Installation of gas heating for a private house. Heating system in a private house: diagram from a gas boiler

20.10.2023

The most economical heating resource today is natural gas. In addition, it is the most affordable. That is why the most optimal option for installing a heating system in a private house is gas heating of a private house. Even if the energy supply is not possible, there are alternative options (gas cylinders, gas holder).

Gas is the most popular heating resource

And if there is a gas main in the area, then the installation of gas heating for a private house is greatly simplified. There are several optimal schemes for heating private houses with gas. One of the excellent options for permanent use in a private home is a gas boiler.

How to choose a gas boiler

Gas boilers differ depending on different indicators. By power they are: low power (up to 65 kW), medium (up to 1700 kW) and high power (up to 15000 kW). Low and medium power are perfect for heating a residential private house. High power boilers are usually used in industrial facilities.

In terms of functionality, gas boilers can be single-circuit or double-circuit.

Single-circuit boilers are intended only for use in heating systems. Double-circuit boilers are also designed to heat water in CO and the needs of residents. Double-circuit boilers can be of the flow-through type. Such boilers are used only when the volume of hot water consumed is insignificant. Double-circuit boilers with a built-in boiler provide full heating in a private house with gas and a supply of hot water. There are also boilers for maintaining the temperature of water in swimming pools, etc. (in this case, these are specialized solutions).

Burners in gas boilers can be atmospheric or ventilated. Atmospheric burners are the most common option for heating private homes. Ventilation burners are usually used in industrial facilities.

According to the type of draft, boilers are available with natural draft (there must be a chimney) and with forced draft (gases are removed using a fan).

Depending on the installation method, boilers used in the gas heating system of a private home can be floor-mounted or wall-mounted. Floor-standing boilers have higher power and are larger in size. They are also more durable and their cost is slightly higher. Wall-mounted gas boilers are relatively inexpensive appliances; they are compact and have lower power. Also, wall-mounted boilers are less durable.

Water gas heating system for a private house

The most common heating system is water: the role of heat carrier is played by water, which circulates through a closed pipeline circuit. The water is heated in the boiler and then transfers heat through pipes and heating radiators (batteries).

Such a gas heating system for a private house has several advantages:

water is an effective coolant;
the circulation system is closed, so after the initial filling the volume of water should not change;
water gas heating of a private house, the video, which can be viewed below, will show that such a system can be installed independently;
in such a system it is easy to create a circuit that ensures uniform heat supply to each room.

Among the disadvantages of a water gas heating system:

Heating radiators must be kept clean at all times, since if they are covered with dust, the efficiency of heating the premises will be lower;
in comparison with air heating, water heating, after switching on, will not be able to provide the same rapid heating of the air;
elements that are part of a water heating system can often crack, corrode, etc. This can not only worsen the microclimate in the house, but also cause damage to the interior of the premises;
there are special requirements for the quality of the heat carrier: the amount of salts in the water must be minimized;
The heating cannot simply be turned off in winter, when it is very cold outside, as this can lead to freezing of water, which will increase in volume and burst the pipes. Therefore, gas heating of private houses of this type is not suitable for dachas where the owners do not visit often, especially in winter.

Heating schemes for a private house

Depending on how the coolant circulates inside a closed loop, there are CO with natural and forced circulation. In the first case, circulation occurs due to the difference in density of cold and hot water, and in the second case, the pump operates. If you want to make a heating system for a private house yourself, then you need to make a careful calculation of the optimal CO scheme.

Heating distribution is an important element in the system. It comes in two types:

single-pipe. It is not often used in private homes, since with such wiring the temperature in the radiators varies. This option is suitable for houses that are small and have few rooms;
two-pipe. This option is quite material-intensive. But the system is suitable for regulating the temperature in individual rooms.

The single-pipe gas heating scheme for a private house has one significant drawback - the lower radiators heat up less, since they receive slightly cooled water. And if you have a two-story private house, then the rooms on different floors will also warm up unevenly. If you want to equip gas heating with your own hands, then this scheme will be much simpler.

