Heating a country house with a gas boiler. Types and features of gas equipment for home heating. Creation of autonomous heating with a gas holder

Spring is coming, but the question of how and with what to heat a country house does not lose its relevance.

Regular readers of our site have already managed to familiarize themselves with the article: “”.

Despite the fact that there are many heating systems on the market, many residents would like to heat their home with main gas.

However, it is not always possible to connect to a pipeline with “blue fuel”. If there is no gas and gasification of your individual housing is not possible in the near future, liquefied gas from cylinders will be an alternative.

Is gas heating profitable?

It seems that organizing autonomous gas heating of a private house is easy and simple. All you need is:

  • Buy a gas boiler. Most boilers operating on main gas can also operate on liquefied gas. To do this, you need to change the injectors and, if necessary, reconfigure the control system;
  • Purchase a reducer, gas equipment and shut-off valves;
  • Connect and configure the heating system.

The main questions that arise for any homeowner who is thinking about a liquefied gas heating system:

  • Will I be able to heat the house;
  • How long can a boiler operate on one cylinder?

Autonomous gas heating of a private house is best organized using liquefied gas cylinders with a capacity of 50 liters.

The practical experience of forum members suggests that heating a private house with gas from cylinders is unprofitable if the cottage is poorly insulated and the building has large heat losses. It is also necessary to take into account the total area of ​​the country house. Heating with gas from cylinders of a cottage with an area of ​​150-200 sq.m. can cost a pretty penny.

In this case, solid fuel boilers can be an alternative.

– I heard that one 50 liter container is enough for 1-2 days of operation (and this does not take into account the use of hot water).

– I heard that one cylinder with a capacity of 50 liters is enough for 1-2 days of work (and this does not take into account the use of hot water).

Schweik:

– I heated a house with an area of ​​70 sq.m. with gas. On average (depending on the outside temperature), one 50 liter cylinder was enough for me for a period of 1 to 7 days.

Endless:

– I have a frame house that is well insulated. I heat approximately 140 sq.m. At outside temperatures down to -20°C, three cylinders are enough for 5-6 days. At - 5°C – for 10 days.

– I have a house with an area of ​​145 sq.m., the foundation is USHP, underfloor heating plus hot water supply. The boiler was turned on twice a day, for 2-3 hours. 50 l cylinders are filled with 20 kg. The temperature in the house was set to 23°C. Costs per month are as follows:

  • November – 4 cylinders were used. Outside temperature +5-0°C.
  • December – 10 pieces left. The outside temperature is -10 -27°C.
  • January - 8 pieces left. The outside temperature is -5 - 20°C.
  • February – 7 pieces left. The outside temperature is -5 -15°C.
  • March – 6 pieces left. The outside temperature is -5 +5°C.

One gas cylinder holds from 35 to 42 liters of gas, in liquid form it is 22 kg. Liquefied gas consumption for any boiler is 15 liters per day per 100 sq.m. heated area.

Before you understand whether the game is worth the candle and whether autonomous gas heating of a country house will pay off, you need to familiarize yourself with the following data, which presents the economic feasibility of this or that type of heating.

1. = 33 kopecks/kWh.

2. An electric boiler operating in conjunction with a thermal accumulator (thermal accumulator) at a night tariff = 0.92-1.32 rubles/kWh.

3. Pellet boiler = 1.20 -1.32 rubles/kWh.

For comparison, the heating efficiency of liquefied gas is only 2.32 rubles/kWh.

When calculating the efficiency of a particular heating system, it is necessary to take into account that in the suburbs of Moscow and other regions there may be their own priorities in choosing fuel, which depend on its availability and climatic conditions. In some places it is cheaper to heat a house with coal, and in others with wood.

