Installation of heating gas equipment. Heating a house with gas cylinders: personal experience
Prices for gas heating of a private house on a turnkey basis
When choosing one or another heating scheme for a country house, the property owner strives to ensure maximum living comfort, but with minimal costs. For many reasons, it is rightfully considered ideal for private homes. gas heating, which is characterized by the greatest practicality and efficiency.
In order to achieve the optimal combination of gas heating efficiency and its costs, it is important to take into account all factors, from the costs associated with the design and installation of the heating system, to the calculation of upcoming operating costs, including the cost of purchasing energy resources. It is also necessary to choose the right equipment, as well as evaluate your own wishes for such a method of improving the comfort of your stay. We will try to analyze all this more clearly in this article.
Types of gas fuel
The design features of the gas heating system of a private house are largely determined by the types of fuel used.
The most common for many reasons is natural gas. Almost all property owners give preference to it, but not everyone has access to such an energy resource. And although most of our country is considered gasified, there are settlements so remote from the main highways that connecting to them will require incredible financial and resource costs. Therefore, along with the supply of natural gas, today there are other types of supplies of such energy resources.
As an alternative to connecting to the central gas main, a propane-butane mixture is used, which is otherwise called liquefied gas. It can be supplied in cylinders if its consumption is small, for example, for country houses, or it can be delivered in tanks for subsequent refilling of gas tanks - special tanks installed on a private plot. These containers are placed underground to protect their contents from exposure to solar energy or freezing temperatures. Considering the cost of preparing such a mixture and transportation costs, the price for this type of fuel is obviously several times higher than for natural gas. Therefore, such a system is less preferable, but it is widely and universally used as a way out in difficult situations.
Advantages of gas heating:
- efficiency. Gas is produced on the territory of our country, and is not imported from abroad, and therefore is considered one of the cheapest types of fuel. If we compare it with diesel, the discrepancy in favor of natural gas is ten points, and coal is 3 times more expensive. In addition, the gas does not leave combustion residues in such volumes that the burner can be cleaned with high regularity.
- comfort. Due to the almost complete combustion of fuel in gas boilers, the degree of wear is significantly reduced, due to which they are characterized by excellent durability. And the design itself is simple enough to master the functionality without any special knowledge. The almost silent operation of such heating equipment is also considered convenient, which reduces additional costs for the appropriate arrangement of the boiler room.
- automation. Gas is more controllable than other types of energy resources, so automation on such equipment is today an example of human genius. There are already models whose operation does not require the participation of the owner at all.
- environmental friendliness. Incineration waste is so insignificant that the risk of causing damage to nature during its disposal is minimal.
- high explosion hazard. Both natural and liquefied gas are considered explosive. But subject to a gross violation of current rules and regulations both in the process of creating such heating and when using it. Strict adherence to the recommendations of the manufacturers of this equipment, as well as the requirements of SNiP, is guaranteed to protect the house and its residents. However, in order to implement all the regulations, which are strictly controlled by special supervisory authorities, you will have to incur some material costs.
- terms of Use. For the normal functioning of gas equipment, a number of requirements must be met. The pressure in the gas pipeline must correspond to the established parameters. It is also necessary to ensure that there is no dirt in the boiler room. This is not always possible to achieve, so it is better to get help from an experienced specialist who will assess the specific operating conditions and give advice on selecting the most adapted equipment.
If the advantages of gas heating relate to the period of operation, then the owner of a country house will have to face the disadvantages at the stage of arranging this system.
Automation of gas equipment performs several functions - from maintaining temperature, according to individual comfort requirements, to adjusting energy consumption parameters. The latter has become possible today after the use of special “outboard” temperature sensors in the circuits, in accordance with the readings of which the burner operating mode is set. Therefore, such “smart” equipment is able to independently determine in what volumes energy resources should be consumed depending on the time of day or weather conditions. On average, savings from such implementation reach 30%.
Gas boilers are perfectly synchronized with each other, thanks to which they can be used to assemble a perfectly functioning boiler room, the power of which will be unlimited. As practice shows, two boilers of smaller power, but totally equivalent to one powerful one, will better cope with the task with higher efficiency. A classic of a modern heating system is the synchronization of two medium-power boilers used simultaneously in winter, and in summer - one of them for heating hot water.
Wall-mounted gas boilers.