In addition, little material is wasted when laying the pipeline. The problem of uneven heating of radiators is solved by installing a jumper and increasing the number of sections. And to circulate the coolant faster, a circulation pump is used.

Note that a natural circulation scheme will be suitable if it is possible to install the boiler below the level of the radiators. Also, for the normal circulation process to occur, a natural slope of the supply and return pipelines is necessary.

As for artificial circulation, the use of a pump is necessary. Such schemes are quite easy to install, but they have several disadvantages. These include the same uneven heating, as well as the appearance of air jams and dependence on the electrical supply.

Very often you can find such an option as the Leningrad wiring of the heating system (Leningradka). The meaning of this system is that water circulates in a pipe closed to the boiler. Heating equipment (radiators) is connected to it, through which the coolant will flow parallel to the supply circuit. The system is quite effective for a private home.

The next scheme is a two-pipe one. In this case, the radiators will heat evenly, but the cost of laying pipes will be higher. The heating of individual heating radiators can be regulated using special shut-off valves.

A two-pipe system with natural circulation and bottom wiring is well suited when the boiler is located in the basement.

Stages of installing a gas heating system in a private house

Gasification of a private home is an important and responsible process. Gas heating equipment includes several stages:

Preparation and approval of design and permitting documents. The gas heating project for a private house should be created by specialists, since this is an important element on which further arrangement depends.
Purchase of necessary equipment and materials.
Inserting a house system into a street gas pipeline.
Installation of gas networks inside the house, arrangement of a special room for a gas boiler.
Installation of gas equipment.
Filling the heating system with coolant.
Test run. It would be better to produce it with working and increased pressure.
Acceptance of the finished system.

Gas heating installation schemes must be thought out to the smallest detail, so projects must be carried out by professionals.

One example of drawing up a professional heating system plan

When choosing equipment for gas heating, remember that the main indicator is the area of the heated room. The volume of equipment, the number of radiators, the footage of pipes, fittings, valves and valves, and plugs depend on it.

When choosing a method for laying heating pipes and installing them, remember that the cold and hot distribution lines must be laid with a slight slope directly towards the hot water flow.

Experts recommend installing taps on each battery. Thanks to this, it will be possible to control the supply of hot water to a separate room of a private house. If you are using an expansion tank of 20 to 30 liters, then it should be installed at a height of 3 meters above the heating boiler.

Conclusion

Gas heating of a private residential home is the most effective and affordable option if there is a highway in the area of your home. In this case, fuel is consumed economically, gas equipment is easy to operate, and you can set up such a system yourself.

Natural gas is constantly becoming more expensive, but gas heating still remains the most popular option for heating a private home. The main reasons: efficiency, ease of use and reliability of power supply - the pipe is closed much less often than the electricity is turned off. The price of fuel depends on the country and region of residence.

To make a gas heating system for a country cottage or summer house, you need to clarify a number of points in advance:

Assess the possibility of connecting main gas or installing a container for a supply of propane-butane mixture - a gas holder.
Select a heat source designed to burn gaseous fuel.
Develop a scheme for efficient heating of rooms.

Methods of gasification of a residential building

There are 3 options for supplying natural gas for heating needs:

connect to the nearest highway;
install an underground (ground) gas tank in the local area and install a fuel supply pipe into the building;
use fuel in cylinders.

Reference. Centralized gas supply networks supply methane, gas tanks and cylinders are filled with a liquefied hydrocarbon mixture (abbreviated as LPG) propane + butane.

Scheme of autonomous gasification of a home from a ramp with propane cylinders

Each of the listed methods has its pros and cons. The simplest and cheapest option is to mount a gas cylinder ramp inside a metal cabinet installed outside the house. Permits and professional installation are not required - all work can be done with your own hands. The problem lies in the operation of the installation:

to properly heat a home for 2-3 days you will need at least 4 cylinders plus two in reserve;
twice a week you will have to refill empty tanks with bottled gas - carry and transport heavy containers;
during transportation you may be stopped and fined by a police officer, the reason is transportation of dangerous pressure vessels in a regular car;
In winter, the cabinet with cylinders must be heated, otherwise the propane will stop evaporating, and electricity costs will be added to the total cost of heating.

