Heating of the cottage with bottled liquefied gas. The use of gas boilers on bottled gas. Heating your own home with liquefied gas

Natural gas is currently the most optimal fuel for home heating. The only negative is that it is not always possible to connect the heating system to the main gas pipeline. In this case, you can pay attention to an alternative in the form of liquefied gas - boilers using bottled gas in our country are not uncommon.

Classification

Boilers operating on liquefied gas are single-circuit and double-circuit. A single-circuit boiler is intended only for heating, while a double-circuit boiler is capable of both heating the house and providing hot water in it.

Consumers are offered wall-mounted, with open and closed combustion chambers. In addition, you should pay attention to the power of this heater. A variety of modifications often makes it difficult for the user to choose, so it is worth dwelling in more detail on the most important characteristics.

For boilers operating on liquefied gas, the ability to operate at low pressure is of fundamental importance.

The constant supply of bottled gas will be carried out at a pressure of 3-4 Mbar. Therefore, you should pay attention to this parameter.

efficiency

Efficiency is one of the most important parameters of a heating system. Liquefied gas is more expensive than trunk gas, and transportation costs must be added to its cost.

The efficiency of modern serviceable equipment can reach 90-95%. To calculate the gas consumption for heating, you need to know the total area of \u200b\u200bthe room: approximately 1 kW of power is consumed per 10 sq.m.

For heating and heating water in a country house of 100 sq.m, about 2 cylinders per week and 8-9 cylinders per month will be required. You can connect the cylinders in a group: according to the rules, the use of a system of cylinders up to 15 pcs is allowed. In this case, gas containers must be in a closed metal cabinet.

Mounting equipment

To install the heating system you will need:

burner for liquefied (balloon) gas and gas cylinders themselves;
valves and reducers.

Bottled gas burners differ in their configuration from conventional ones, and are usually included as standard with gas boilers. If necessary, they can be purchased separately. Shut-off valves and the necessary gearboxes can be purchased from the company or directly at cylinder filling stations.

Connection

A cylinder or a group of cylinders is connected to the boiler through a reducer with a throughput of about 2 m3 / hour. Reducers for domestic stoves are designed for lower throughput - they are not suitable for the heating system. The gas tank system can have one common reducer or a separate regulator for each cylinder. The second option is more expensive, but it is recommended by the masters - separate gearboxes provide maximum safety.

Cylinders of liquefied gas cannot be installed outdoors: the cold will provoke a decrease in pressure, and the heating pad may refuse to work. The ideal place for installation is a warm, ventilated room. It is important to remember that bottled gas is heavier than air, and in the event of a leak, it will accumulate at the bottom, increasing the likelihood of an explosion. Therefore, the room should be chosen separately from the living rooms. It should not have basements and subfloors!

Gas cylinders are connected to the boiler burner using a metal corrugated pipe - this reduces the likelihood of gas leaks due to system vibrations.

With the help of automatic sensors and the right settings, you can reduce propane consumption rates by 3-4 times. If we are talking about a country house, then gas consumption will be even lower: for the period of absence of people, automation will maintain the temperature at 6-9 ° C, which will reduce propane consumption to 0.7-0.8 cylinders per week. Heating a building with liquefied gas is not the cheapest option, but in some cases it is the most optimal if there is no problem with the delivery of cylinders.

The gas boiler perfectly performs its functions when connected to the main gas pipeline. In this case, it is quite easy to switch the equipment to a constant source of fuel supply - just change the burner.

But if there are no prospects for connecting the building to the gas pipeline, the feasibility should be recalculated. For a house with a total area of more than 100 m2 and maintaining a temperature of about 25 ° C, it is worth considering installing a solid fuel boiler or other heat generator and water heating.

Refueling

Cylinders undergo mandatory certification every 3 years - this is necessary for the user's own safety. Such containers can serve for about 10 years. A standard house consumes about 10-12 cylinders per month, so they will have to be refueled weekly - it is impossible to transport more than 3 cylinders at a time without special permission.

Before refueling, the vessels must be prepared. To do this, you need to remove the condensate, which artificially reduces the usable volume and harms the steel walls. Removing condensate is the prerogative of specialists; doing such work with your own hands is always a risk. If for some reason it is difficult to find a master, then you will have to carry out the procedure yourself. The cylinder is taken out to an open space without sources of fire, grounded and then the gearbox is removed. Leave for 2 hours so that the remaining gas disappears. After two hours of inactivity, the vessel turns over, and the water flows into the ground. You can take it to a gas station.

It is worth choosing a refueller who organizes both transportation and a guarantee for work. It is better not to contact car stations, because their equipment does not have a special cut-off valve that regulates the filling of household gas cylinders with gas. They also do not have a special connector for connecting the cylinder to the station equipment.