Wall-mounted gas boilers are considered optimal for private homes due to the fact that they take up minimal space.

Gas heating in a country private house
Electric heating boilers are not installed in country houses
The affordable cost of liquefied gas has led to an increase in the popularity of its use as the main type of fuel for heating private country houses. In most cases, a gas heating system in a private house is organized by connecting natural gas. But even if there is no access to the main gas pipeline, you can always install equipment that runs on liquefied bottled fuel.
Benefits of using gas
Installing fuel boilers using natural or liquefied gas has a number of advantages compared to organizing a heating system based on liquid and solid fuel boiler units.
Among the most important, the following factors should be noted:
- Affordable cost of equipment, its installation, and the fuel itself.
- High reliability and durability of heating systems running on blue fuel.
- The small dimensions of the equipment make it possible to install it in almost any room.
- Double-circuit boilers allow you to provide a country house not only with heat, but also with hot water.
- Compared to other types of heating systems, those that run on gas are the most environmentally friendly, since gas causes the least damage to the environment when burned.
- Depending on the type of gas heating equipment selected, it can be installed both in the house and in a specially designated room, that is, in the boiler room.
Gas equipment calculation parameters
In order for gas equipment for heating a private home to fully meet its objectives, its selection is made on the basis of calculation. In this case, different parameters are taken into account, so it is better to entrust the calculation to specialists.
The main parameters are:
- Boiler power or total power of all boilers in the installation.
- Power of pumping equipment required for the installation of gas heating systems with forced movement of coolant.
- Technical parameters of heating radiators that heat rooms in the house.
- Possibility of installing additional heating systems, for example, heated floors.
- Availability and number of hot water consumers (sinks, baths, Jacuzzis, swimming pools, etc.).
Equipment selection
Heating is a comprehensive solution to many issues
The operating principle of gas boilers is based on heating the coolant by burning fuel. In order for engineering systems to operate uninterruptedly, it is necessary to select the right equipment for gas heating of a private home.
Such equipment must meet a number of requirements:
- Economical operation.
- Safety and reliability.
- Ease of use.
- Minimal maintenance.
- Suitable design (floor/wall).
- Aesthetic appearance.
It is also worth considering the presence or absence of a special room where a boiler room can be equipped. There are models on the market that can be installed directly in residential buildings, but most high-power units will require boiler room equipment.
Wall-mounted models are ideal for installation in areas such as the kitchen. Such units have an open or closed combustion chamber. If you have a chimney in your house, you can purchase a boiler in which the combustion chamber is open. If a chimney is not provided, only boilers with a closed chamber and a coaxial chimney can be installed.
Power, as noted above, is calculated based on the dimensions of the room. This can be done using a simple formula - the total area is multiplied by the height of the ceilings and the resulting result is divided by 25. The final figure will be the coefficient that is suitable for a private home. It is better to opt for a model with a little more power than the calculated one.
The last thing I would like to note when talking about choosing a boiler is the ability to switch between different types of fuel. Universal boiler equipment is presented on the market by almost all manufacturers. Most models have the ability to use two types of fuel. And the choice of option depends on which fuel is more available in a particular area.
Installation of a boiler room for a private house
When installing a heating system in a private home, the boiler room remains the most important component. The uninterrupted operation of the entire system, its safety and heating costs will depend on how correctly it is installed.
Requirements for these premises:
- they are required to be equipped with a chimney, which must have a height of the outer pipe of at least 50 cm above the level of the roof ridge;
- the room must have ventilation openings in the form of windows in the window opening and in the chimney;
- the room must have a separate exit to the street and a doorway width of at least 80 cm;
- Gas equipment should be installed at a distance of at least 30-40 cm from the wall.
In addition, for the installation of gas devices, you will need to draw up a project with the gas and technical supervision authorities and conclude a maintenance agreement. Without these pieces of paper, no master will agree to install gas devices, and the owner may receive high fines.
Automation for boilers
The main elements of the boiler room are:
- A boiler that heats the coolant.
- Boiler automation.
- Recharge system.
- Boiler (when installing a hot water supply system).
- Security group.
- Collecting and mixing equipment (collectors, pumps and other devices that distribute coolant along circuits).
- Expansion tanks.
- Chimney.
- Boiler piping.
- Boiler room wiring.
The most important equipment for the boiler room layout is the boiler. Its power directly determines not only the functioning, but also the configuration of the heating system.