Preliminary conclusion. Heating a residential country house using propane cylinders is extremely inconvenient and expensive. This option is suitable for a small dacha, where autonomous heating is turned on periodically, 5-6 days a month.

How to install main gas

The procedure for connecting heating equipment to an external gas network in the post-Soviet countries is approximately the same. If the low pressure line runs close to your home (no further than 200 m), collect the following package of documents:

project documentation - layout of the land plot (with all buildings), building passport;
certificate of ownership;
situational plan - part of the diagram of a populated area with a gas pipeline;
an application in the prescribed form indicating personal data, residential address and other information;
fuel consumption, m³/h.

Calculation example. A two-story house with an area of 200 square meters is planned to be heated by an economical gas boiler with a closed chamber, productivity - 20 kW, efficiency = 92%. Fuel consumption in maximum combustion mode will be V = 20 / (9.2 x 92 / 100) = 2 m³/h.

You submit the collected documents to the customer department of the gas supplier organization. After approval, you are given technical specifications for the connection, which are the basis for designing the external and internal fuel network. You order a project, agree with the service provider and begin installation.

Laying a gas pipeline aboveground (left) and underground (photo on the right)

Important point. If gas equipment for the home can be installed independently, then the laying of pipelines and connection to the main line is carried out only by a specialized company. Upon completion, certificates of completed work and readiness of the facility for operation are drawn up. A detailed description of the procedure is given in the article on the heater.

The cottage heating system, which consumes main gas, is very convenient and profitable to operate (excluding countries where the price of fuel has increased 5-10 times). Now about the disadvantages:

Unreasonably high cost of connecting to a centralized gas supply network. In the Moscow region. In the Russian Federation, the price of the service often reaches 7500 USD. e. (more than 500 thousand rubles), residents of remote regions can meet 1000 USD. e.
Bureaucratic red tape when obtaining permits and concluding contracts.
Dependence on an external source of blue fuel supply. In recent years, users in the CIS countries have noted the supply of low-calorie gas, presumably diluted with nitrogen.

Before installing the gas pipeline, you need to buy a meter, shut-off valves and pipes specified in the project

To install or replace equipment in a gasified home, you must, again, contact Gorgaz - obtain permission and make changes to the project. Setting up individual heating in an apartment in a multi-storey building is an almost impossible mission.

Autonomous heating with liquefied propane

The installation of independent gas heating involves placing an underground or above-ground tank in the area adjacent to the house and laying a supply pipeline. For clarity, we will give a more detailed list of design, construction and installation works:

Important addition. Before installing an LPG tank, you must obtain permission from the district architect and agree in writing on the placement of the tank with your neighbors. A package of documents - a building passport, a site plan, a certificate of ownership and various certificates as required by the architectural department. Unauthorized construction is unacceptable - the facility will not be accepted for operation, and no one will fill the gas tank without permission.

When installing the container, you must maintain the specified distances to the nearest objects

It will not be possible to carry out the entire complex of work with your own hands - you will have to hire a specialized company. The cost of turnkey construction starts from 1500 USD. e., which is comparable to connecting the main methane. What pitfalls await you when choosing a container and paying for installers:

Advice. It is better not to buy overtly cheap gas tanks; such tanks are made from used metal vessels. The service life of a restored tank is 10 years, a new one is at least 25 years.

Don’t rush to sign a tank maintenance contract, since there is nothing to repair or clean, and you will have to pay money. We recommend listening to the opinion in the video:

Conclusion. Both options - heating the house with liquefied and natural gas - are expensive to implement. In terms of operating costs, methane clearly wins, and in terms of autonomy, LPG wins. But if you offer another choice - gas or electric heating, then the latter will clearly lose in terms of the average cost per kilowatt, even taking into account the preferential night tariff.