Heating a private house with gas cylinders is a necessary measure in the absence of a main gas pipeline. This heating method is often chosen for country houses and summer cottages with an area of up to 70-100 sq.m. In order to save gas, the building is insulated as much as possible, and the gas boiler is used in tandem with electrical appliances if electricity is connected.

Liquefied propane gas or mixtures (propane + butane) are used as fuel, depending on the season. After processing natural gas under high pressure, it passes from a gaseous state to a liquid state and is pumped into cylinders. Liquefied hydrocarbon gases in the abbreviated version are called LPG.

For heating with LPG, cylinders with a capacity of 50 liters are used (gas weight in liquid state up to 22 kg). Cylinders are filled to 80% of the volume, because the gas is able to expand with increasing temperature and can rupture the balloon. Also, when developing the contents of the cylinder, complete emptying is not allowed, but only by 90%.

What you need to connect

To install a heating system on gas cylinders, you will need:

Gas boiler equipped with a burner for liquefied gas;
Gas cylinders with a capacity of 50 liters;
Reducers;
Ramp if several cylinders are connected;
Shut-off valves;
Gas pipeline in the form of pipes and hoses for connecting equipment to the system.

When choosing a gas boiler, you should pay attention to models with the lowest operating pressure and high efficiency. Many models of boilers are already equipped to work with natural and liquefied gas. If connection to the main gas pipeline is not expected, then it is better to choose just such a boiler to work on LPG.

Otherwise, additional equipment is purchased: nozzles for the burner or a complete burner for liquefied gas, and in some models a gas valve. The burner of a natural gas boiler is designed for a lower system pressure and has a valve with a large orifice, which can lead to an emergency.

Boiler connection diagram

The cylinders are connected to the system through a special reducer, which converts the gas from a liquid state into a gaseous state for further supply to the boiler.

Note! The gas flow rate through the reducer should be 1.8-2.0 cubic meters per hour; a conventional gas reducer with a flow rate of 0.8 cubic meters per hour is not suitable for this system.

When connecting cylinders to the boiler, two options are used: one common reducer for all cylinders or a separate reducer for each. The latter option is safer, but also more expensive.

Several cylinders can be connected to the gas boiler at once, which allows you to increase the time between their refueling. For this, a ramp is used - a two-arm collector that distributes the capacities of the cylinders into two groups, the main and the reserve.

First, gas is selected from the cylinders of the main group, and when it runs out, the ramp automatically switches the boiler to the reserve group. The moment of switching is accompanied by a signal. After connecting already filled cylinders to the ramp, the boiler automatically switches to work from the main group.

Note! Gas cylinders are installed at a distance of at least 2 m from the boiler, but the best option for their placement is in a separate non-residential premises or an insulated gas cabinet on the north side of the house.

Gas cylinders must not be exposed to direct sunlight.

The wall thickness of the metal pipes of the gas pipeline must be at least 2 mm. In places of passage through the walls, the pipe is placed in a special case and foamed. The boiler is connected to the gas pipeline using a flexible connection, and a rubber-fabric sleeve (durite hose) is used for the reducer.

LPG consumption

To understand how efficient and expedient it is to heat a house with LPG, let's calculate the bottled gas consumption for a house with an area of 100 sq.m. In such a house, according to thermal calculations, it is recommended to install a boiler with a capacity of 10 kW. To obtain 1 kW of heat, the boiler consumes an average of 0.12 kg / hour of gas. Gas consumption for heating the entire area will be 1.2 kg/hour, and 28.8 kg per day. If we take into account that a standard 50 l cylinder contains about 22 kg of gas, then the weekly consumption will be about 9 cylinders, and this is absolutely impractical.

But in this mode, the boiler only works to heat the heating system. The rest of the time, a properly adjusted boiler consumes 3-4 times less gas, i.e. about 8-9 kg of gas per day or approximately half of the cylinder. A week for heating a well-insulated house of 100 square meters. m will need about 3 cylinders of gas. At the same time, the temperature inside the room will be maintained at +22 degrees (at -18-20 degrees outside).

You can increase the efficiency of heating through the use of automation.

Note! A decrease in temperature at night by 6-7 degrees leads to a decrease in gas consumption by 25-30%.

This means that about 2 cylinders will be needed per week to provide such a system with liquefied gas.

In the case of heating a country house, during the absence of the owners, you can set the temperature regime to + 5 + 7 degrees (only to maintain the heating system in working condition). Then the gas consumption per week will generally decrease to 1 cylinder.

With an increase in the heating area, the required number of cylinders is calculated in a proportional ratio.