When calculating the profitability of heating with liquefied gas, many forget that the cylinders will have to be transported to a gas station on average once a week, and this is an additional expense - both monetary and time. Therefore, heating with liquefied gas can be profitable if 4 conditions are met:

  • Small house area - up to 100 sq.m.;
  • The house is well insulated;
  • In the near future, it is planned to gasify your village; main gas will be connected. In this case, heating with liquefied gas is a temporary measure that allows you not to buy two different boilers;
  • A liquefied gas boiler is a backup boiler and works in conjunction with other heating appliances.

Evo:

– When I leave for work, I turn off the home gas boiler and turn on the heaters that run on electricity, because... in frosts below -20°C the gas quickly runs out. In this “gentle” mode, two cylinders are enough for me for 7 days. And this includes the preparation of hot water. I recommend purchasing at least 3 cylinders. One for boiler operation, one as a reserve, one for refueling.

You can also mount a combination of an electric and gas boiler.

Despite the increase in the cost of such a heating system, the overpayment is not for the sake of savings, but to increase comfort.

In this case, the need to travel and refill containers is partially eliminated.

Features of gas cylinder heating

To install a reliable and safe liquefied gas heating system, it is necessary to understand its features, which are determined by the properties of this fuel.

The cylinders are filled with a mixture of propane and butane. This mixture, at high pressure, is in a liquid state, which is necessary for its transportation. The containers can also be filled with different types of fuel, depending on the season:

  • technical butane (BT);
  • summer technical mixture of propane and butane (SPBTL);
  • winter technical mixture of propane and butane (SPBTZ).

Liquefied hydrocarbon gases (propane-butane) are abbreviated as LPG.

Gas heating requires special attention in winter.

– We decided to heat a house with an area of ​​120 sq.m. using a gas boiler running on liquefied gas. Gas cylinders are kept outside in metal cabinets. There is one for the stove, and a bundle of 5 cylinders is made for the gas boiler, but so far only 2 are connected. When the temperature dropped to -2°C, a problem arose - gas does not flow, and the boiler, accordingly, does not work. I think the gas froze.

Gas does not freeze in pipes or cylinders. It simply does not evaporate, and again turns into liquid inside the gas pipe if it has a negative temperature.

This happens for the following reason. The boiling point of butane is about 0°C. The boiling point of propane is -40°C. At an outside temperature of -10°C, the propane-butane mixture in the cylinder boils, producing the gaseous fraction necessary for the operation of the boiler. The propane will evaporate first, and only then will it come to the butane. During this process, heat is absorbed. The balloon begins to freeze. As a result, the gas remaining in the cylinder (butane) also cools down. This leads to a decrease in the degree of its evaporation. Accordingly, the pressure required for boiler operation drops.

There is only one way out - to prevent the cylinder from freezing and warm it to the positive temperature necessary to evaporate the butane. You can do this as suggested by a forum member with the nickname Ruslan2.

– In my opinion, the best way to deal with this problem is to force the gas cylinders to be blown with warm air from the room (boiler room) where the boiler is installed: with a fan through aluminum corrugation or plastic air ducts inserted into gas boxes, etc.

You can also heat cylinders (but not with exposed electrical cables!) according to the principle of a warm water floor, placing them in an insulated gas cabinet.

Safety precautions when using gas equipment

The propane-butane mixture is much heavier than air. Liquefied gas from cylinders always accumulates at the bottom. If there is a gas leak, if the cylinder is in the room, you may simply not smell it until it reaches an explosive concentration. Therefore, it is planned to install the container outdoors, vertically in an iron box with holes at the bottom and top for ventilation.

gray-haired2:

“I know a case where a man lowered a gas cylinder into the cellar. One day the homeowner decided to pick some potatoes. He climbed into the cellar. He did not smell the gas, but... There was no switch there, so he simply screwed the light bulb into the socket. There was an explosion. The man was lucky; being at the epicenter of the explosion, he escaped with only a concussion, and his garage and two neighboring ones were left with a pile of construction debris.

Safety rules prohibit: placing gas cylinders in the underground, basements, cellars, holes dug in the yard or near the house.

