How to make ventilation in the bath through special products

These are gratings made in the walls at the floor level (20 cm from it) and the ceiling. In this case, the maximum distance from each other should be achieved, this can be achieved if they are mounted diagonally, for example, one is installed between the door and the stove, the second on the opposite wall.

Elements for the device of the circulation system, as well as chimneys and tanks for the Russian steam room can be ordered from Ferrum distributors, which are represented throughout Russia. A wide selection and quality of products will help you build a bath complex with your own hands with Ferrum products. can be viewed on the website.

Where to place the cold air inlet

It is located below. You can create it in the wall, but then it is necessary at the design stage to lay a pipe or shaft that will lead inside. In this case, it should be taken into account that fresh air will come from an adjacent room, and, therefore, it should not go out into the street, but into the same room. There is a minus - usually the shelves are installed opposite the entrance structure, and the circulation is felt by everyone present.

Another option involves the installation of air under the sun loungers. In many ways, this is the optimal location - it does not see through, does not spoil the appearance. But just reaching out to it can be difficult to adjust the position of the damper. In such cases, during the bathing procedure, the upper outflow doors are moved, and then both are opened for ventilation.

And another common and winning option is to place the inflow behind the stove. This simultaneously promotes circulation and heating of coals. But there are a few "buts" - sometimes the stove is installed in the wall, then there is simply no way to organize a damper there. And one more thing - because of the intense heat, plastic doors will melt here and wooden doors can start to ignite, so only metal ones will do.

With the output outflow is easier, it can be mounted:

in the ceiling, but then you will have to make an additional box for output through the roof, because if the damp steam is in the attic, the wooden rafters will rot;
in the wall - the best option, it is laid even at the time of the construction of the building.

How to make ventilation in a steam bath: hole sizes

The exact size of the airflow depends on humidity, temperature difference, minimum and maximum values. Experience suggests that the most optimal non-parameters are 10-15 cm, if desired, the outflow diameter can be increased, while flow systems cannot be larger.

In this case, it is necessary to install dampers. It is with their help that you will achieve the required radius when weather conditions change.

It is a common misconception that a person does not have enough oxygen to breathe if the supply is too small. This is not true. For an ordinary person, one cubic meter of air is enough for 1.5 hours.

Floor ventilation device

Why it's important: Wood flooring is affected by a number of factors, with moisture coming in from below, from the ground and foundation, and from above, from steam. Plus, condensation builds up. Such conditions are favorable for the onset of decay and for the spread of fungi and mold.

The most effective is the installation of vents under the floorboards. At the same time, there is no draft and the system can be used in the process of taking bath procedures. Another plus - ventilation occurs as if from the inside. That is, when airing, the upper part of the floor covering dries, and when the hood is running, the lower part dries.

To make this as productive as possible, when draining the steam room, take it to the side so that moisture does not spread under the floorboards.

Ventilation of the foundation of the bath

If you already take care of this when laying the foundation, then you will not have rot and mold in the construction. Air vents with a diameter of 110 mm or more should be installed on all four sides. This will ensure acceptable circulation even if the bath complex is located in the middle of other buildings. It is best to lay these pipes opposite each other.

Ventilation of various auxiliary rooms

The rest of the rooms should also have their own circulation.

Attic

A gable window is not enough, as steam often enters this space and can negatively affect the rafters. It is optimal to arrange the inflow under the roof canopy, and the outflow - on the ridge. So the flows will pass from bottom to top on both sides.

Washing

For the organization of air exchange, forced ventilation is most often used, which directs the flows towards the vestibule.

Ground floor

Owners of private houses can use the basement for a bath. It's possible, but it comes at a cost. Now the integrity of the whole house depends on the safety and efficiency of the circulation system. Already at the design stage of the building, it is necessary to provide for the distance between the walls and the insulation, otherwise condensate from the temperature difference will accumulate on the surface.

It is required to create forced ventilation, since natural ventilation cannot be provided due to the impossibility of installation near the floor (after all, it is underground). We recommend entrusting this issue to professionals.

shower room

Taking into account the fact that in the rest of the rooms there is already an inflow and outflow of oxygen, it is enough just to design air from the fans in the ceiling or at the top of the wall so that the unpleasant smells of dampness come out. You should also do if the bath complex has a toilet.

dressing room

Here, you should also take special care of the circulation of air flows, since due to the close proximity to the steam room, a strong temperature difference and condensation on the walls form in the room. Similarly, the intake-outflow option is suitable. You can also arrange windows that allow you to quickly ventilate.