Gas cylinders in winter

If gas cylinders are outside the house, then in winter at negative temperatures, the pressure of liquefied gas decreases, and the boiler may simply turn off. To prevent this from happening, the cylinders are installed in a special cabinet with good ventilation, insulated with non-combustible materials. Also for this purpose, stand-alone non-residential buildings with minimal heating are suitable. When using cylinders, the following safety precautions must be observed:

It is forbidden to warm gas containers with an open flame;
There should not be a cellar or cellar near the cylinders, since liquefied gas descends when leaking, has no smell and can accumulate to an explosive concentration;
It is advisable to install a gas leak sensor;
Storage of full containers is allowed at a distance of 10 m from the dwelling;
Storage of empty cylinders in the house is prohibited;
Once every 4 years, it is necessary to check the cylinders for integrity and tightness.

Cons of heating with liquefied gas

The main disadvantages of a heating system using gas cylinders:

Inconvenience of periodic refueling of cylinders, especially in the case of self-refueling (there is no delivery of cylinders to the house);
The imperfection of the method for determining the fullness of the cylinder - by weighing;
High gas consumption with an incorrectly adjusted system and, accordingly, a decrease in its efficiency;
It is not always possible to create the necessary conditions for the installation of cylinders - stopping the operation of the boiler at low temperatures;

How can such a system be used?

This heating method is often chosen if electricity is not supplied to the house, but in the future it is planned to connect to the main gas pipeline. Then there is no need to buy two boilers, and buying a gas boiler will justify itself - it will be enough to transfer it from operation on liquefied gas to normal mode. Sometimes liquefied gas boilers are used simultaneously with electrical equipment or underfloor heating systems in order to save money.

When choosing a heating system for LPG, the area of \u200b\u200bthe house and the degree of its thermal insulation are necessarily taken into account. The optimal heating area with such a system is up to 100-150 square meters. m, and at home with high-quality thermal insulation and the absence of gaps. Heating area over 150-200 sq. m is already becoming inefficient and requires regular refueling of too many gas cylinders.

Urban residents are actively building dachas and country houses, mastering the territories adjacent to the settlement. The areas where the gas pipeline does not pass are not an exception. In the absence of supply lines and a centralized supply of hot water, property owners decide to connect gas boilers for heating from a cylinder. The use of liquefied gas allows you to heat houses and produce water heating. Consider the connection features, evaluate the advantages and disadvantages of balloon heating.

Is it possible to connect gas boilers for heating from a cylinder

When thinking about whether it is allowed to produce heating with a gas boiler from a cylinder, you need to know that the design features of most heating units make it possible for them to operate on various types of gas:

main, which is supplied through the lines of centralized gas supply;
bottled propane, which can be pumped into containers of various sizes.

Due to the fact that in the state of delivery the main part of the heating units is designed to operate on mains fuel, it is necessary to perform one of the types of work related to the conversion:

replace injectors;
dismantle the burner.

After the conversion, all types of heating devices will be able to operate on liquefied fuel, regardless of their heat output and combustion chamber design:

single-circuit and double-circuit;
mounted and floor.

When choosing a gas boiler for heating from a gas cylinder, pay attention to the following points:

the feasibility of using units with reduced operating pressure, which will allow the use of liquefied bottled gas with the maximum degree of efficiency;
the use of devices with increased efficiency, providing efficient fuel combustion at minimal cost.

Having answered the question in the affirmative about the possibility of connecting heating devices to tanks, we will dwell on them in more detail.

Bottled gas is the main power source

Metal containers intended for the storage of pressurized liquefied gas differ from other types of containers:

volume, which is 5, 12, 27 and 40 liters;
degree of filling, which should not exceed 85%;
adapter design;
in red, indicating an explosive hazard.

Filling with various types of gas is possible:

propane;
butane;
a mixture of propane and butane.

Carrying out gas heating of the dacha with cylinders, the latter option is used.

The fuel in the gaseous state, which occupies an increased volume, is liquefied in a special way. During compression, the gaseous fraction becomes liquid, which makes it possible to fill the container with a gaseous substance in an increased volume. In order to prevent a fire hazard, it is forbidden to connect cylinders directly to consumers without using a special reducer.

To feed the boiler with liquefied propane, it is necessary to prepare:

reducer designed to reduce pressure;
shut-off valves that allow you to shut off the supply lines;
pipes that combine individual elements into a common system.

When using bottled gas, special attention must be paid to compliance with fire safety rules.

The main advantages of bottled gas:

ecological cleanliness;
autonomy;
ease of operation;
pressure constancy.

The main disadvantages of using household containers:

insufficient volume;
the need for periodic refueling.