Important! When choosing a unit, you need to take into account not only the calculated indicators, but also the total power of the remaining elements of the system and its additional components.
There are several main types of boilers, and each has its own technical, design and operational features. Boilers are:
- Wall-mounted.
- Floor-standing.
- Single-circuit.
- Dual-circuit.
- With open camera.
- With a closed camera.
- Condensation.
Wall options
They are wall mounted and suitable for small houses and cottages. They do not require the installation of a special boiler room, since their package already includes all the necessary additional equipment, automation, security group, etc.
Their important advantage is the affordable cost - both of the equipment itself and of the system piping.
The main disadvantage is a shorter service life.
Floor models
They are ideal for installation in a boiler room. The heat exchanger of such units can be made of either steel or cast iron.
Cast iron equipment has a longer service life. But there is a risk of microcracks forming in the body of cast iron due to careless transportation or installation. As a result, equipment quickly breaks down.
However, cast iron heat exchangers have a unique function of replacing a part that has failed, which distinguishes them from steel devices.
Single-circuit and double-circuit devices
Schematic division of boilers
The first ones have only a heating circuit in their design. If it is necessary to install a hot water system based on it, it is necessary to organize indirect heating of water from the boiler.
Single-circuit devices have special outputs for connection to the boiler. This solution allows the system to easily cope with even peak hot water consumption, ensuring complete uninterrupted water supply.
Double-circuit devices, as their name implies, have two circuits inside the housing - heating and hot water supply, which makes it possible to power two engineering systems from one unit.
Water for domestic hot water will be heated directly in the boiler through a second heat exchanger. According to the principle of operation, the heat exchanger resembles a conventional instantaneous water heater. Despite all the advantages of dual-circuit units, we must not forget that the priority is the DHW circuit. As a result, during water heating, the heating circuit is turned off, which leads to a gradual cooling of the radiators.
Such equipment is more suitable for small houses with a minimum number of hot water consumers or for houses with periodic residence.
Installing dual-circuit devices allows you to reduce the cost of installing a boiler room. All necessary additional equipment is integrated into the unit body. In fact, when installing a boiler room based on double-circuit models, it is enough to install only the boiler without additional equipment, which allows you to significantly minimize the cost of piping the boiler room.
Boilers with closed and open combustion chamber
Range of modern heating equipment
Units in which the combustion chamber is closed, or so-called coaxial, do not require a chimney. Their design uses a forced-air burner, as a result of which combustion products are forced out, and air is also taken from the outside.
The main disadvantage of models with a closed chamber is the noise that the fan built into the forced-air burner makes during operation. Therefore, these models are more suitable for arranging a separate boiler room than for installation in a residential area.
Boilers with an open combustion chamber are equipped with an atmospheric burner. In this case, the products formed during the combustion of gas or other fuel are discharged to the street through a regular chimney.
Such devices have a simple design and do not require complex maintenance. Their drawback is the need for a full-fledged chimney, which is best incorporated into the architecture of the building at the design stage. If the chimney was not provided, it will have to be installed, which will lead to a significant increase in the cost of installing a boiler room.
Condensing boilers
Such units appeared on the market relatively recently. During operation, they use not only the energy generated as a result of fuel combustion, but also the energy of condensation of steam from flue gases.
Note! The most important advantage of condensing-type devices is their high efficiency and, as a result, energy efficiency of use.
Another important advantage is the absence of the need to install a full-fledged chimney. The exhaust gas combustion products are removed using plastic smoke exhaust systems.

The boiler room is piped with polypropylene, copper or steel pipes. Polypropylene strapping is low cost and easy to install. When choosing this method, it should be taken into account that the material may deform over time. Despite this, polypropylene pipes are most often used for piping boiler rooms in private homes.
Copper piping is not only durable, but also aesthetically pleasing. However, it is used extremely rarely due to its high cost. Steel pipe was traditionally used for piping, but today it has been almost completely replaced from the market by modern materials.
When installing boiler equipment of very high power, only steel piping is possible, since this material can easily withstand even very high loads.
Heating system design
Installation of a heating system is one of the most difficult engineering tasks when building a private house. Experts do not recommend installing such systems yourself.