  • It is prohibited to use electric heaters, heating cables, heating elements, etc. to heat gas cylinders.
  • Gas cylinders must be placed in special cabinets installed on the north side of the house.

  • The cylinder cannot be filled more than 80% of its volume. Liquid gas has a high coefficient of volumetric expansion. This means that with increasing temperature, the volume of gas in the vessel increases. The expansion coefficient of the propane-butane mixture is about 7%. According to Russian standards, 15% is left for expansion. A cylinder of any thickness and strength will burst if it is filled to more than 93% in a frost of -20°C and brought into a room where it is +20°C.

  • All detachable connections on the gas main must be checked for leaks by soaping.
  • Detachable connections are made at the points of connection of various elements where other connections are not possible (taps, meters, gas appliances, etc.)

  • Gas pipelines are made of steel pipes with a wall thickness of at least 2 mm. When passing through walls, the pipe is placed in a case foamed with soft material. The boiler can be connected to the gas pipeline using a flexible connection specially designed for this purpose. The connection of the reducer to the gas pipeline is made with a rubber-fabric sleeve (durite hose).

  • If the cylinder is located in a room next to the boiler, then the connection is made with a rubber-fabric sleeve.

When creating utility lines for a country house, the most important point for any owner is the correct choice of heating system for the building. Furnaces and boilers operating on solid and liquid fuels, gas and electricity are used as heat generators installed in homes. Today in Russia, gas heating of a country house is considered the most convenient and affordable, options for which will be discussed in this publication.

Classification of gas heating systems

Natural gas is an energy carrier that is supplied to the consumer:

  1. under pressure through a centralized line;
  2. in a liquefied state, by filling specialized containers - gas holders or cylinders.

In the first case, the gas flows through a central pipe directly into the distribution device, which equalizes the pressure between the household gas supply system and the main line. Only after this does natural gas enter the home directly to the heat generator. In the second option, the role of the distribution device is played by the gearbox. It is this device that equalizes the pressure between the container and the point of consumption.

Regardless of the type of system, the most popular among our compatriots is the following gas equipment for heating a private home: gas heating boiler, convector. Next, the design features, advantages and disadvantages of a centralized and autonomous heating system for a country house with natural gas will be considered.

Autonomous gas heating of a country house is used if there is no main gas pipeline running near the building or the gas pressure in it is too low for normal operation of the heating devices.

Equipment

To store liquefied gas, you need to install a gas tank. It is a tank that is installed underground. Through an underground gas pipeline, fuel is supplied from the reservoir to points of consumption.

If a temporary autonomous gas supply system is assumed, then a ground location of the tank is also allowed.

Installing a gas tank cannot be called a budget solution. That is why in Europe it is common to jointly install one underground tank for storing liquefied gas, which is used by several homeowners. In this case, the cost of installing the tank is reduced several times. For those who cannot afford to create a storage facility for “blue fuel” on their personal plot, the only option left is gas heating of a private house with cylinders filled with liquefied gas.

Operating a gas tank if its installation is not of sufficient quality is extremely dangerous and harmful: damage to the tank can cause a gas leak.

With an autonomous heating system, heating boilers with a specialized burner for liquefied gas, gas convectors and infrared reflectors are used as heat generators. The first, when burning fuel, heat the coolant, which, circulating through the system, gives off its heat to the air. Radiators are used to increase the heat exchange area.

Convectors are local heating devices. The operating principle of these installations is to heat the radiator, which releases heat to the air in the heated room. To control the operation of convectors, thermostats are used, on which the upper and lower values ​​are set for each heated zone.

Infrared reflectors are heating devices that reflect thermal radiation from heated ceramic plates. Therefore, infrared radiation heats interior items and, as a result, the room in which the device is installed.

Traditional heating scheme

Among Russians, the most popular is the traditional gas heating scheme in a private house, in which the boiler heats the coolant by burning blue fuel. Most often, ordinary water acts as a coolant, which moves through the system using a pump or natural draft. The operating principle of such a system is simple: the boiler heats water circulating through a heat exchanger. Next, the water flows through the pipeline to the radiators. In them, the coolant loses some of the heat, after which it returns to the boiler and is heated again. The use of a pump allows more complex heating systems, for example, a combination of underfloor heating with radiators. The figure below shows a standard diagram of a traditional autonomous heating system for a country house.

