Air heater for home. How to make air heating of a private house with your own hands. Air heating using fan heaters, gas or electric heat guns, convectors

Systems organized according to the principle of heating with heated air are successfully used for heating workshops, warehouses, administrative buildings, private houses and other Objects.

This type heating can be carried out different ways and using different equipment. What these systems have in common is the absence of any coolant other than air, and auxiliary elements in particular radiators.

Types of air heating

There are two fundamentally different schemes for this type of heating.

Air heating combined with ventilation

The transfer of heated air is carried out using elements supply and exhaust ventilation. In this case, the operating parameter is not only the temperature in the room, but also the set air exchange rate.

Heat is generated by boilers or gas heat generators. A system of air ducts is connected to them, through which warm air is distributed over all areas of the heated premises. The system can be supplemented with filtration, humidifier, recuperator.

Air heating using fan heaters, gas or electric heat guns, convectors

It implements the so-called direct heating. Inside the room, one or more devices are installed that generate and distribute warm air. The heated air spreads in a certain direction, gradually mixing with colder air. It is possible to combine such heating with recuperation systems.

Regardless of the chosen scheme, preliminary is recommended for implementation in any case.

Appropriateness of application

It is advisable to use an air heating system in the following cases:

  1. If necessary, organize heating as soon as possible
  2. For heating large rooms with complex configuration
  3. If necessary, the organization of zones with different temperatures
  4. The air heating system can be used as temporary heating during construction, renovation or finishing works. This system can, if necessary, be modified to the level of a permanently functioning one. And in the future to use it as the main or backup
  5. With a limited budget, the heat source for heating with air is commensurate in cost with hot water boilers of equal power, and air ducts are much cheaper than pipes, fittings, radiators used in heating systems with a liquid heat carrier

Features of heating with heated air Industrial and manufacturing facilities

Organization of air heating combined with ventilation in private residential buildings differs from the implementation of air heating systems Industrial real estate objects - warehouses, workshops, hangars, repair shops, etc. These differences are associated with the scale of industrial facilities, a large volume of heated spaces, increased requirements for functionality and reliability.

We list these nuances that our specialists usually face at industrial facilities:

Currently, air heating of a private house, organized according to the so-called Canadian method, has become quite widespread in frame houses. The thickness of the walls and roofs in them is relatively small, they are not able to retain heat in the house, even taking into account the gasket thermal insulation materials. Traditional with the installation of water communications in big houses is often costly and complex.

In this case, an air heating system combined with ventilation may be the most optimal solution with high efficiency. This method of heating domestic premises has long been successfully used in the United States and Canada.

The principle by which the air heating of a private house is built is similar to that used in the organization of such systems at industrial facilities. The heat source heats the air coming through the ducts to all heated rooms.

But there are some peculiarities. Air ducts that are used in houses, as a rule, have a smaller section compared to air ducts installed at industrial facilities, and in the lion's share of cases they are laid hidden. They are covered with suspended ceilings, hidden in the space under the floor, behind the walls or decorated to match the design of the premises.

Samo thermal equipment, as a rule, this is a household gas or diesel air heater, heat exchanger, filter, humidifier, automation devices, also visually closed.

Another difference from industrial systems is that the source of warm air is located in one of the rooms, while at production facilities it is usually taken out to separate room- boiler room or heat generator.

The main pros and cons of using air heating technology

The widespread use of air heating technology at various facilities is due to its many advantages. The main ones are:

  • High efficiency. In some systems, its value can approach 90%. For comparison, heating system with coolant has an efficiency of less than 60%
  • Ability to warm up large area, including in the central areas of the premises
  • Low installation and operating costs
  • Compatibility with the ventilation network. Possibility, subject to connection to a ducted air conditioner, to use the system for cooling in the summer
  • The absence of a liquid heat carrier in the air heating system, which eliminates the occurrence of emergency situations (frost, leaks)
  • Low level inertia. Rooms heat up very quickly
  • The ability to stop the system even in very coldy without the risk of failure

But there are obvious disadvantages of these systems, from which we can distinguish:

  • Warm air tends to rise up, so for the most efficient and uniform heating, it is advisable to lay a network of air ducts in the lower part of the room or hide them under the floors. Unfortunately, it is often impossible or very difficult to do this, especially at industrial facilities.
  • The use of air heating technology can cause all the dust that is present on the floor surface in the house to rise. If you do not clean the premises often, the air will be dusty.
  • The complexity of the calculations of such a system. In order for air heating in a small private house or at a large-scale industrial facility to function effectively, this system must be professionally calculated. These calculations are quite complex and much more complicated than the calculations required when organizing a water heating system. They need to take into account many parameters. It is necessary to calculate: heat losses in the serviced premises, type and required power of the heat generator, optimal air flow rate, air exchange rate, necessary and sufficient cross-section of air ducts and other specific engineering parameters

After analyzing the above, it becomes obvious that the air heating system is located at the junction of two engineering sections. These sections are heating and ventilation.

Accordingly, the Contractor to whom you entrust the execution of work at your Facility must have such specialists or generalists who have experience in the calculation, selection and installation of such systems.

It must be taken into account that if the air heating system is executed with errors, then it will not only fail to cope with its intended purpose - to provide the necessary comfortable temperature in winter period. But it can also be noisy and quite expensive. With hidden laying of air ducts, reworking such a heating system that does not work correctly is a very expensive and problematic event.

Choosing the right heating system - milestone construction and arrangement of a private house. Solid and liquid fuel units are gradually fading into the background. Do-it-yourself air is gaining wide popularity; almost any owner of suburban housing will be able to carry it out. This article will tell you how to do this.

Air heating - what is it?

This method of heating is a kind of thermoregulation system, in which cooled or heated air enters the room. Almost everyone can do air with their own hands, the main thing is to understand the principle of operation of the system and its composition. It includes:

  1. Branched air ducts. They provide air flow access to heated rooms.
  2. Water heater or heat generator. It heats up the air.
  3. Fan distribution heads. They direct the air masses inside the room in the right direction.

Principle of operation

The heat generator usually includes a combustion chamber, a burner and a heater. From below, from under the fan, cold air enters the heat exchanger. The fuel that is burned in the combustion chamber releases energy. Due to it, the heat exchanger heats up, which means that the temperature of the air that was in it rises. Further, the heated flows enter the air outlets and are sent to the room. Heat generators are different types, some work on main or liquefied bottled gas, others - on diesel fuel. The burner, due to its versatility, can burn any substance. In any, even a standard heater, the burner can be replaced. Together with it, the entire supply system is mounted. All exhaust gases exit through the chimney.

The air heating system of a private house involves the use of air vents of one of two types: round or square. The former have minimal aerodynamic resistance, their diameter is 10-20 cm. Square or rectangular air outlets are made in the form of boxes. Most often, parts with an area of ​​\u200b\u200b10 * 15 or 32 * 40 cm are used. Such air vents are easier to install and take up less space.

Advantages and disadvantages of air heating

The air heating system of a private house has both pros and cons. The advantages include the following features:

High level of efficiency (more than 90%);

Absence - radiators and pipes;

Comfortable microclimate in a heated room;

Low inertia of the system, which allows you to quickly heat the house or lower the temperature if necessary;

Fans can be used in conjunction with solid fuel stoves, this allows you to heat all the rooms in the house;

Air purification from allergens and other harmful substances thanks to filters;

Possibility to connect the system with a humidifier;

AT summer season With the help of additional draft, you can cool the room.

air heating a private house, the disadvantages of which we will consider below, is far from a perfect system. She has serious shortcomings:

This type of heating should be laid at the beginning of the construction of the house;

The complexity of installation;

Calculation of the diameters of the air outlets before laying;

Air heating requires constant maintenance;

Upgrading the system during operation is very difficult;

Air heating requires additional filtration and air humidification;

In the event of a power outage, a backup power source must be available.

Types of air heating

To mount the air heating of a private house with your own hands, you should understand the installation methods. These systems are built according to 2 schemes:

Forced;

Gravity.