Choosing heating equipment

To burn gas to heat private houses, 4 types of heat generators are used:

hot water boilers;
gas convectors and fireplaces;
infrared heaters;
heat guns.

From the name it is clear that gas boiler units are designed to work with water heating systems - radiators or heated floors. Infrared devices heat objects and open surfaces, transferring heat to the indoor air. Fireplaces, convectors and fan heaters are purely air units.

Heat gas guns and infrared heating devices are practically not used for full heating of residential buildings. Such equipment is ideal for small country houses and outbuildings - greenhouses, sheds, construction sites and so on. Therefore, we propose to focus on stationary heat sources - boilers and convectors.

Types of water heating devices

Gas boilers can work with any water systems - heated floors, radiators, in-floor convectors and baseboard heaters. In cottages with a large area on 2-4 floors, a more modern solution is often implemented - the device prepares the coolant for air heating units - water fan heaters or fan coils.

According to the principle of operation, boilers are divided into 3 groups:

Atmospheric ones with an open chamber work thanks to the natural draft that occurs in a chimney pipe of a certain height (4...6 meters or more). The air required for combustion is drawn into the furnace from the boiler room; the efficiency of the devices lies in the range of 86...90%.
Turbocharged ones with a closed chamber are more economical. Here, air is forced inside the sealed firebox by a fan connected to a double-walled coaxial chimney. Natural draft is not required, the efficiency of the units reaches 93%.
Condensing heat generators are similar in structure to turbocharged models. The difference lies in the design of the burner and the main cylindrical heat exchanger. In low-temperature mode, the boiler uses the latent heat of combustion of gas, causing efficiency to increase to 96%.

Classification of boilers using natural and liquefied gas

Comment. 99% of all heaters are capable of burning main gas and LPG without loss of efficiency. To do this, it’s enough to replace the burner jets and adjust the automation settings; you don’t need to change anything.

All types of boilers are offered in floor-mounted and wall-mounted versions. Most stationary models operate without an electrical connection, while wall-mounted versions are mini-boiler rooms equipped with a built-in circulation pump and expansion tank. To provide the home with hot water, double-circuit modifications with a flow-through heat exchanger are available.

There are combined versions of heaters designed to use gas, wood and coal, or supplemented with an electric heater. Combining a solid fuel chamber with a gas chamber increases the size and weight of the product, but reduces the efficiency of fuel combustion. Another thing is adding a heating element, which does not take up much space and does not affect the efficiency of the boiler.

Electric-gas (left) and coal-gas heat generator from the Atem brand

Consideration of each type of natural gas heat generators is a rather extensive topic that deserves a separate description. Here we provide several recommendations for choosing a boiler for gas heating of a home:

Take the thermal performance of the unit with a margin of at least 20%. If you plan to heat water for domestic hot water needs, increase the power by 1.5-2 times.
Choose a heat generator according to your financial capabilities. If your house has a chimney, purchase an inexpensive atmospheric boiler; if you don’t have one, buy a supercharged one. Installation of a sandwich chimney is more expensive than a turbocharged model along with a coaxial exhaust gas outlet.
A dual-circuit version of the heater is quite sufficient for one water collection point. To simultaneously use hot water in two bathrooms, it is better to install a single-circuit unit plus.
For a gravity-flow heating system, take a non-volatile floor-standing boiler, for example, a budget option like AGV.
Any wall-mounted heat generator is perfect for working with underfloor heating and a closed-type system. The choice of manufacturer and number of heater functions depends on your budget.
When installing individual heating for a home in an apartment building, choose a wall-mounted turbocharged version of a gas boiler with a coaxial chimney.

Due to their prohibitive price, condensing heat generators continue to be a luxury for the average homeowner. The second negative point is the complex control electronics, which will be expensive in the event of a breakdown, for example, due to power surges.

Application of gas convectors and fireplaces

We have combined these types of heaters because they work approximately the same way - they burn gas and heat room air. In appearance and the method of emission of smoke, the convector resembles a parapet boiler - the device is placed close to the outer wall, the pipe is led out into the street through the building structure. The fireplace will require a traditional chimney.