With natural coolant circulation, a simplified diagram of the heating system looks like this:

Regardless of the choice of one or another heating scheme for a country house, calculations and installation must be carried out by professionals.

Advantages and Disadvantages

The main advantage of autonomous gas heating is stable pressure in the gas pipeline, which cannot be said about main fuel. Heating a dacha with gas from cylinders allows year-round living in a country house, ensuring a high level of thermal comfort and full automation of the heating and hot water supply system.

Now, a few words about the shortcomings. Gas purchase costs. In economy mode, to heat a small two-story country house, you will need 6 to 10 cylinders of liquefied gas every month. And this, we repeat, is in the mode of maintaining the room temperature at 16°C from 23:00 to 5:00 daily; from 9:00 to 17:00 on weekdays. On weekends and in the evenings, the room temperature is maintained at around 22°C. The required amount of gas will be accurately calculated in the project documentation, based on the power of the heat generator and the volume of “blue fuel” consumption.

If you have to use cylinders for gas heating, then for their storage you need to allocate a separate room, created in accordance with all fire safety rules, or make a fireproof, better insulated cabinet.

Gas central heating

The presence of main gas in a country house allows its use with virtually no restrictions. The only obstacle for the homeowner and the inhabitants of the house may not be the volume of the container for storing blue fuel, but the size of the wallet.

As heat generators, as in the case of autonomous heating of a house, water heating boilers, a piping system, radiators and shut-off valves are used. The only difference between a boiler for liquefied gas and heaters working with natural blue fuel is the design of the burner. Most modern heating boilers are equipped with burners for burning both natural and liquefied gas.

Gas heating boilers differ:

  • By installation method. Today, the air conditioning equipment market offers a wide range of floor-mounted and wall-mounted boilers. Due to the fact that floor-mounted heat generators are not limited in weight, they are often equipped with a durable cast-iron heat exchanger. Wall-mounted installations, as a rule, have less power, but are equipped with highly efficient heat exchangers made of non-ferrous metals or stainless steel.
  • By functionality. Boiler units are single-circuit and double-circuit. In other words: the first serve only to heat the coolant that is used in the heating system of the house; the second type of device is used for heating and creating domestic hot water at home.
  • By type of traction. In boiler units with an open combustion chamber, exhaust gases are removed due to. The air required for fuel combustion is sucked in from the room. In heaters with a closed combustion chamber, forced draft is created through the use of an air turbine. All combustion products are removed, and fresh air is supplied through or a separate smoke removal system.

Today, convection and condensation gas heating boilers are very popular among Russian consumers, the efficiency of which, in contrast to the usual 75%, varies at around 95-99%.

Structure of a gas heating system

Any gas heating scheme that involves the use of a liquid coolant includes: a heat generator, its piping, one or more heating circuits. The boiler piping includes the necessary shut-off valves, blast valves and an expansion tank, pressure or non-pressure. If the system is circulation, then the boiler piping must also include a pump. The circuits themselves can be made using a one-pipe or two-pipe scheme.

A single-pipe configuration is when the coolant bypasses the radiators in the order from the installation. With this scheme, significant pipe savings occur, but it is almost impossible to achieve uniform heating of all rooms.

With a two-pipe system configuration, the heated coolant is simultaneously supplied to all radiators. When using such a scheme, it is possible to control and change the heating temperature in each room through the use of mechanical regulators on each radiator.

The figure shows a typical gas heating scheme for a two-story private house.