How to arrange ventilation in the bath and steam room - calculation of the scheme

We have already said about the standard value: 1 cubic meter of space requires 24 cubic centimeters of bends. When choosing pipes, they often stop at pipeline pipes - they are inexpensive and effective, but we recommend assembling such a system from Ferrum stainless chimneys, they have a long service life and do not deteriorate from constant interaction with moisture. The standard diameter is 10 centimeters. So, the cross-sectional area is 78.5 cm2. One such box is enough for 3.27 m3 of room volume.

We calculate the number of cubic meters. Suppose that the steam room has dimensions of 2 by 2 m2, the ceilings are also 2 m high. We multiply everything, we get 8 m3. We divide this by 3.27=2.45. Round up to three. As a result, you need to organize 3 boxes with a diameter of 10 cm for the entire steam room.

Ventilation device

There are several solutions:

The location of the window next to the stove or under it. At least 25-35 cm should remain above the floor. In this case, the flow moves down, then rises along the opposite wall.
Both holes are on the same surface, which is not recommended, but occurs. Then, be sure to install a fan on the hood. This is true when the steam room has only one wall facing the street, and the rest are adjacent to residential areas.
The cracks in the flooring, if you have a multi-layered leaky floor, can draw in air, pass it through the space under the covering, and then return it up again. This ensures good ventilation of the floorboards.
If the inflow is located opposite the stove, then it will work only if the heating is on.

All these types are presented schematically in the picture:

In the article, we talked about how to properly ventilate the bath, showed diagrams and explained the structure of the steam room. Design your bath complex together with high-quality products from Ferrum. On the site you will find chimneys and accessories for arranging a bath. Bathe in pleasure with Ferrum.

Useful videos

Russian bath is very beneficial for health. The fundamental point in its construction is well-equipped ventilation in the bath in the steam room. In this room, as a rule, very high temperature and humidity. Properly organized air circulation is a necessary condition.

Often, many homeowners doubt whether ventilation is needed in the bath in the steam room. The proposed material will allow you to correctly answer this question and solve all the problems with the arrangement of ventilation without much difficulty and without significant material costs.

Ventilation in the steam room is necessary for air circulation

Why do you need ventilation in the steam room

Proper ventilation of the sauna steam room helps to solve the following problems:

maintaining a comfortable indoor temperature;
health safety;
the preservation of the wood used for the interior decoration of the steam room.

Ventilation products in the steam room help to regulate the temperature, and keep the wood from dampness and fungus longer

If the ventilation of the steam room in the Russian bath is not properly equipped, the appearance of such negative factors as:

rapid cooling of heated air;
accumulation of gases during the adoption of procedures;
premature decay of finishing materials;
the appearance of harmful microbes, bacteria, mold, fungi;
bad smell.

The proposed material will describe in detail what should be properly organized ventilation in the steam room of the bath, video and photo materials will clearly illustrate all the key points.

Basic principles of steam room ventilation

A specific scheme for arranging ventilation is usually selected taking into account the architectural features of the building itself, the size, number of rooms, etc. In this case, it is necessary to strictly observe the basic principles for arranging ventilation systems for steam rooms in Russian baths. If they are violated, various negative phenomena can occur that create a serious threat to the health and life of vacationers.

The fresh air inlet is located just above the floor level. In order for the incoming air to warm up immediately, the inlet is located in the immediate vicinity of the furnace.

The outlet for used air is located under the ceiling. The main thing is that the inlet and outlet for air be equipped on opposite walls.

Important! Under no circumstances should these holes be placed at the same level! The air in the interior space will not fully circulate. There will be a temperature difference that creates a serious health hazard.

The dimensions of the inlet and outlet holes are identical. They are selected depending on the dimensions of the internal space of the steam room. For 1 cu. m of air requires 24 cm of pipe diameter. If necessary, arrangement of additional air outlets is allowed.

The ventilation of the steam room is arranged in such a way that the exhaust air is completely replaced every 3-4 hours. This is required by sanitary and fire safety standards.

The vent in the bath is equipped with valves to regulate the air flow

The ventilation device in the steam room of the bath requires the mandatory placement of a valve system. You can use special blinds for this. This will allow you to control the amount of air entering and exiting. If necessary, the bath can be heated or cooled very quickly and without much difficulty.