Reference. Unlike convectors, a gas fireplace emits infrared heat into the room, creating a comfortable atmosphere in the room. In this regard, the unit resembles a classic stove, equipped with a transparent panoramic firebox door.

Features of gas convective heating:

heaters are located in every room except the corridor;
the air temperature is regulated directly on the room heater;
From the outside, pipes with fuel are supplied to the devices, connected to the gas network or LPG tank;
fuel combustion efficiency is in the range of 85...90%;
There are no pipes or batteries inside the home.

A fireplace is an expensive product; such devices cannot be placed in all rooms. A decorative gas fireplace is placed in the living room, serving as a source of warmth and home comfort.

In our opinion, the use of convectors is justified in small houses with 2-3 living rooms. It is better to heat more spacious cottages with boilers. Causes:

A clear disadvantage of air heating devices is the inability to heat the lower zone of the room. An alternative solution - electric heated floors + gas convectors - will be too expensive.

Finally, about water heating schemes

To distribute heat throughout the rooms of a country house, 4 main schemes are used:

two-pipe dead-end;
single-pipe ring, otherwise - “Leningradka”;
collector (radial);
gravity or gravity.

Gravity distribution with natural circulation of water from the boiler, the pump operates when electricity is available

Note. As a rule, the first three circuits are made closed, that is, the system operates under excess pressure. When it is necessary to ensure energy independence of heating, open-type gravity distribution is installed.

The heating scheme for a private house with a gas boiler is the most versatile and easy to install. 2 pipes are laid from the heat source to the batteries - supply and return; if necessary, the system is divided into floor branches, as shown in the figure below.

If you plan to assemble the circuit yourself, definitely use the two-pipe version. Other types of wiring are more difficult to calculate and install correctly. "Leningradka" is limited by the number of radiators; the radial system lines must be laid in the floor. discussed in detail in our other material and described by the master in the video.

There will be no comfort in any home without sufficient heat. It can be provided in different ways, but the most common option is gas. Read about how gas heating should be organized in a private home and what is needed for this in our review today.

Types of gas heating

Depending on the region and gasification conditions in it, you can choose one of three heating methods:

liquefied gas from cylinders;
liquefied gas from a gas tank;
natural fuel from the main pipeline.

The first two are used in non-gasified settlements and differ only in the method of gas supply and storage.

When choosing heating with liquefied gas, check the feasibility of this method. In some areas this may not be cost effective compared to other heating options.

Cylinder liquefied gas is supplied in containers of 50 liters. If this volume in summer is enough to service the stove for more than a month, then in winter, when the heating is turned on, a household cylinder will be of little use; it will need to be changed every 2-7 days, depending on the outside air temperature. A gas holder gas storage system is much more profitable; higher costs will only be incurred at the installation stage. Wholesale purchase of gas during operation is much more profitable than purchasing cylinders.

A gas holder is a sealed gas storage facility with a volume of two thousand liters or more. This amount of gas is enough to heat a country house with an area of 120-150 m² with gas. For a cottage of 300 square meters, where gas consumption is many times higher, you will need a capacity of approximately eight thousand liters. If the village in which your house is located is gasified, then the best option would be to connect to the main line. In this case, gas heating in a private house will be expensive only at the installation stage.

Advantages of gas heating

The advantages of heating a private house with gas are obvious.

Low price of fuel: in our country, “blue” fuel is one of the cheapest (taking into account logistics costs).
Modern gas boilers have high efficiency, allowing for economical fuel consumption.
A large selection of boilers with different capabilities, including heating water for economic and domestic needs.
Ability to heat large areas.
Environmental friendliness.

Flaws

There are also disadvantages to heating a private house with a gas boiler, one way or another they are all related to safety. If you carefully monitor your gas equipment, nothing bad will happen.