Advantages and disadvantages of heating a home with natural gas

The advantages of gas heating are obvious:

  • Availability. Main gas in Russia is the cheapest fuel, even in relation to pallets and other types of solid fuel.
  • The ability to create a high level of thermal comfort in the home.
  • Environmental friendliness. In modern low-temperature boiler units, emissions of fuel combustion products into the atmosphere are minimized.
  • Efficiency. The use of modern heating devices makes it possible to increase the efficiency of natural gas combustion to 99%.

Despite the many obvious advantages, gas heating also has disadvantages. Gasification of a country house is a procedure that requires not only enormous financial, but also time costs. And this is only the cost of connecting to the highway. Further, enormous investments will be required to calculate the necessary regulating device that equalizes the pressure between the main line and the household system; creation of competent piping that disfigures the facade of the house, and other types of work. The cost of a gasification project for a private home can amount to tens of thousands of rubles and an unlimited time frame.

Despite this, gas heating is the cheapest and most trouble-free system, which allows the owner to live comfortably in a country house and use “blue fuel” at any time of the year.

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 at minimal costs. For many reasons, it is rightfully considered ideal for private homes. gas heating, which is characterized by the greatest practicality and efficiency.

To achieve the optimal combination of gas heating efficiency and 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 penalties.

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.

Pay attention! 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.

Pay attention! 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 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.

The cottage's gas equipment is not represented by single models.

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 made. 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 possible only 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 holder 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.

Using gas heating in a private home is one of the most effective and economical options when choosing heating systems. However, in order for the system to work properly, many details must be provided before installation. In particular, it will be necessary to select equipment of suitable power, develop an effective piping that will ensure minimal heat loss, and decide which gas source will be used to operate the equipment.

Gas sources

Natural gas is a universal type of fuel, which can be obtained from a transportation pipeline (provided it is available nearby) or liquefied gas can be used from special storage tanks. The main advantage of gas is its high energy efficiency. At an affordable price, it has a high combustion temperature, allowing an efficiency of 95% of the power of boilers and boiler equipment.

Main pipeline

Gas heating when connected to the main pipeline is the cheapest and most energy-efficient option for a country house. If there is a gas main in the village or near your home, you need to arrange a connection to it and receive fuel in the required quantity. The use of main gas pipelines has the following advantages:

  • stable pressure in the network, no need to calibrate boiler equipment, or worry that if the pressure drops, the heating efficiency will decrease;
  • high quality fuel. The gas in the pipeline meets supply standards, has a high degree of purification and calorie content, ensuring effective heating;
  • affordable price compared to other energy sources, as well as liquefied gas.

The only drawback, perhaps, is the inability to control the pressure, turning on and off the main gas supply. If the gas supply in your area is unstable, you need to be prepared for this in advance.

Gas holder

Gas heating using a gas holder is an effective solution for facilities that do not have the ability to connect to main lines, but require a significant fuel resource to ensure the operation of several heating points, heating and water heating at once. The gas tank is a steel container designed for operation under high pressure conditions. The tank is equipped with shut-off valves and other devices for injection and subsequent release of gas into the domestic gas pipeline system.

The use of gas holders has the following advantages:

  • independent control of gas supply parameters, you can adjust the pressure and other characteristics in the gas system;
  • independence from failures in the main system, completely autonomous heating in the house;
  • quite a large supply of gas. Refilling is required once a month with reasonable consumption and choosing a container of suitable capacity.

The disadvantage of a gas holder is that it is actually a container with a flammable substance located on the territory of a suburban area. To eliminate any malfunctions and the likelihood of emergencies, it is necessary to strictly follow the rules for the installation and operation of gas tanks. The rules are developed by the equipment manufacturer and specified in the state standard for installation work. In addition, in order to install a gas tank and conduct gas from it, it is necessary to obtain permission from the authorities, for which the project will need to be approved by the city gas office.

Cylinders

Heating using liquefied gas cylinders is a rather labor-intensive process. Since gas cylinders have a small volume (up to 100 liters), they often have to be changed and refilled. This option for individual heating is used in cases where we are talking about seasonal housing, where the owners stay for several weeks throughout the winter. In such conditions, installing a gas tank is impractical due to the high price and complexity of the project. Gas supply using cylinders has the following advantages:

  • suitable for situations where heating is needed for several weeks throughout the winter;
  • allows you to save money by eliminating the need to operate complex gas equipment;
  • no project development or approval is required.