The first scheme assumes the presence of a fan in the system. It creates the necessary pressure, and the air heated by the heat generator moves to the air outlets. Its location is usually the same regardless of the type of system - it is located under the heater. The air that enters the fan is already pre-cleaned from dust, dirt and microbes. It returns back through ventilation grilles or return air vents.

Do-it-yourself air heating of a private house, made according to a natural or gravity scheme, functions by changing the main advantage of such a system is that it is practically independent of the supply of electricity. But the circulation of heated air masses can be easily disturbed by an ordinary draft. The working part of the room is cooled, and the pre-ceiling, on the contrary, overheats.

Features of direct-flow heating system

Do-it-yourself air heating of a private house is often done using once-through system heating. The principle of operation is the following. The air is driven by the fan through the heater and passes through the channels into the room. It gives off heat, assimilates allergens and microbes, and leaves through the return shaft. This system is recognized as the most hygienic and safe, but at the same time it has its drawbacks. The main disadvantage of direct-flow heating is high energy.

Recirculating heating system. Nuances

Such a system is characterized as highly economical heating. The air is heated in the heater and sent through the ventilation channels to the premises. Then it cools, compensates for heat loss and returns back. Then the air is heated again, and the process repeats. Certainly, this system is the least hygienic harmful substances enter the premises again. Recirculation is provided where ventilation as such is not needed.

Design and calculation of an air heating system

To install air heating with your own hands, calculation, scheme, the device of which must be taken into account during the installation process, some preparation is required. Once you decide to install such a system, you need to draw up a preliminary project. It is necessary to calculate the following indicators:

Heated air supply rate;

Sufficient power of the heat generator in order to heat the room to the desired temperature;

Diameter of air outlets;

Aerodynamic characteristics;

The amount of heat loss on the ceiling, walls and floor.

Air heating of a private house, the scheme of which will help to take into account all the constituent elements, must be agreed with specialists. They will help you complete necessary calculations. By contacting a special service, you can avoid drafts in the room, noise and vibration in the house, as well as overheating of the heat generator.

It is better to think over the place of installation of equipment in advance, some general recommendations about it does not exist.

Selecting a heat generator

Unfortunately, not everyone prefers to install air heating in a private house. The cost of the system device largely depends on the choice of heat generator. They are of two types:

Mobile;

Stationary.

Gas mobile heat generators are very bulky installations. Most often they are used in industrial facilities. Let's take a closer look at stationary equipment. These heat generators have a closed combustion chamber. They are installed in pre-prepared places with a smoke exhaust system. Stationary heat generators are available as floor or suspended equipment. The latter is otherwise called heaters. They are designed to heat one room. Most often, the heater is used in country cottages and dachas, as it is able to warm up the room in a matter of hours.

The suspended heat generator does not take up much space and is very quiet. The body of the unit is made of materials with low thermal conductivity, so it is safe to use.

The floor generator is a more voluminous apparatus. It is able to heat the house completely thanks to the connected air outlets.

Mounting equipment

Air heating private country house, made by hand, provides for the following equipment:

air outlets;

Heat generator;

fan;

decorative grilles;

Sleeves for an air intake outside of the room.

Installation instructions

Do-it-yourself air heating is installed (the scheme, the device of the system were discussed above) in several stages:

  1. Boiler and heat exchanger installation.
  2. Wiring, installation of air outlets.
  3. Insulation of return and supply channels.
  4. Creating a hole in the wall of the house for air intake and installing a sleeve.

Air heating of a private house (reviews confirm this) begins with the installation of a boiler. It is usually installed in basement. It is strictly forbidden to connect the boiler to the gas main on your own, you must definitely call a specialist. The chimney can be made from a sheet of tin. The upper part of the heat exchanger is connected to the supply air outlet, and a fan is installed under the combustion chamber. With outside a return pipe is connected to it. The first stage has been completed.

The wiring process begins with the connection of flexible air outlets to the supply channel. They are usually made with round section. Next, a return air outlet is mounted, usually it has a larger diameter, however, such a channel has fewer outlets than the supply one.