All installation work is carried out on the basis of a project developed only by qualified specialists. The project includes the calculation of power and the installation of all necessary equipment, as well as wiring diagrams for heating mains, the location of heating devices and additional system elements.

The actual installation work is carried out in several stages:
- Laying communications (on the ceiling, in the floor, in the walls).
- Boiler room installation (direct installation of the boiler).
- Installation of heated floors if necessary.
- Installation of radiators.
- Checking the installed system and putting it into operation.
Note! Work on the installation of gas equipment must be carried out by persons who have permission and a license to carry out this work.
Conclusion
Despite the complexity of installing autonomous heating systems in individual country houses, they are becoming increasingly popular. The most appropriate is the installation of such systems based on gas boiler equipment. Manufacturers present a variety of models that allow them to meet the urgent needs of any homeowner.
Heating in a private house with gas boilers - what a homeowner needs to know
Heating in a private house can be carried out from various energy sources - solid, liquid fuel or electricity. But the most popular and inexpensive are gas heating boilers of different functionality and location.
Gas heating of a country house
Among benefits can be distinguished
- ease of operation;
- high efficiency of gas boilers, which means high efficiency of the system as a whole;
- almost complete automation;
- rapid heating of rooms of any size;
- high efficiency associated with low fuel costs and low operating costs.
- environmental cleanliness and safety, since the percentage of harmful substances in emissions is very small.
High requirements for safety and reliability apply to gas heating at home, since heating is carried out through the use of flammable combustible substances using sophisticated equipment. Therefore, in order to avoid accidents, all design, installation and commissioning work must be carried out by highly qualified specialists with experience. Also, during the operation of a gas heating system, it is necessary to periodically monitor and prevent gas burners, taps and automation. In order to avoid emergency situations, such work must also be entrusted to specialists from service centers.
Among the disadvantages can be noted
- the need for mandatory compliance with fire safety rules when using gas equipment;
- mandatory availability of design documentation certified by the relevant authorities before starting installation of a gas heating system;
- It is necessary to have a pipeline for fuel supply and a chimney;
- the need for periodic preventive maintenance.
But, despite the above disadvantages, gas heating, due to the low price of fuel, continues to remain the most popular option for heating country houses.
Types of gas equipment for summer cottages and cottages
Gas boilers are usually divided into floor-mounted and wall-mounted.
Boilers There are steel and cast iron. They are no different in power, but steel ones are several times lighter, although the service life of cast iron ones significantly exceeds the service life of steel ones, so when installing a gas system, it is better to choose a cast iron boiler.
The correct design, installation and operation of the heating system has no less influence than the heat exchanger material on the service life of the boiler.
Wall-mounted boilers can be called a “boiler room in miniature”, because in a small case there is not only a burner, a heat exchanger and a control device, but also one or two circulation pumps, an expansion tank, a pressure gauge, a thermometer, a system that ensures the safe operation of the boiler and many other elements, without which the operation of a normal boiler house is indispensable.
I would like to draw your attention to the fact that according to the method of removing exhaust gases, boilers are divided into models with natural and forced draft. In forced draft boilers, exhaust gases are removed using a fan built into the boiler. Such models are ideal for rooms without a traditional chimney, since combustion products in this case are discharged through a special coaxial chimney, for which it is enough to make only a hole in the wall.

Boilers are made of steel and cast iron. They are no different in power, but steel ones are several times lighter, although the service life of cast iron ones significantly exceeds the service life of steel ones, so when installing a gas system, it is better to choose a cast iron boiler.
The advantage of this type of equipment is that you may not need repairs in the future.

Gas heating of a private house: main gas and bottled gas, choice of equipment
To solve the issue of gas heating in a private home, you need to decide on the source of gas supply: connecting to a gas main or using liquefied bottled gas. The second task is to make a choice of gas equipment: install a gas boiler, convector, or both. Now we will analyze all the components of this task in detail.
Connection to the gas main
It is possible to connect to an existing pipeline if a gas pipeline is nearby. To do this, turn to specialists. Gas is a deservedly popular fuel, environmentally friendly, but if handled incorrectly it can be dangerous. Therefore, they turn to gas workers and create a house gasification project, where the layout of gas pipes and the installation location of gas appliances are drawn on the house plan. The situational plan shows the location of the tie-in into the existing gas pipeline and the supply of gas pipes to the house. The specification indicates all materials and in what quantities they are needed to complete the gasification specified in the project. The explanatory note describes the necessary safety actions.