You need to think about how to make ventilation in the steam room of the bath already when drawing up a project. This will allow you to correctly place all ventilation pipes, openings, etc. during construction. This will allow you to properly equip the mines, lay pipes and perform all other work. It will be much more difficult to equip the air circulation system after the completion of construction work.

Before building a bath, it is necessary to consider the location of the ventilation ducts in the bath

Varieties of ventilation systems for the steam room

Ventilation in the bath in the steam room (see photo) is used in 3 types - natural, forced (i.e. mechanical) and combined. The choice of a particular system is made taking into account factors such as:

the size of the steam room and the dimensions of the building as a whole;
it is possible to correctly place the exhaust pipes;
the material from which the bath was built;
use of the bath all year round or only in the summer season.

Warm air is lighter than cold air. Therefore, with properly equipped ventilation in the bath in the steam room, heated flows rise to the ceiling and are gradually drawn out through the vent. The air coming from the outside is immediately heated from the stove and passes into the room without creating a temperature difference. Here is the basic principle by which ventilation works in the bath in the steam room.

natural ventilation

The natural ventilation system provides air exchange due to different levels of pressure and temperature in the internal space (in the steam room) and outside, i.e. on the street. When the exhaust air exits through the outlet, the internal atmosphere in the room is discharged, creating conditions for drawing in cold air through the bottom inlet. In this case, special attention should be paid to the insulation of the bath. Otherwise, high-quality heating will not work.

Natural ventilation in a steam room in a frame bath is most often used for small buildings built from breathable material, i.e., from wood. Additional elements of the ventilation system in this case are small gaps in the log walls. The main advantage of natural ventilation is its low cost.

Forced and combined ventilation

A mechanical or forced ventilation system in a bath in a steam room is necessary if:

the total area of the bath is large;
the building was built of brick, cinder blocks, stone;
the steam room is very large;
exhaust pipes cannot be placed correctly;
heavy duty oven.

Do-it-yourself forced ventilation of the steam room of the bath is mounted without any problems. It uses:

fans;
supply valves;
deflectors.

Forced ventilation in the bath is suitable for large rooms

Nuance! The ventilation system in the bath in the steam room, heated with a geyser, requires the arrangement of a separate ventilation duct.

The combined ventilation system is equipped using elements of both systems described above. Fresh air enters naturally, i.e. through the lower inlet. Extraction of exhaust air masses is provided by mechanical devices.

How to choose a steam room fan

A classic duct-type fan for a steam room is not suitable. High temperature and humidity are detrimental to such devices. In the steam room, fans of a special design are used. The material for their manufacture is glass-filled polyamide. Such models are resistant to moisture and can withstand temperatures up to 130 ° C.

Glass fiber reinforced polyamide is an ideal material for steam room fans

The fan model is selected in accordance with the technical specifications.

It should be remembered! Ordinary room fans can only be used for the final drying and airing of the steam room after the adoption of procedures and subsequent cleaning.

If you have money, you can install a self-regulating system for ventilation in the bath in the steam room. This device will automatically provide air inlet and outlet, temperature, humidity level. It is advisable to purchase such systems only from trusted manufacturers.

Basic schemes

What can be the ventilation in the steam room of the bath, the diagram, video and other materials attached below will show clearly. You just need to choose 1 of the 4 attached options and correctly perform all the necessary work.

According to scheme A, the fresh air inlet is arranged below the stove. The outlet channel is mounted on a directly opposite wall under the ceiling.

The exhaust pipe is installed vertically. Its length is calculated so that the upper edge of the pipe rises slightly above the roof ridge. This will ensure the normal functioning of the ventilation system during strong winds.

Scheme A of the location of ventilation in the bath

Properly selected sizes of pipes for exhaust air will ensure the natural circulation of air masses. Additional adjustment is provided by the installation of dampers.

The use of scheme B is assumed only if only 1 of the walls of the steam room can be used for arranging ventilation. Air openings are located opposite the heater. The inlet hole is raised 30 cm from the finished floor. The outlet window is lowered 20 cm from the ceiling.

Scheme B Arrangement of ventilation ducts in front of the heater

The air passing through the bottom inlet is heated by the furnace and rises in the direction of the air outlet. Mechanical pulling devices are necessary for the normal functioning of the system.