In the case of gas cylinders, the same problem occurs as with a gas holder. Operating containers with flammable substances can be dangerous if the rules are not followed. A separate room must be equipped for cylinders to prevent the possibility of overheating and accidental fire with subsequent detonation of other containers. If technological rules are followed, risks are reduced to a minimum level.

Choosing a gas boiler

Gas equipment includes boilers, without which heating a home is impossible. The choice of a gas heating boiler should be approached extremely carefully, taking into account the fact that there are many models on sale, designed for different operating conditions.

Boilers differ in the following parameters:

  • installation location (wall, floor);
  • number of circuits (single-circuit only for heating and double-circuit, combining the functions of heating and heating water for domestic needs);
  • type of traction (natural or forced);
  • burner option (atmospheric or supercharged);
  • type of combustion chamber (open or closed with afterburning of condensation gases, which increases the efficiency of the boiler).

Many boilers are equipped with an automation system that monitors the presence of fire when the gas is on and shuts off the supply when it dies out, as well as automation that regulates the temperature of the coolant. Modern gas boilers have electronic or analogue controls that allow you to regulate the heating temperature with high precision.

Pay attention! An important factor is the power of the boiler. It is calculated based on the fact that 1 kW of energy heats 10 m2 at a standard ceiling height.

These figures may fluctuate slightly depending on how well the room is insulated. When calculating, you need to take a gas boiler with a margin of 10-15% of the maximum required power. This will allow the equipment to operate without overload and extend its service life.

Thanks to its fairly simple design, you can install gas boiler equipment yourself. The challenge is to correctly connect the water circuits, gas supply and exhaust of the chimney system.

Installation Requirements

Any heating project requires approval from the city gas agency and a number of other services and authorities. Permission to install the boiler will only be given if the installation of the equipment is carried out taking into account the current regulations.

The basic rules for installing gas equipment are as follows:

  • a special room must be allocated for the installation of a gas boiler; it is prohibited to install boilers in corridors, kitchens and living rooms;
  • the installation room must have supply and exhaust ventilation, a window or a vent for air circulation;
  • the boiler is installed on a durable, non-flammable base made of concrete, stone, brick or other similar material;
  • the boiler must be equipped with a chimney to remove combustion products and prevent their accumulation in the room where the equipment is operated;
  • There should be no gas cylinders or other flammable or explosive items in the room with the boiler.

It is also necessary to coordinate design requirements when installing gas tanks. Gas tanks must be installed outdoors, at a certain distance from residential and technical facilities, at a depth that meets safety requirements.

If installation rules are violated, you may receive a fine from the inspection authorities, even to the extent that the equipment will be sealed until all deficiencies that could lead to an accident are corrected.

Other important equipment

Instead of gas boilers, convectors can be used for heating. They convert energy from gas combustion into infrared (thermal) radiation. Such gas equipment is suitable for additional heating, installation in a country house, garage or country house, subject to a temporary stay there. Many gas convectors are portable equipment. There is no need to obtain permits for their installation; you just need to adhere to basic safety rules.

Do not also forget that when connecting gas, additional equipment will be required, such as meters, pressure sensors, pumps, pipes for the chimney and for the water circuit. You will need radiators and, most likely, a gas stove for cooking.

Heating device diagram

In order for the heating to work efficiently and without failures, it is necessary to correctly wire the system. Wiring refers to all the equipment used and the methods for connecting it to the network.

The following heating device schemes differ:

  • gravity flow. Their advantage is their comparative cheapness, since they do not require pumping equipment; water circulates under the influence of gravity. However, such systems can only be used in small one-story buildings. If the system has a significant volume of coolant and has a complex circuit route, then this scheme will not be suitable;
  • forced. The coolant moves using a circulation pump. The advantage is that the rapid movement of the coolant allows the temperature to be uniformly transferred throughout the entire system, eliminating overheating or cooling of the pipes. The disadvantage is the need to purchase additional circulation pumping equipment.