How to choose a heating gas boiler

A person who is faced with the problem of choosing a gas boiler for the first time may get confused and confused in the variety of modern models. Where should you start? The first thing you need to pay attention to before purchasing is the power of the device. It should provide heating for the house depending on its area. In this case, you need to purchase a model with a margin of approximately 20% of the required volume. This will be needed to heat the house during particularly cold periods. Next, we will consider the issue of hot water supply. If your home has or plans to install an electric boiler or other water heater, then you need a single-circuit gas boiler.

If you plan to heat water for domestic and household needs through a boiler, purchase a double-circuit model. There are two options to consider here:

A simple flow circuit when the hot water flow is low.
A heating system with a built-in boiler will not only heat the home, but also provide a sufficient amount of hot water.

Modern gas boilers can be designed to operate with natural or artificial draft. In the first case, the installation of additional pipes for exhaust gases and air supply will be required. The second option involves the presence of forced ventilation. Depending on their placement, boilers can be floor-mounted or wall-mounted. Floor-standing boilers are characterized by increased power and large dimensions, often requiring a separate room for their installation. If your private home is small, then a compact wall-mounted model would be the best option.

Heating scheme

The most common heating scheme for a private house with a gas boiler is water, in which, in addition to water, a special non-freezing liquid can serve as a coolant. Such a coolant is especially appropriate for houses in which people do not live permanently, but come for a while, for example, for a summer residence. Based on the method of fluid movement through heating pipes, modern systems can be divided into three types:

gravitational;
forced;
combined.

In the first case, the heating device provides for the natural circulation of water in the pipes due to the difference in height. This can be done by placing the boiler at the lowest point in the house. Heating water will rise up through the pipes, and when cooled, roll back to the boiler. This requires the use of larger diameter pipes and an increased amount of coolant in them. The disadvantage of the system is uneven heating; at the end of the line, the batteries warm up much worse than at the beginning.

In a forced heating system, liquid moves through pipes under the action of a circulation pump. In this case, the heating of the coolant and heating devices is uniform. There is only one drawback - dependence on the supply of electricity.

For non-stop operation of the circulation pump, you can use uninterruptible power supplies with powerful batteries, like those used for computer equipment.

Combined systems are a gravity version with a built-in pump. Here, even in the event of a power outage, the liquid will move due to the natural slope of the pipeline. The wiring from a gas boiler around the house can be single-pipe, two-pipe or radial. The first option is the most economical and simplest in terms of installation. In this case, the heating radiators are connected in series with one pipe. A single-pipe system can only be used in small houses; the difference in temperature at the inlet and outlet is very large. A two-pipe system is built from two circuits: supply and return. In this option, each radiator includes two pipes: one at a time, water is supplied from the boiler, and it flows through the “return” to its lower circuit. By installing taps near the heating radiators, you can adjust their heating according to your own wishes.

The radial distribution is mounted using a collector, from which each battery has its own pipe. The option is the most expensive, requiring a large number of pipes, but very effective in terms of uniform heating of rooms.

Calculation of gas consumption for heating a house

In order to accurately calculate the need for heat, complex engineering calculations will be required, taking into account not only the area or volume of the room, but also the heat capacity of wall finishing materials, the average temperature in the region by month of the year and other factors. For simplicity, we will use the simple assumption that heating a 10 m² room requires spending one kilowatt of energy per hour. Taking into account the fact that the boiler does not work all the time, but turns off as it heats up to a certain temperature, you can divide the resulting value in half. So, for a house of 100 m² you need to consume 100 * 24/2 = 120 kW per day, 150 m² - 180, 200 m² - 240. The heating season in the middle zone lasts approximately 7 months: from October to April, so the annual energy requirement will accordingly be:

100m² – 25200 kW;
150m² – 37800 kW;
200m² – 50400 kW.

To provide such an amount of energy, it is necessary to burn a certain volume of gas depending on its calorific value, that is, the amount of energy released during its combustion. For natural gas, mainly consisting of methane, this figure is 9.3 kW/m³. Liquefied water, which contains propane, ethylene and some other hydrocarbons, has a higher calorific value - 6.55 kW/l.