To prevent condensation in the sleeve, it must be insulated. Next, a throttle valve is installed in the pipe, with the help of which the process of regulating the amount of incoming fresh air. After the system is installed, you can hide all pipes and wires drywall boxes for more aesthetics.

So be or not be this system - and This is how the question can be raised when the air heating of a private house is discussed. And if applied to our climatic conditions has already become a classic of the genre, there are many rumors and legends about it. It's time to clarify the situation, and help us in this FORUMHOUSE users! But first, let's look at the experience of our compatriots living in the United States - is it applicable in Moscow and our other cities, at least partially.

OnlyOn :

– I constantly communicate with relatives living in the American town of Janesville, not far from Chicago. The climate there is similar to ours. And in all the houses assembled by frame technology installed air heating and air conditioning systems.

The air heating system of the house works according to the following principle: a heater, electric or powered by solid fuel or natural gas, located in the basement of the house. Air is taken from the street and, heated in winter and cooled in summer, is distributed through air ducts throughout the house.


Read about how to choose your own for your home and country house.

And in each room under the windows, in the walls, in the floor there are exits closed with adjustable bars. Thermostats with manual or automatic adjustment air temperature.

Let's see if we can use such a system in relation to our climatic conditions.

Forum user with nickname Traks.

- At our forum, it has already been discussed more than once, air heating of a house, and not only a frame one. But here implemented projects, very little. It seems to me that this system, we have not yet justified the cost, as the equipment itself, as well as its installation and operation.

But the traditional, for us Russians, types and, hot water in radiators, stoves, fireplaces, heat generators, operated for more than one year - live and flourish. So is it worth experimenting, because usually everything new needs in running and at first perceived with a certain degree of skepticism.

But our forum member with a nickname Anchous, going to equip his frame house with an area of ​​150 m2 with an air heating system.

– I want to separate heating and ventilation into two zones - public and sleeping, so as not to heat up what is not currently used in vain. I also plan to provide exhaust ventilation office, so that you could smoke there with a clear conscience.

Let us consider in more detail the principle of operation of such a system.

Anchous:

- It is planned to have a general circulating heating and a separate supply of fresh air to each zone, an extract, respectively, each also has its own separate supply and extract in the office.


The operating modes will be as follows:

  • Circulation with an inflow is the main mode when someone is at home;
  • Circulation without supply - maintaining the minimum required temperature when no one is at home;
  • Circulation without supply (quick warm-up) - after SMS "Going home";
  • Displacement ventilation - rapid ventilation, recirculation dampers are closed.

An article about the ventilation system is available at this .

But such a system also has its pitfalls.


viktor50:

– Ve ventilated home heating is complex system. H you need to calculate how many valves and other control devices you will have, because. all this can fail, and adjustment can stretch for an indefinite time, and cost a lot of money.

An air heating system is a complex engineering structure. And it is necessary to develop it at the stage of designing a house!

Also, with an air heating system, it must be taken into account that:

  • A filtration system is required;

Without it, the air heating system at home is a fiction, since the air in front of the stove must be cleaned. Otherwise, the furnace will burn waste products with the intake of combustion products directly into the room.

  • The mechanical filter must be cleaned every month, the electrostatic filter once a quarter, the coal filter once every six months;

If you clean less often, then the flow of dust into the heat exchanger increases, where it begins to burn out.

  • It is necessary to install an antibacterial filter, because. warm and humid air flows through the ducts.

But despite a number of complex technical issues, which you need to pay attention to, the use of a correctly calculated and installed air heating system, according to our user with the nickname TGSV has the following benefits:

– Not present in the heating system , which causes a significantly lower thermal inertia and much faster heating of the surrounding space than in the case of using water radiators.

Low inertia provides an opportunity for flexible control of air heating operation. The temperature in the heated room is controlled by built-in automation and a remote thermostat.

When the desired temperature is reached, the air heater turns off, and when it drops by 0.5-2g. (depending on settings) is activated again. The operation of the unit can be programmed by the hour and by the day. At correct calculation systems to provide a temperature of 20gr. the unit will turn on for 15-20 minutes per hour. And during the period when there is no one in the house and there is no need to keep 20g. then 5-10 minutes per hour.