Reducing the number of trips to update tanks will allow the connection of a group of tanks with a common network. Let's dwell on this moment in more detail.

Features of connecting reserve cylinders

During the operation of a gas-balloon heating system, situations arise when the gas supply is interrupted at night, and heating stops. This gives residents a lot of inconvenience, since it is necessary to regularly monitor the filling of containers.

It is possible to make a group connection of the heating device using a special ramp. The design features of the ramp allow you to combine up to ten backup power tanks. How the ramp works:

tanks are divided into separate groups, each of which is equipped with its own pressure regulator;
the working group of cylinders supplies gas to the line supplying the heating unit;
switching to backup power is carried out automatically after the end of gas in the main tanks with automatic signaling;
automatic switching to work from the main group is carried out after full refueling.

Using a group layout allows you to increase the time interval between refueling. Various connection options are possible:

a common reduction gear, which is mounted on the output line;
individual device installed on each container.

Despite the increased costs, the second option is safer.

How to perform heating with a gas boiler from a propane cylinder

It is important to correctly connect the heating system to the tank, while ensuring that safety requirements are met. It is necessary to use a reducer corresponding in performance:

a device designed for a gas flow rate of up to 2 m3 / h can be used to supply liquefied gas;
a reducer with a capacity of up to 1 m3/h, designed for stoves, cannot be used for heating.

Pay attention to the following points:

availability of free access to tanks with liquefied gas for maintenance;
inadmissibility of gasification of premises located in the basement or basement of the building;
maintaining the distance from the tank to the boiler or stove, which should be more than 100 cm;
the maximum volume of tanks, which for residential premises should not exceed 55 liters;
vertical arrangement of containers that must not be used in an inclined position or lying down;
a metal box with tanks should be closed and located in a safe place;
the diameter of the corrugated hoses or copper pipes, which, if larger than 2 cm, will ensure the gas supply at the maximum performance of the unit;
the use of a purchased unit for connecting tanks equipped with a pressure gauge will allow you to control the pressure and check the presence of gas.

The implementation of measures to connect the heating system should be entrusted to professionals who have undergone special training and are licensed to perform explosive work.

Is it allowed to install filled cylinders in the boiler room

The current regulatory documents on fire safety regulate the rules for installing liquefied gas tanks. Norms prohibit placing them in a common room with boilers.

Main requirements:

it is allowed to install tanks in a nearby room or outside the building in a special metal box;
storage of empty containers should be carried out outdoors, however, it is better to fill the containers on time;
to prevent freezing of containers installed in a metal box, it is necessary to use heat-insulating materials that are not subject to combustion;
it is forbidden to heat containers with frozen gas using an open flame;
storage of stocks is allowed only in a ventilated room in which there are no pits;
it is necessary to check the tightness of the tanks at intervals of four years during the certification process.

Remember that compared to air, propane is a heavier gas that, when leaked, concentrates in basements and pits. When a critical concentration is reached, an explosive situation is possible.

Is it necessary to readjust a gas boiler for heating from a gas cylinder

There is no need to reconfigure the heating device if it is correctly converted and connected in accordance with all requirements. Mandatory conditions for operation:

installation of additional elements designed to maintain a constant gas pressure;
the possibility of stable operation of the heating unit when the gas pressure drops to 4 mbar.

You should read in detail the technical description and operating manual of the boiler, which indicates the possibility of operating on liquefied fuel and regulates the value of the operating pressure.

How to provide gas heating of a summer residence with cylinders

The process of switching the boiler to a liquefied type of fuel involves the following operations:

installation of a gas burner and dismantling of dosing nozzles. This will ensure the functioning of the boiler at reduced pressure, which corresponds to the balloon;
reduction gear assembly. The device allows to reduce the outlet pressure of the substance during the transition to the gaseous state;
checking the operation of the gas valve. A number of heating devices need to be replaced by the specified unit when switching to bottled gas.

Switching work is carried out only by representatives of specialized organizations.

Methodology for calculating the volume and need for cylinders for the boiler

the amount of gas contained in one tank allows heating a room of 50 square meters for a week. m;
the average consumption by the boiler of "blue fuel", spent on the production of 1 kW of heat, is 120 grams per hour.

Given the area of \u200b\u200bthe heated room, you can easily perform a simple calculation. For example, for a house of 150 sq. m weekly will require 3 propane tanks of 40 liters. Multiplying the obtained value by 4 weeks, we get the need for a month - 12 pieces. For uninterrupted operation, 6-8 tanks can be connected simultaneously in two groups of 3-4 in each.