The underground part of the gas pipeline is made of polyethylene pipes. Overhead gas pipeline made of electric-welded steel pipes.
If there is a gas distribution substation, it receives main gas and reduces the pressure in the pipes that lead gas to residential buildings. Now they often use another method of lowering the pressure of gas flowing into homes. Gas distribution substations are not being built, which reduces the cost of gasification, for example, of villages. The main gas flows through the streets at medium pressure, and when the gas pipeline enters the territory of a household, a reducer is installed that reduces the pressure in the pipe to low pressure.
For the owner of a house that is being gasified, it matters which heating device he chooses. Read separately about heating systems in a private home.
a) Heating device: boiler
If the household will be heated using a gas boiler, then it is necessary to install steam heating in the house. The design must provide for a sufficient slope of the heating pipes so that the system is gravity-flowing and warms up well; the movement of water in the system can be forced by installing a pump.
The boiler power is determined by the heated area and heat losses of the household, and a thermal engineering calculation is performed. You can calculate the required boiler power based on the volume of water in the system.
Floor standing boiler installed in a small room - a furnace room. The combustion products are removed through the chimney. The combustion room is provided with natural and supply and exhaust ventilation. A window is made in the room. The door to the furnace room is cut by 3 cm; the door should open outward. An exhaust hood is installed for supply and exhaust ventilation.
Safety precautions provide for a gas alarm in the room where the boiler is installed at a height of 0.5 m from the ceiling and at a distance of one meter from the heating device. Read more about the room requirements for installing a gas boiler here.
Wall boiler in many ways more convenient and comfortable than floor-mounted. Installed on the wall, does not require much space. Supplied with a pump.
Single-circuit ones provide space heating, double-circuit ones also solve the issue of hot water supply. A wall-mounted boiler is called a “furnace in a box.” For such boilers there is no need to build chimneys or break through the ceiling of the house. Combustion products are forced out through a special pipe in the wall.
The wall-mounted boiler has an electrical connection. This point contains possible disadvantages in operating the boiler. If the light turns off, the boiler will not work. Good quality of supplied electricity is required.
b) Heating device: convector
A gas convector is a device that resembles a fireplace or a free-standing radiator or heater. Modern convectors have a decorative, neat appearance. There is a large selection on the market from different manufacturers.
In a room with a convector, an exhaust hood must be installed. This is due to the property of gas, when there is a leak, to rise upward and create an accumulation, for example, under the ceiling. When sparked, the gas can explode; it is not for nothing that it is called “explosive”. Leakage is unlikely and is only possible from pipe joints if some processes have occurred there over time. Gas workers call this event reinsurance. The convector is considered a safe device.
Gas convector – has its pros and cons:
+ the convector has such a device that when heating oxygen in the room is not burned, air intake for combustion is done outside the living space,
+ combustion products are removed outside the living space, no additional measures are necessary,
+ the room temperature is easily regulated, the set mode is maintained,
− Having a convector in a room may cause some inconvenience,
− Through hoods installed in a room with a convector, fresh air enters the room, but also cold during the cool season, so users plug them with something.
The principle of heating with main gas: main gas from the point of connection through the gas pipeline leading to the household is supplied to the furnace room to the boiler, which heats the water in the heating system or the gas pipeline supplies gas to the convectors.
Use of liquefied bottled gas
Heating a home with bottled liquefied gas is one of the types of autonomous heating. Any boiler can be configured to operate on liquefied gas; the burners are replaced. When choosing a boiler, you should pay attention to the minimum pressure at which it can continue to operate. This will help the boiler to consume the gas from the cylinder as much as possible. Convectors can be used to operate on liquefied gas, this is one of their advantages.
If main gas is not available, you can heat with liquefied gas. For the device you will need: cylinders, combs and reducers, hoses.
Device principle
Cylinders are combined into a group - usually from three to ten.
In a house with an area of 120 square meters, with heat loss measures taken: fiberglass windows, no drafts, cracks sealed, the house is insulated, approximately 12 kg of gas will be consumed per day for heating, which means that 8-10 fifty-liter cylinders will be required per month.
A cylinder or group of cylinders is placed outside the living space, the gas from them is supplied through a small gas pipeline to the boiler room where the boiler is located or directly to the convectors.