TGSV:

– Air installation can be useful in the summer. It is the best suited for combination with cleaning, air conditioning and humidification systems.

Thus, in addition to centralized heating and ventilation, the user also acquires central air conditioner. Those. collectively, this is the installation of a full-fledged climate control based on one air duct system, with the possibility of zonal air distribution throughout the house.

As additions, multi-stage air filters from mechanical to electrostatic, ultraviolet lamps for bacteriological cleaning, automatic are integrated into this scheme. The operation of the entire complex is controlled from a single control panel, including using remote access technologies via the Internet.

The experience of operating an air heating system by our forum member with a nickname is interesting Hope_Kyiv:

- I have a frame house with an area of ​​300 sq.m., plus a basement monolithic mezzanine floor of 70 sq.m. Heated area 250 sq.m. Gas heating, electric air conditioning. In 2010, 2,500 cubic meters of gas were spent on heating plus electricity costs - a fan for heating a house drives air through pipelines into heating season$20 for 6 months. Air conditioning costs about $1. in a day.

DIY

As mentioned above, an air heating system is the best suited for equipping it. But it must be borne in mind that the heat loss of such a house should be minimized and even at the design stage, space must be left between the walls for laying pipes and ventilation ducts.

TGSV:

- Large main air ducts, usually hidden in built-in wardrobes, under stairs, in corridors, attics, technical undergrounds. Air ducts with a section of 250x80 are bred through the rooms. if it is not possible to pass them under the floor or in the attic, then the suspended ceiling will eat no more than 100mm. Now there are more modern high-pressure systems, they use flexible ventilation ducts with a diameter of 70mm.

An air heating system works best in combination with, but the experience of our forum member is indicative Andrew who decided to independently manufacture such a heating system based on a solid fuel boiler.


Andrei.:

- I have a frame house 8x8. Insulation - foam plastic 15 cm - floor, ceiling and walls. Heating TT stove Professor Butakov installed in the attached garage. Four air ducts run from the stove to the corners of the house under the floor. Air is driven by a fan through the oven. The exit of hot air in the floor in the form of a conventional iron ventilation grille. Air intake is partly from the house, partly from the street through air ducts.

Thus, heating and ventilation of a private house are simultaneously carried out.

Andrei.:

- In winter, at night it was -38 degrees outside. in the afternoon 31 gr., at home always + 25 + 27. Cold air (30-70%) from the street is mixed with warm (70-30%) from the house and through a filter (100 rubles) - a fan - the stove is fed into the house. Excessive pressure is created and if there are gaps somewhere in the house, then cold air from the street does not blow into them, but rather blows out of the house.

The stove itself, according to the forum member, is heated around the clock, without interruption. And the thermal energy from one bookmark of firewood is enough for 8 hours if it is fired with pine and 12 hours if it is fired with larch.

The outlet pipes on the furnace were combined with a tin box into one air duct. Hot air comes out from the top, cold air comes in from the bottom. Two insulated air ducts depart from the furnace to the left and right. And under the floor of the house, the air ducts are divided into rooms by a tee.

Sometimes you can hear the opinion that the air heating system is too noisy.

Hope_Kiev:

- I have warm air coming from the floor near the windows, creating thermal curtain near the window, rises up and climbs the grate, which is located in the hall near the stairs much higher than our head, therefore, we do not feel the forced flow.

Andrei.:

- I don’t feel the movement of air, only if you stand near the grate, you can see that the curtain is barely noticeably swaying. No dryness either. Air duct with a diameter of 100 mm. with hot air, insulated with isover with foil enters the house under the floor. Next comes between the lag. And it comes out from under the floor in the four corners of the house.

Let's calculate the cost homemade system, Was wasted:

  • Boiler - 25t.r;
  • Pipe, sandwich (6 meters) - 12t. R.;
  • Air ducts - 2t. R.;
  • Fan - 3t. R.;
  • Filter - 100 rubles;
  • Filter housing - 500 rubles;
  • Silencers (2 pcs.) - 2t.r.;
  • Furnace sealant - 200r;
  • Self-tapping screws - 100 rub.