Equipping the heating system with automation elements will reduce gas consumption by controlling the temperature at night. With occasional residence, for example, only on weekends, a significantly smaller amount of fuel will be required, which will significantly reduce its consumption.

Heating with a gas boiler from a cylinder - the pros and cons

The main advantages of an autonomous heating system connected to balloon tanks:

fast and simplified connection;
no need to issue a launch permit;
the possibility of installation without project documentation;
independence from centralized fuel supply systems.

Along with the positive aspects, there are certain disadvantages:

the need to use a ramp to connect to the system;
the need for regular monitoring of the availability of "blue fuel";
increased costs for maintaining a comfortable temperature;
additional costs for re-equipment of the boiler;
involvement of specialists to combine tanks into a network and replace the burner.

Despite a number of disadvantages, gas heating of a summer residence with cylinders is an alternative option in the absence of a centralized gas supply.

findings

Individual heating systems powered by liquefied fuel allow you to maintain a comfortable temperature at any time of the year. When deciding to switch to bottled gas, it is necessary to carefully analyze the pros and cons of this heating system. Using the services of specialists, you can safely connect and quickly put the equipment into operation.

To create a well-functioning piping of the heating system of a private house, as a rule, gas boilers are used. Compared to alternative heating devices, they are the most cost-effective and easy to operate. But what about those who do not have the opportunity to connect a private house to a centralized gas pipeline? In this article, you will learn whether it is possible to heat a house with gas from cylinders and how to properly set up safe heating with gas cylinders.

What is more profitable - to use a convector or a balloon?

Until recently, all experts unanimously argued that heating with gas cylinders in a private house is a prohibited way to warm up a home. And all because it carries a danger to the health and life of people living in a room heated in this way. Today, thanks to many years of attempts to introduce this version of the heating system, the opinion of experts has changed. The main thing is to properly tie the heating circuit.

According to expert estimates, as of today, heating a country house with bottled gas is becoming more and more popular. In addition, qualified specialists recommend equipping individual rooms with special convectors. So, in a matter of minutes, they can warm up the air in the room due to the appearance of gas combustion products. As a rule, most models of gas convectors have compact overall dimensions and are resistant to freezing.

Thanks to innovative technologies, manufacturers of heating equipment offer potential consumers the widest range of units that operate using liquefied gas. This option is not much different from equipment that is identical in functionality, for example, water boilers. However, there are some subtleties: you will have to regularly monitor the amount of gas in the vessel. When using two boilers at once, you can in some sense insure yourself, thereby eliminating the need for constant checks of cylinders to control the volume of fuel resources.

The use of electric convectors for heating a private house, although it is faster, is less comfortable and more expensive in everyday life.

Proper storage is the key to safety

To avoid emergency situations when using gas cylinders for heating a private house, it is necessary to adhere to a number of recommendations:

Gas cylinders are placed away from the gas stove at a distance of at least 50 cm. Whereas the minimum distance between liquefied gas tanks and heating radiators should be 100 cm.
Gas cylinders for heating are stored outside. To avoid direct sunlight and climatic precipitation on fuel containers, it is necessary to reliably protect it, placing it, for example, in a metal sealed cabinet. In addition, there are special safes for storing such items, which you can easily purchase at any specialized store.

For the winter, the box where the cylinder is stored is insulated with mineral wool, rags, sand, etc. The main task is to avoid freezing of the container, otherwise the entire heating system will stop, the coolant in the pipes will freeze, which can lead to a rupture of the line.

When using liquefied gas in cylinders for home heating, give preference only to those containers that have successfully passed the suitability test.
The residual pressure should not exceed 0.05 MPa.
The gas cylinder must not have mechanical damage and deformation.

Gas cylinders with slight corrosion damage on their surface are not suitable for use!

When storing gas cylinders indoors, special attention should be paid to temperature conditions. So, it is strictly forbidden to operate such containers at temperatures above 45 ° C.

By adhering to these rules, you will not only be able to keep the heating system intact, but also protect yourself and your loved ones by ensuring their safety. It is strictly forbidden to neglect such recommendations for storing gas cylinders!

Advantages of gas-balloon heating

Gas-balloon heating of a private house is a financially profitable investment. And all because in such vessels there is liquefied natural gas. It is able to literally change its state in a few seconds and transform into a gaseous state. In addition, it has a high efficiency compared to other, more expensive fuels. And this is a decisive factor in the choice of energy resources.

If you are planning to equip your home with autonomous heating with bottled gas, then believe me, in this case it will be truly autonomous. This is directly related to the fact that vessels with fuel can be transported from place to place without any problems. And even outside of civilization, this heating option will be an excellent way to create comfortable temperature conditions in the house.