A more modern method of heating with liquefied gas using special tanks - gas holders. Gas tanks are placed above the ground or underground. You will need: gas pressure regulators, relief valves and safety shut-off valves, shut-off valves, instrumentation, pipelines, gas tanks. A gas pipeline is installed from the gas tank to the boiler room (furnace) or to the convectors. The gas tank is located at a distance of at least ten meters from the house.
A house with an area of two hundred square meters, heated with liquefied gas from a gas tank with a capacity of five cubic meters using a boiler with a capacity of 20 kilowatts, uses one or two gas tanks of gas per year. The installation of this heating system is carried out only by specialists.
Advantages and disadvantages of heating with liquefied gas:
Gas is an environmentally friendly fuel. A private house heated with gas becomes more comfortable and cozy. For all possible cases of country life, you can find a convenient and suitable option for gasification of a household.
Gas heating of a private house: selection of equipment
Gas heating of a private house, main gas and bottled gas, heating with boilers and convectors, the principle of the device.
I think it would be redundant to talk about the importance of heating, especially if the temperature outside is sub-zero. For thousands of years, people have tried in every possible way to heat their homes. At first these were fires and fireplaces, but with the development of technological progress, the method of heating also developed. Today, the most popular type of heating can be called gas heating in a private home, so let's take a closer look at it.
The main advantages of gas heating
The main advantage of gas heating is its low cost. Thus, a kilowatt-hour of thermal energy obtained from burning gas is only 30 kopecks, which is two times cheaper than heating with wood. In general, gas heating in a private home is a system designed to heat a room using thermal energy obtained from burning gas. Such a system consists of a gas boiler equipped with all the necessary associated devices, a gas pipeline and a heated coolant supply system. In most cases, water acts as a coolant - this is the most reliable and at the same time the cheapest option.
Important! Under no circumstances should main gas be confused with liquefied gas! If you heat a private house with gas in cylinders, it will cost six to seven times more than, for example, the same.
And now directly about the benefits of heating. Almost all of them are related to the features of the boiler, let's look at them:
- Gas boilers have small dimensions when compared with other analogues, and this is very valuable, especially when free space is limited;
- Thermal energy obtained by burning gas costs significantly less than when operating other systems;
- When operating such boilers, practically no noise is made;
- Finally, gas boilers are very easy to use, they do not require regular cleaning, and it is enough to carry out scheduled work once a year.
Schematic diagrams
In general, there are only two such schemes:
- Gas boilers.
- Gas.
Let's talk about each of the options.
A gas boiler
A distinctive feature of gas boilers is that when fuel burns, a liquid is heated, which subsequently spreads through heating devices by natural or artificial circulation. Such heating devices can be radiators, registers, heated floors, etc.
There may be several options for boilers, and the choice of one model or another will entirely depend on what your needs are.
Single and double circuit
Single-circuit devices are intended exclusively for heating a private home. And no options. The volumes of coolant in it are constant, they do not change.
Unlike him, double-circuit boiler can combine its direct “responsibilities” with heating water for household needs. This could be, for example, a storage tank equipped with a separate burner. Of course, in this case the boiler becomes part of not only the heating system, but also the water supply system.
Artificial and natural circulation
Gas heating in a private house can be done using boilers with natural circulation, in which air from the house enters the burner, and combustion products enter general ventilation, and devices with artificial circulation. In the second option, the air required for gas combustion comes from the street, and combustion products, on the contrary, are discharged to the street through a separate pipeline.
What are the differences between both options? Actually, there are only two of them:
- A boiler with artificial ventilation can be installed directly in a residential area.
- A device with natural circulation needs a separate room, which has a wide door and window, and its area must be at least 4 square meters.
Important! Regardless of the type of boiler chosen, connecting and starting the heating system must be carried out exclusively by gas service workers!
Condensing and convection boiler
The difference between both options is as follows. In the case of convective devices, the coolant receives thermal energy only from the combustion of fuel - gas, while in condensing boilers combustion products also participate, the heat of which is also removed. For this purpose, additional exchangers - economizers - are used.
But what is the difference between them for us, ordinary consumers?