Andrei.:

- And before that, I water heating learned in the company. Boiler + pipes + radiators + work - they counted me for 320t.r.

FORUMHOUSE users can learn about the best and how to install an air heating system on their own, participate in a hot discussion on the "" topic. Watch our video about

Building own house, you need to take care of the choice of heating for it. AT modern conditions manufacturers offer many solutions that can improve the efficiency of this process. Some technologies require upgrading gas systems heating, and there are options less popular in our country, but successfully implemented abroad.

Air heating systems are one of these methods of heating houses. The leaders in the introduction of such equipment are the countries of the North American continent. There, private households in most cases are equipped with this type of heating installations.

Relevance of implementation

The air heating system is characterized by thermoregulation modes, in which the air brought to the required temperature (heated or cooled) is supplied through channels branched in the room directly to each room.

This layout option has certain advantages over classic radiator heating systems:

  • the design does not use an intermediate coolant (water or antifreeze), which greatly facilitates maintenance, the need to control the required volume of water or the presence of airing the system;
  • there is the possibility of zoned space heating with individual temperature conditions for each room depending on the current situation;
  • there are no radiators in the scheme of the air heating system, which allows rational use of space and increases the safety of rooms for small children;
  • the overall heat transfer coefficient is relatively high, while the costs of heat generation are minimized;
  • an additional electronic air filtration is built into the system, providing protection against the spread of dust and harmful microorganisms.

Comparison of air with water systems

The main competitors for air heating systems of a private house are systems with a liquid heat carrier. Therefore, it is appropriate to compare them according to the main parameters:

  • Due to the absence of an intermediary heat carrier, it is possible to increase the overall efficiency of the system, which reaches in different models air systems 80-95%. The presence of a programmable thermostat in the circuit can increase additional savings of 5-15%. In this case, standby modes are used, which lower the temperature in the absence of hosts by 5-7 0 С.
  • The minimum inertia allows the equipment to enter the operating mode in a matter of minutes. Since there is a rapid circulation of air, it is also possible to heat the room in 10-20 minutes, depending on its volume.
  • Since the system does not have liquid in branched lines, even with a significant decrease in temperature, there is no freezing of the system.
  • The maximum degree of automation makes it possible to generate exactly as much thermal energy as needed to reach the specified mode, reducing losses and responding flexibly to the current demand.

The effective service life of air heating at home according to the Canadian method is up to 40 years. In this case, it is possible to mount, as an addition, an air humidification unit.

Principle of operation

The main element in the circuit is the air heater. It is equipped with a fan that blows air to transport it to the place of use. The jet passes through the installed filter. The following elements can act as a heat generator:

It is appropriate to use heat generators for air heating on solid fuel in regions where this type of fuel is widespread.

The intake of internal air is carried out through the built-in channels, through which it is sent through the filter to the heat exchanger, where the thermal energy is transferred to the incoming flows. Indoor heated air receives a small portion of fresh air from outside, thus ensuring the flow of pure oxygen into the room.

The external air intake is installed along the perimeter of the building in the area of ​​windows or doors, where the greatest heat loss occurs. The procedure is cyclical, allowing you to achieve the desired temperature on the thermostat. All control of the system is carried out through a thermostat, which can be programmed to various modes, for example, summer/winter, variability by time of day and days of the week.

In the warm season, the entire system is quickly reconfigured to the cooling mode. The air circulation is carried out not through the heating elements, but through the refrigerants.

Varieties of heating air systems

There are several popular systems that use a variety of operating principles. The most popular of them are direct-flow and recirculation heating systems. Let's take a look at their device.

Straight-through

A direct-flow system requires a separate room in ground floor or basement. Air heating is carried out by burning hard coal or wood. It then moves on thanks to natural process into the upper cavities located behind the opening in the floor or in the walls. Next, it goes outside. At the same time, he manages to give thermal energy building elements - floors and walls. This type has a lower efficiency, so it is used much less often, although it is cheaper than the others.