In addition, using gas cylinders for heating your home, you not only heat the room, but you can also use hot water at any time, which circulates through the heating main. For this reason, heating on gas cylinders is an indispensable and most profitable way to equip a thermal block in rooms where it is not possible to use any other alternative type of fuel. And besides, it can rightfully be considered an independent heating method, since the availability of fuel resources depends solely on you and your reserves.

As of today, propane (propane-butane) is considered the most common fuel for heating country houses. Such systems are environmentally friendly, they are easy to operate and maintain, economical in financial costs, and stable (pressure drops in the system are not observed).

Regardless of what type of energy resources you used before, firewood, gas, coal, at any time you have the opportunity to switch to such a heating system.

And if you read reviews about heating a country house with liquefied gas, you will surely make sure that this option is indispensable for the construction of both country houses and residential private buildings.

Disadvantages of heating with liquefied gas

Like any other heating system, the use of gas cylinders as a fuel for space heating has a number of disadvantages. And if you want to equip your home with just such a thermal unit, then it will not be superfluous if you study the negative aspects of this issue.

The very first disadvantage of such systems is the instability of the cost of fuel. So, in one region, gas will have one price, while in another it will be somewhat different.

Purchase gas only from trusted suppliers. Otherwise, the risk of reducing the efficiency of the heating unit from low-quality fuel is very high.

In addition, liquefied gas is an explosive substance. Therefore, follow the rules for the installation and operation of containers with this type of fuel.

Secure storage

And at the end of this publication, I would like to add: if you heat your home with a gas-cylinder installation, then do not neglect any advice given to you by professionals when buying containers for this fuel. If you adhere to the set of rules presented in our publication and do not violate them, then the heating unit will work efficiently and smoothly. In addition, the consumption of fuel resources for heating your home will be minimal, and you will be able to protect yourself from emergencies.

VIDEO: Autonomous gasification system from propane cylinders (standard 50 liters)

It often happens that it is not possible to connect a building to centralized heating. If the owner, having gone through all the options, stops at such a heating method as liquefied gas, you should take into account all the nuances, calculate the consumption of liquefied gas for heating the house and weigh whether this method of heating the home is rational.

What is liquefied gas

Liquefied gas is natural gas that has changed its state of aggregation and turned into a liquid, significantly decreasing in volume. The transition requires low pressure and normal temperature. As a result, a much larger volume of fuel is placed in gas storage tanks.

Cylinders are filled with a mixture of propane and butane, which remains liquid under high pressure. This makes transport easier and safer. There are three options for the fuel that cylinders are filled with, depending on seasonality:

technical butane;
technical mixture of propane and butane (summer version);
technical mixture of propane and butane (winter version).

In order not to face the problem of the impossibility of heating in the winter due to high frosts, it is necessary to insulate the boxes where the cylinders are stored and equip them with a heater. At low temperatures, the gas does not freeze, but turns into a liquid, and does not enter the heating system. This is due to the boiling of the mixture at a temperature of ten degrees below zero, the pressure drops. To prevent this from happening, in addition to insulation and heating during outdoor installation of cylinders, airflow from the boiler room through specially made air vents is provided.

Safe use of LPG at home

LPG mixture is much heavier than air. And if there is a gas leak from the cylinders, it always collects above the floor surface, and you can already feel the presence of gas in the room when it reaches a critical explosive level. For this reason, the gas cylinder should only be installed outdoors, in a special metal compartment in a vertical position. The device must be equipped with holes for ventilation.

in case of freezing, it is forbidden to heat the cylinder with electrical appliances, heating elements;
structures with a balloon installation are located on the outside of the dwelling and preferably on the north side, to exclude sunlight;
the cylinder is filled with less than eighty percent of its volume, the remaining percent of the space is given for expansion;
systematically check cylinders for leakage;
gas pipelines must be made of reliable and powerful materials.

Liquefied gas for home heating

The presence of gas cylinders with propane - butane in country dwellings no longer surprises anyone. People where gas is not connected actively use this option in the kitchen, for conservation, cooking. But recently, more and more often you can hear that country houses are heated with liquefied hydrocarbon gas, LPG. Recently, the purchase of equipment and installation of a heating system has become quite affordable for the general population. More and more people who do not have the opportunity to receive centralized gas for heating are installing equipment for heating with liquefied gas.

Among the advantages of this option for using liquefied gas, the following features stand out:

the ability to make independent autonomous heating in a place where it is impossible to use centralized heating;
gas can be used all year round;
the system is of high quality and reliable operation;
the gas tank is a small and visually invisible reservoir, does not take up space, as it is located underground;
ease of delivery of raw materials that does not require the construction of a pipeline;
liquefied gas has a higher heat capacity than natural;
raw materials are considered environmentally friendly;
compared to other heating options, the low cost of gas, not dependent on fluctuations in the cost of natural.