By dividing the amount of energy by the calorific value of the fuel, we obtain the total gas consumption depending on the area of the premises:

100 m² – 2709 cubic meters of natural gas or 3847 liters of liquefied gas;
150m² – 4064 cu.m. m. or 5771 l;
200m² – 5419 cubic meters m. or 7695 l.

Installation of gas heating

Gas heating in a private house is carried out in stages.

First of all, you should contact the regional gas service to agree on a solution and draw up a gas supply project. Further actions proceed according to the following scheme:

A calculation of the necessary materials and equipment is made.
The necessary components are purchased.
The heating system is being installed. These works can be done with your own hands, unlike “gas” installations.
A gas holder or storage tank from cylinders is installed if a liquefied gas supply scheme is selected.
An insertion is made into the main gas pipeline or storage tank and the pipe is inserted into the room.
Gas pipes are being installed inside the house.
Gas equipment is installed and connected to the heating system.
The coolant is being filled.
The functioning of the system is checked in different modes.

It is best to entrust the installation of the gas pipeline and devices to a team from the operating gas service. In this case, there will be fewer maintenance problems later.

The use of gas for heating is the best option for creating comfort and coziness in the premises of a private home. This solution is especially effective if there is a main gas pipeline in the village. At the same time, you must always remember that gas is a source of increased danger and it is unacceptable to neglect the recommendations of gas and fire services. If the installation of other systems in the house can be carried out independently, then it is better to entrust gas installation and all work associated with it to a professional with appropriate training and permits.

The concept of “autonomy” implies independence. If we talk about heating, then there is still a dependence – fuel. Today, the most popular “refueling” is gas. Therefore, to create such a system, you will need a gas boiler, which will be located in the house or an extension to it. Autonomous heating should be considered at the stage of purchasing or building a home. This is something worth talking about.

Equipment for arrangement

The creation of any heating system requires financial investment. But a lot depends not only on the quadrature, but also on the gas itself. When it is possible to connect to the central highway, then problems with “refueling” do not arise. But what to do when there is no such option?

The main task is to think through the delivery and storage of gas. Today it has become very popular to install gas tanks on your property. They are large metal containers into which gas is pumped using special equipment. Such a “barrel” is dug into the site so that it is below the freezing point of the soil. But in some cases they can make an exception and install a container on the surface (if the region has mild winters or the gas tank is protected from frost). As for volumes, it all depends on fuel consumption.

It’s worth saying right away that a gas tank is not cheap, and it’s extremely difficult to install it yourself. In order to somewhat reduce the costs of setting up such an autonomous system, you can agree with the owners of nearby plots to jointly purchase it. By calculating individual gas consumption, you can select the optimal volume of the gas tank. Then the specific installation point is simply determined.

Also, the autonomous gas system will contain other mandatory elements:

Gas heat generator. The power of the boiler depends on the size of the house it has to heat. There are two main types of installation - on the floor or on the wall. This does not affect the functionality of the equipment in any way. Floor-standing models are chosen by those who cannot, for some reason, mount the boiler on the wall, for example, if it is framed with plasterboard.
System of pipes and batteries. These elements touch almost every room in the house. Here it is worth paying attention not only to the price, but also to the performance characteristics. To do this, you will first need to decide on the boiler, because each model has its own heating range. Today, the most optimal material for pipes is metal-plastic. Well, as for radiators, everyone chooses them themselves, focusing on aesthetic preferences.

Shut-off valves. It is mounted in the circuit to enhance the saving effect. It is designed to control the supply of coolant and open the circuit. The main elements are shut-off and ball valves for radiators, needle valves and gate valves. Although these elements are small in size, the reliability of the entire system depends on their quality.
Operation control and regulation systems. Such elements allow you to achieve even greater savings in heating. Automation provides control over gas consumption, focusing on the temperature in the rooms. The pressure control system in the boiler also helps to optimize operation. Modern equipment, in most cases, already has these systems built-in. But if you wish, you can purchase a simpler model and gradually improve it.