- Firstly, we note that there is a very widespread opinion regarding convective boilers - the formation of condensation in them is extremely dangerous, since in addition to water, it also contains acids. This is true and it means that nothing good will happen for a heat exchanger that is not designed for such operating conditions. There is only one way to combat dew loss - to achieve the highest possible temperature of the heat exchanger, which, in other words, means: the temperature of the coolant flowing through the return pipeline must be at least 60 degrees. Consequently, convectors and wall radiators should be used as heating equipment with this type of boiler. You cannot use convectors installed in the floor, as well as the heater itself, because this will lead to nothing but burns to your feet.
- Condensing units, on the other hand, literally require a low heat exchanger temperature. The standard heating scheme using boilers of this type is as follows: radiators are installed under the windows, and a heated floor system is installed.
Convector
A characteristic difference of a gas convector is that heat is not transferred through a coolant - the heat source transfers it directly into the air of a private home. A coaxial pipe is used to remove gas combustion products: gas escapes through its core, and clean air enters the room through its shell. Actually, this is how individual gas heating is often installed in a private house if there is no gas main nearby.
How does a gas convector differ from similar devices? Let's get a look.
- To install or start a gas convector you do not need to have special knowledge; you can do it all yourself.
- To install such devices, you do not need special wiring or a separate room. This is a significant advantage. In addition, such a convector will cost significantly less than a bimetallic radiator (which, moreover, requires wiring).
- If the rooms are isolated, then each of them will require a separate convector.
- At the same time, the air is distributed unevenly; it will be hot near the ceiling and cold below. Although, if you look at it, underfloor heating systems have no such disadvantages.
Operating principle of gas boilers
Be that as it may, gas boilers are the most popular when installing a heating system. This is correct, because, as we have already said, heating with gas cylinders is very unprofitable, and for the operation of convectors it is cylinders that are required. So, the principle of operation of boilers is almost the same as that of other devices intended for heating. The thermal energy released during gas combustion heats the coolant. The latter, in fact, is the source of heat, which, using a pipeline system, reaches the most remote areas of a private house. So, gas boilers consist of the following elements:
- A furnace in which gas is burned.
- Pipes required for connection to the system.
- A burner that burns gas.
- A pipeline that lifts flammable gases.
- , which removes fuel combustion products to the outside.
Next comes the movement of the coolant. For this, there is another pipeline to which the radiators are connected. This is another important heating detail that needs to be given due attention, because they can have a variety of shapes and be made from a variety of materials.
In addition, gas heating in a private house also consists of a number of devices necessary to regulate the process. These are, for example, expansion tanks for accumulating excess liquid, a circulation pump, a temperature controller, an air vent and various valves.
DIY installation and installation
The heating system is perhaps the most important element of the house. Therefore, when constructing it, it is necessary to pay great attention to each stage. Especially if all the work will be done by hand. And now - a step-by-step technology for creating such a heating system.
Stage 1. We are drawing up a system project, which will include drawings and a working design. It is extremely important here to calculate the required power of the gas boiler, all radiators and the circulation pump.
Stage 2. We calculate a preliminary estimate.

If you have the opportunity to connect to a gas supply system, then when choosing a heating method, it becomes obvious that gas heating is the best option. This option is the most efficient and comfortable, therefore it is very popular both for heating residential and industrial premises.
Types of gas heating
Depending on the equipment used, this heating method differs into the following types:
- . In this case, a water heating system is installed in the house, but a gas boiler is used to heat it. This equipment can be floor or wall mounted, single or double circuit, and also have an open or closed combustion chamber. Heat exchangers can be cast iron, they are usually used in floor-standing boilers, or steel, they are more often installed in wall-mounted models. If the combustion chamber is open, then the air to ensure the combustion process comes from the room, and when it is closed, then from the street.
- Convectors. In this case, convectors are used for heating, but there is no need to install heating radiators and pipes for supplying coolant. A gas convector is easy and quick to install, and in terms of heating costs, this option will be cheaper than similar electrical equipment.
- Infrared emitters. This is modern equipment, usually used for large rooms and operates on the principle of solar radiation. Now there are models with a power of 1.5 kW, so they can also be used for heating cottages.
Device Features
The design of the heating system will depend on the equipment used. If a gas boiler is installed, then in addition to it there must be:
- Heating radiators.
- A piping system is needed to supply coolant.
- A pump is necessary to improve fluid circulation.
- Expansion tank.
- Automation system to control the process.
- Safety devices.
- Devices that are necessary for the removal of combustion products.