But we can not say about the disadvantages of using liquefied gas:

provided that the dwelling is located far from the city, the cost of raw materials may be increased due to travel costs;
at high frosts when using liquefied gas, there is a danger of freezing of the gas reducer;
due to bad weather conditions, roads can be swept up, making it difficult to bring in a new supply of fuel;
it is permissible to design and install an autonomous heating installation on liquefied gas only to qualified specialists who own the issue; only the simplest units can be made independently.

Features of heating a residential building using liquefied gas

One of the main inconveniences is that the owner must constantly monitor the gas level, monitor stocks and replenish them on time. Independence from the central gas supply and complete autonomy is considered an advantage for some, a disadvantage for others. But with responsible control of the level of stocks, there will never be problems and interruptions in heating.

A fifty-liter cylinder is filled with liquefied gas and serves as fuel for heating small-sized cottages, cottages and houses. Every few days, changing an empty cylinder to a full one is rather inconvenient, so experts advise connecting several cylinders into a battery and looping them. When mounting a heating system with liquefied gas on your own, it is permissible to make a battery of three cylinders. If you want to combine a larger number, you need to prepare a project and documents.

Gas cylinders must not be installed indoors. They are located only on the outside of the house in a special metal cabinet. In frosty weather, there are cases of freezing of the gearbox or condensation, which makes it difficult to supply gas. To avoid such inconvenience, a small electric heater is installed in the closet.

Heating with liquefied gas is especially convenient if the area of \u200b\u200bthe building is not very large and there is confidence that there will be no problems with access to raw materials. If this moment is a big question, it would be better to purchase a gas tank. This is such a large bunker for liquefied gas filling and storage, such a tank is filled once every two to three years. The volume of the tank may vary. The owner selects it according to his needs: from three to ten cubic meters. The gas tank can be placed at a distance of at least ten meters from the dwelling, and a convenient road - an entrance - should be equipped to the tank.

Consumption of liquefied gas for home heating

The most important question that worries the future user of such a heating system is: “Is gas-balloon heating rational?”. On the one hand, not many items are needed to build a heating system and it seems very simple. Is it really? To build a heating system with liquefied gas, you will need:

buy a special gas boiler that can operate on raw materials such as gas-balloon raw materials or independently rebuild the control system and replace nozzles;
buy fittings, reducer and gas-balloon equipment;
connect all the mechanisms and set up the heating system.

The question of the amount of gas that is spent on heating the house and the ability to warm up the entire cubic capacity of the dwelling is one that needs to be calculated in advance. As can be seen from the feedback from users of such a system, provided that the house is not sufficiently insulated and the total area is over two hundred square meters, it is better not to start mounting such a heating system. It will be unreasonably expensive. In this case, you should switch to solid fuel boilers.

Heating your own home with liquefied gas

Heating a country house with liquefied gas is an excellent option for residents of remote settlements, where it is very expensive or even impossible to supply gas. In this case, the use of liquefied gas for home heating is an excellent solution. User reviews claim that this kind of heating is an alternative to any other, and even to the once popular diesel fuel. Gas holders located on the territory of the yard provide uninterrupted gas supply. When installing the tank, it is important to take into account the requirements for the required distance from the house - at least ten meters and the distance to communications - no closer than two meters. The capacity is selected taking into account the individual needs of the dwelling and the boiler. In private buildings, when using liquefied gas during the heating period, boilers with a capacity of up to ninety kilowatts are installed, the storage capacity ranges from three to nine cubic meters. Replenishment of stocks in the storage is carried out at the expense of a special machine that delivers liquefied gas as needed.

Liquefied gas is recognized as an economical type of fuel. It is relatively inexpensive to heat a room of a sufficiently large area.

For example, to heat an area of two hundred square meters, you need to purchase a boiler with a capacity of twenty kilowatts. For such a unit, you will need a five-cube gas tank that requires refueling, depending on the temperature regime, no more than once a year.

The sequence of organizing heating with liquefied gas

It must be understood that it is impossible to do the work of mounting the heating system on your own, without special education and experience. All these stages: design, installation, installation of a gas tank, connection of related equipment, should be carried out only by masters. It will not be superfluous to check their permits and licenses to carry out this kind of work. It is not difficult to find specialists in the installation of autonomous gas supply, at present there are many offers from companies capable of creating a gas supply and heating system.