It is important not only to want to make the house warm, but also to make miscalculations from the standpoint of economic feasibility. This will require a project plan. It indicates all the required components of the system, down to the name of the equipment and its power. If you wish, you can do this work yourself. But if there is no basic understanding, then it is better to entrust all the work to professionals.

Autonomous heating options

Electric and air heating systems are popular abroad. Water or antifreeze is used as a coolant. The main problem is choosing a heat source. The most popular boiler options are gas, electric and diesel. But there are also combined devices.

For private homes, it is important to choose a heating system that not only fits within a certain financial framework, but also pays off as quickly as possible. There are three main options:

Radiator heating. In this case, batteries and gas convectors are used, through which the heated coolant will flow. Heating radiators are devices of the convective-radiative principle. Their design contains round or elliptical sections, which are located separately from each other. Can be made of cast iron, steel, aluminum or bimetal. If we talk about convectors, then these devices operate on the principle of convection. But radiator heating moves the air in the room, which causes all the dust to rise.

Warm floor. A pipe system is installed in the floor through which the coolant will circulate. With this option, the room is heated evenly. But here it will be necessary to carry out major work - leveling the rough base, calculating the length of the coil, pouring a concrete screed, laying the final covering. Here the coolant will have a lower temperature than in the previous version, which causes fuel consumption to decrease.
And the installation cost is 15-20% lower than that of radiator heating.

Air heating. Here air acts as a coolant. This approach is relevant for rooms where there is high humidity, for example, a swimming pool or garage. In this case, financial investments will be minimal. But the air mobility is the highest here, and the largest heat losses are also observed.

For maximum effect, it is better to try to combine all of the above options into one system. Just choose your own heating type for each room.

Turnkey services

When there is no desire or knowledge to do all the work with your own hands, then there is always the opportunity to turn to professionals. Competent and trained people will not only provide a finished project or carry out the entire installation, but will also offer to purchase all the elements immediately from the company. Of course, all this will cost money.

The price of autonomous heating depends on the following factors:

the size and number of floors of the housing with which to work;
what is the total power of all additional elements (swimming pool, bathhouse, sauna, etc.), if any;
whether additional work will be required, for example, increasing the length of the gas pipeline or digging pits;
does the client want to create any other protection systems in addition to the standard set;

if the client has specific wishes for equipment companies.

All these points will affect the final figure of the project. But usually firms already have standard development plans.

On average, services look like this:

Creation of autonomous heating with a gas holder

Today, many people prefer complete independence. For this purpose, they install a special gas tank on their site - a gas holder. Depending on the volume, such a refill may last for at least 2-3 years. From a financial investment point of view, this is a very good option. But how much will the arrangement cost?

Projects with gas tanks are an order of magnitude more expensive than installing a simple gas heating system. Although you can compare prices from different representatives, the difference here will not be significant. But they create complete autonomy from any gas mains. True, such equipment must be serviced every year, and from the company that installed the equipment.

For a private home or country cottage, with the onset of cold weather, the problem of heating becomes urgent. Thanks to technological progress, today it is possible to create an autonomous heating system in your home using heating boilers and other related equipment. Coal, wood, and electricity can be used as fuel, but natural gas is still the most accessible and cheapest. This aspect is the main reason that today many citizens are trying to use gas to heat their homes. Properly designed autonomous gas heating of a private home will allow you not only to save your own money, but also to calmly await the onset of cold weather.

Despite the fact that today not all regions of our country are covered by a network of main gas pipelines for household gas, there are other, no less convenient ways to heat residential buildings with gas.

Autonomous gas heating - the main essence and principle of operation

conclusions

Gas is the most accessible and cheapest type of fuel. By installing a gas double-circuit boiler of the appropriate model in your home, you get interior heating and hot water supply.

If you have a problem with centralized gas supply, there is a way out. Install a gas storage facility on your site - a gas holder.

One refill of a liquefied gas tank is enough for 6-7 months of the heating season. In this situation, your heating system is almost completely independent; there is real profitability and efficiency of autonomous gas heating.