According to scheme C, it is possible to provide ventilation not only for the steam room, but also for the underground space. The inlet hole is arranged in the wall behind the heater. It must be raised above the finished floor by 20 cm.

Scheme C with air supply under the floor of the bath

The heated supply air passes into the basement through the cracks of the leaking floor. Then it returns to the steam room and moves towards the exhaust opening. From here, the exhausted air masses go outside.

For a constantly used bath, ventilation according to scheme D can be used. In this case, the inlet is arranged at the bottom, but opposite the stove, and not behind it, as in other options. Height above the floor - 20 cm. Extraction of exhaust air is provided by means of a blower and a chimney.

In order for the ventilation in the bath in the steam room to work effectively, it is necessary to choose the right location for the stove. It is most convenient to equip it inside the steam room. If the stove is located in an adjacent room, the efficiency of the ventilation system and the heater itself will be noticeably lower.

Preparatory work

To arrange ventilation in the steam room, it is necessary to prepare the following materials:

brick and/or stone;
cement and sand;
ventilation ducts;
finished valves or material for their manufacture;
a metal sheet;
lining for lining the box;
fixing material - nails, screws, self-tapping screws.

To work, you will need the following tools:

hacksaw;
Bulgarian;
a hammer;
screwdriver;
tape measure, level, plumb;
construction mixer;
drill or perforator;
a set of spatulas;
container for mixing the solution;
technical knife;

Work is best done in special clothing. Wear gloves and a respirator if necessary.

Supply ventilation installation

The inlet channel for supplying fresh air is located in the immediate vicinity of the furnace of the sauna stove. It is desirable that the inlet is located above a sheet of metal sheathing that protects the wood from the accidental ingress of small coals.

First, you need to make a box from a suitable material. Its dimensions should exceed the dimensions of the chimney by about 20%. The outer opening of the box is located on the outer wall. It is undesirable to place it in the basement.

If the firebox is located in the actual steam room, a convection box is additionally equipped. At the wall in which the air inlet is located, you need to lay out a podium of bricks placed “on edge”. They are laid out in 3 rows - under the wall, in the middle and on the edge.

The masonry for the oven is arranged to a height of 25 cm. It must be brought to a brick screen and must be blocked. In order for the newly incoming air to pass directly into the furnace, it is better not to lay the last 2 bricks. The butt is lined with bricks.

The convection box is mounted to the end. At the end, a blower is equipped. Under it is a protective substrate for the safety of the floor covering.

When the podium is completely ready, you can start installing the furnace. To evenly distribute the load, it is desirable to use a corner made of metal.

After the final installation, stone or brickwork is arranged around the furnace. To form a gap, it is moved 5-6 cm from the furnace. Next, a special screen is installed. It needs to form holes for the passage of hot air.

Installation of outflow ventilation

The outflow box is installed diametrically opposite from the inlet. It is raised above the finished floor by 30 cm. The inner area of the box is approximately 1.25 m².

Through the wall, the outflow duct is led to the ceiling and an external outlet is equipped for it. You can remove the exhaust air to an adjacent room. In this way, it will be possible to warm it up without extra costs.

Outflow ventilation can be placed on top of the ceiling

To avoid accidental burns, the chimney box must be lined with a brick or stone casing. At the same time, a special hole with a door must be left below, which will be a blower. An additional hole, equipped on top, will allow the chimney to be used as a heat pump, this will create both heating of the room and proper air circulation.

How to ventilate a Russian bath

The correct ventilation device in the steam room of the Russian bath does not involve the use of any mechanical devices. Otherwise, the heated air will be expelled very quickly. Efficiency and pleasure from bathing procedures will decrease significantly.

In the Russian bath, natural ventilation is used, where the outflow of air is carried out through the window.

Therefore, the Russian bath must be carefully cleaned, ventilated and dried after each use. For ventilation, a special window is installed in the wall opposite the door. You can use a mechanical extractor. The door must be kept open for ventilation.

It is necessary to remove leaves from brooms and random objects from the beds. Then you need to wash all surfaces and dry them with towels and / or a special absorbent cloth. This will protect against the formation of mold and the reproduction of harmful microorganisms. After cleaning, airing and drying, the steam room is ready for further use.

The steam room in the Russian bath is combined with a washing room, so it needs to be dried after each use

How to warm up a Russian bath

First you need to fire up the oven. The outlet openings must be kept closed. Only input opens.