When installing gas supply, follow the instructions that guarantee the reliability, safety and high-quality operation of the heating system:

preparation of project documentation - the first stage, during which a decision is made on the type of system, pricing policy, performance, power and other parameters are calculated;
purchase of equipment - there have been no problems with the purchase of equipment for a long time, gas equipment for autonomous heating offers a large number of companies, and you can choose an option based on the price, video guides on the operation of the equipment are offered, which helps to make a purchase decision;
installation and work on starting the heating system - the performance of this work by professionals guarantees the smooth and efficient functioning of the equipment for a long period of time;
filling the system with liquefied gas;
maintenance of technology.

If there is no desire or opportunity to install a gas tank, then heating is done using cylinders combined into a battery. This is the same heating, but the boiler will not work from the storage tank, but directly from the cylinders. For small buildings, cottages and summer cottages, this is a suitable option, since it is not always possible to locate a storage facility in a small area, taking into account the required distances from the reservoir to your own and neighboring buildings.

Consumption of liquefied gas for heating a house 100m2 and 150m2

It is an undeniable fact that the better the house is insulated, the lower the gas consumption. It is necessary to insulate all problem areas: the attic, windows, floors and walls. If we talk about heat loss through these sections, then heat loss schematically looks like this:

thirty-five percent of heat is lost through the roof;
at least twenty-five percent of the heat is lost through the attic;
twenty-five percent of the heat escapes through uninsulated windows;
ten percent comes out through the door;
the floor impoverishes the room by ten percent.

You can calculate the fuel using the formula. To find the desired amount of gas, you need to divide the heating power by the minimum specific heat in kilowatts and multiply by the efficiency of the boiler. Experts have calculated the cost of different types of fuel when heating a house with an area of one hundred square meters for six months. It does not make sense to give numbers, since the prices for everything change, but among all the options:

main gas;
pellets;
coal;
firewood;
bottled gas;
diesel fuel;
electricity.

The leader in terms of cost, that is, the most expensive, turned out to be heating with the help of electricity and diesel fuel. The cheapest option is centralized gas heating, which, unfortunately, is not always available. That is why we have to look for alternative options, one of which is liquefied gas.

Calculating the consumption of raw materials, use the above formula. The result is considered in kilograms, but the answer is translated into liters. Then we multiply by the number of days that the heating will work. If we take the average boiler efficiency of ninety-two percent, then a house of one hundred square meters will need about five hundred and seventy liters. As for a dwelling with a cubic capacity of one hundred and fifty square meters, the consumption is not less than eight hundred and forty liters. The cylinder that is used is usually forty-two liters of gas. Dividing the amount of gas required for heating by the amount of gas in the cylinder, that is, forty-two, we get the number of cylinders. And already when multiplying the result by the cost of liquefied bottled gas, we find out the amount needed to heat the home throughout the season.

Heating a house with liquefied gas in cylinders, reviews

Reviews that heat their home with liquefied gas agree on one thing - the home must be insulated so that there is no gas overrun. Consumption depended on weather conditions, and on the cubic capacity of the house.

A well-insulated dwelling with an area of one hundred and fifty square meters, at a fixed set temperature of twenty-three degrees, required the following amount of raw materials for heating with liquefied gas cylinders:

at air temperatures from zero to five above zero, four cylinders were needed - November;
at temperatures from minus ten to minus twenty-eight, ten cylinders were used up - December;
at temperatures from five to twenty below zero, eight cylinders were used up - January;
at temperatures from five to fifteen below zero, seven cylinders were spent;
with a run-up in temperature from five degrees below zero to five degrees above 0, six cylinders were needed.

As you can see, during the heating season of five months, the user used up thirty-five cylinders.

LPG heating efficiency is high in the absence of other sources. Each region has its own priority fuel or heating option, depending on the climate, the availability of one or another option. The discussion about the fact that some kind is cheaper and more priority is unreasonable.

If you do not install a gas tank, then you should take into account the fact that gas cylinders will have to be taken to a gas station, which will entail additional financial and time costs.

Experts insist that heating with liquefied gas will be beneficial under the following conditions:

the dwelling does not have a very large area - about a hundred squares;
the house must be insulated with high quality;
heating with this type of raw material is temporary and in the future it is planned to connect to a centralized gas system, in which case you will not have to spend money on buying an additional boiler;
there is a backup option for heating, which, in the event of unforeseen situations, will help to cope with the problem of heating the home.

If the cylinders operate in isolation, without being connected to a battery, it is necessary to have at least three pieces: one for the operation of the boiler plant, the second for changing, and the third as a reserve in case of unforeseen circumstances.

Heating with liquefied gas is a convenient and affordable option when it is impossible to use centralized gas. All recommendations and safety precautions must be followed. In this case, your home will always be warm and cozy.