Recirculation

Recirculating air heating systems in most cases are used to heat the air gas-burners together with a large number filters. The heated air passes through all channels and enters the upper area of ​​the building, where, cooling down, it descends and, together with the volumes of new air replacing it, circulates in the system. In the process, you can rely on natural circulation due to thermal expansion. However, it is more efficient to use forced displacement air through the installation of fans.

Combined variant

These are various combinations of air-water or oil-based space heating schemes, which are offered in most cases for several interconnected by a single air line. The principle of operation is that the coolant is supplied from the boiler room to all rooms, and a very powerful radiator is used as a heat-releasing element.

Example of an organization with partial fresh air supply

These principles of operation have been tested in large industrial premises in our country, but they are also promising for implementation in living conditions private housing constructions.

What is needed for the installation of air heating

And although today only in Russia there are several thousand companies for the installation and installation of air heating, it is easy to assemble it yourself.

The first and main thing is to choose a heat generator that will produce heat into the house. The brand of the heat generator and its power depend on the area of ​​\u200b\u200bthe house or apartment where such a system will be installed.

What else is needed to install the system:

  • flexible air duct - a special galvanized pipe through which hot air will circulate;
  • tees for connecting pipes and creating a full-fledged air line;
  • gratings for hot air supply and cooled air intake;
  • aluminum tape to ensure the tightness of the air line connection;
  • blade and mounting hardware.

Varieties of air ducts

  1. The ideal option is when ventilation ducts are designed at the stage of building a house, for which special niches are mounted in the walls or ceilings, the size of which is sufficient for the location of the air duct.
  2. When installing heating in an already built house, you will need to build false walls or dropped ceilings, which can mask massive pipes.

In general, this is a convenient and promising heating system, in which a minimum of funds is spent on heating. There are some nuances in the arrangement and installation, but these are really subtleties that, compared with the boiler piping and the installation of radiators, seem insignificant.

VIDEO: Economical air heating of a private house

Heat generators, and other miscellaneous units, both purchased and made by hand. In this article, we will consider in detail the air heating of the house and interior.

The air of the rooms received heat from those heated by the passing air and, one might say, indirectly. Such a system was called direct-flow, and had a rather modest efficiency. The reason for that is a large number of heat was spent on heating the entire depth of the floor and walls, as well as on the “heating” of the street. After all, there was still warm air flowing out into the street. But it was precisely because of this difference in temperatures outside and inside the system that a draft was formed that improved the heating process.

Air heating recirculation

Start of application natural gas as a new type of fuel produced in heating air methods real revolution. Air heating with a sufficiently pure type of fuel, the appearance of special air filters - all this made it possible to pump hot air mass indoors, creating closed loop air circulation in the building.


The air flow, heated by electric or, is supplied through specially equipped air ducts to upper part buildings.

The air gives off heat and gradually begins to sink down, returning back to the heater, and it is occupied by other, hotter rising flows.

Such a device of the recirculation system is called gravitational, since the movement of air occurs only due to natural gravity, without the use of any devices. In the event that the structure of the building does not allow air to turn around freely, a forced ventilation system is arranged.

To force the heated air into the premises, and take it back to the heater, take place by means of special fans. Such heating with recirculation is a fairly inexpensive and simple heating option, perfect for warehouses, workshops and other non-residential premises. Why non-residential? The fact is that, passing many times through the heating element, the air loses its quality.

Therefore, when heating an apartment or house according to this type, the air will have to be ionized and moistened. The exhaust air is gradually expelled to the outside, and its place is taken by fresh, from the street. There are also all kinds of combined air/oil or air/water heating systems used for district heating of a small complex of buildings.


Private house: how to make air heating?

First of all, you need to think about everything, and choose the most important thing - a heating element for the system. Very often, special gas generators are used to heat residential buildings and apartments. Which heater model do you prefer?

The correct choice is made taking into account the area of ​​\u200b\u200bthe room, as well as the standard fuel consumption of the unit.