If convectors or infrared emitters are used, then in this case there is no need to install a piping system and radiators, since the room is heated directly from the installed equipment.
Operating principle
Gas heating has a simple and understandable operating principle. When a gas boiler is used to heat a room, it is connected to a heating system consisting of radiators and a pipeline, which usually contains water, but may also contain antifreeze. Entering the heat exchanger located inside the boiler, the water is heated, after which it moves through the piping system to the radiators. The movement of water can occur by gravity, then pipes and radiators are installed with a certain slope or using a circulation pump. After the heated water releases heat into the room through the radiators, it returns to the boiler again and the whole process is repeated.
When convectors or infrared emitters are used, this equipment does not require additional installation of piping and radiators, since it independently heats the air in the room.
Areas of use
Gas heating can operate from the main gas pipeline or using liquefied gas. If there is a gas pipeline, then an apartment, house, or industrial premises can be heated in this way. In the absence of a centralized gas supply, equipment running on liquefied gas is used. It is usually used in private homes, shops, and cottages.
Infrared gas emitters are usually used to heat large areas, such as shopping centers, industrial buildings, sports or concert halls. Such equipment is installed under the ceiling, which is very convenient, since it does not take up free space. Now low-power infrared gas emitters have appeared that can be used to heat a private home.
How to choose gas heating
When choosing this type of heating, it is necessary to take into account whether people will be in this room constantly or periodically. If there is no need for gas heating to work constantly, then it is better to install convectors or infrared emitters. In this case, there is no coolant in the form of water, so it will not freeze when heating is not carried out.
If it is necessary for the room to be heated constantly, then it is best to use water heating, the water in which is heated using a gas boiler. This option not only allows you to constantly and evenly heat the room; when using a double-circuit boiler, you will also be provided with hot water, which can be used for various household needs.
If we talk about gas boilers, they can be wall-mounted or floor-mounted; the former are more compact. If the boiler is single-circuit, then a capacitive boiler can be installed, but it is easier and more convenient to obtain hot water using double-circuit equipment in which a flow-through heat exchanger is installed.
Floor-standing boilers are more expensive, they require more space, but the power of such equipment will be higher. Their installation usually requires a separate boiler room. In addition, when installing a floor-standing boiler, there must be a vertical smoke channel, which can be made inside or outside the building.
Floor-standing boilers usually have cast iron heat exchangers, so their service life is longer than that of wall-mounted models. Such equipment can be equipped with a furnace with a fan burner, which allows the use of not only gas, but also liquid fuel or pellets as fuel.
Advantages and disadvantages
Since gas heating is mainly carried out using a boiler, a system of pipes and radiators through which water moves, let’s consider the main advantages of this solution:
- High efficiency.
- Since the system is a closed cycle, the initial volume of coolant does not change.
- If you have certain skills, you can make water gas heating yourself.
- Uniform heating of all rooms.
The disadvantages of a water heating system, which is heated by gas, will be as follows:
- It is necessary to constantly maintain the cleanliness of heating radiators, since when they become dirty, the heating efficiency decreases sharply.
- After switching on, water heating warms up the room more slowly than air heating.
- Pipes and radiators are gradually damaged by corrosion and may fail.
- Water that acts as a coolant must have a minimum of salts, so it is best to use distilled water.
- In winter, it cannot be turned off, as the coolant may freeze, with the exception of the use of antifreeze.
If we talk about the use of convectors or infrared emitters, their advantage is that there are no pipes and radiators, they can be turned on and off in any weather, and heating a cold room occurs faster. The main disadvantage of such heating is that the temperature near the heating equipment will be higher than in other places in the room.
Operating rules
A gas boiler is the main element of a gas heating system and to ensure its safe and reliable operation, specialists must carry out preventive inspections at least once a year.
Only qualified personnel should install gas equipment, but before doing so, you must obtain all relevant permits.
When deciding to rebuild a room that uses gas heating for heating, it is necessary to agree on a new project. In case of uncoordinated construction work, gas equipment may not work correctly and this will lead to the formation of carbon monoxide.
Gas heating will be an effective and affordable way to heat both residential and industrial, commercial or other premises. It is easy to maintain and can operate both on natural gas, when there is a gas main nearby, and on liquefied gas, when it is not possible to connect to a centralized gas supply.
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).
Diagram of a double-circuit gas boiler
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.