To increase the efficiency of boilers and the heating system as a whole, storage tanks can be installed. The heat storage tank should be located in close proximity to the gas boiler and connected to the hot and cold circuit. Hot water is accumulated in the tank, which allows stabilizing the temperature difference at the inlet and outlet of the boiler, and also provides a small reserve of prepared coolant after the boiler is turned off.

There are many connection schemes using various useful components that increase the efficiency of heating. Before drawing up a project, it is recommended to consult with a specialist in this field.

Gas boiler as a heat source used everywhere and is considered the optimal means of heating a room.

Natural gas - the most accessible and inexpensive energy source. This is why gas heating is so popular.

Even if there is no possibility of connecting to the highway, you can consider alternative home gasification projects(gas holder, gas cylinders).

Gas heating system

The use of gas boilers for space heating is the most common method of heating private homes. When heating a house with gas no waste appears: no dust, no dirt.

There are floor-standing and wall-mounted boilers. They have the following characteristics:

  1. Floor-standing appliances have a significant mass due to the cast iron heat exchangers installed in them. They require a separate room. They work up to 50 years thanks to the anti-corrosion properties of cast iron.
  2. Wall gas boilers can be installed in the kitchen or in the corridors. The heat exchangers in them are made of steel, so they have less weight and a rather presentable appearance; the devices fit well into the home interior. Serve from 15 to 20 years, have a lower cost.

There are two types boilers: single-circuit, used exclusively for heating, and double-circuit, which also heats water.

Devices are classified and by type of combustion chamber. It happens:

  • open— consumes air from the room (accordingly, additional ventilation is required);
  • closed- takes in the street air.

Operating principle, diagram

The heating system using a gas boiler is standard. It contains:

  • heat source;
  • water as a coolant;
  • circulation pump;
  • pipeline;
  • expansion tank;
  • heating elements;
  • shut-off and control valves.

Photo 1. Heating diagram for a private house using a gas boiler. Radiators and heated floors are used for heating.

Available on the market many models gas boilers, but Fundamentally, they are practically no different from each other. Using internal sensors and thermostats, the controller supplies natural gas to the combustion chamber. In the heat exchanger, water is heated to the required temperature and pumped into the heating circuit. Heating will continue until the required temperature is reached.

In the future, automation will maintain the temperature at a given level, without requiring human control. Double-circuit boilers involve the use of water from a heat exchanger for domestic needs, but fluid intake to maintain balance is somewhat limited and depends on the size and power of the unit. Some gas boilers are used in underfloor heating systems and even for heating swimming pools and greenhouses.

Pros and cons

Gas boilers are the most economical heat sources, but they have other positive aspects:

  • Can heat large rooms.
  • They have a high efficiency ( 80—95% ).
  • Warms up rooms quickly.
  • There is no need to monitor the boiler, everything is as automated as possible.
  • If for some reason the burner flame goes out, it will re-ignite.
  • Easy to operate and maintain.
  • Have a long service life ( from 15 years old).
  • Allows you to control the temperature in the house down to one degree.
  • The use of such boilers is safe.
  • The devices are compact.

Cons gas boilers:

  • It is not economically feasible to place these devices in houses with an area of less than 100 m2, their use in such conditions is considered extremely dangerous.
  • Installation of gas boiler equipment requires preparation of the necessary documentation (you need to obtain permission from Gaztekhnadzor).
  • It is necessary to install a chimney to remove exhaust gases.
  • The room in which the boiler is installed must have a separate exit to the street and forced air ventilation (especially for boilers with an open combustion chamber).
  • When gas pressure is low or the burner fails, the efficiency of the device drops sharply.
  • The installation of expensive automation is required to ensure security control.

The most profitable option is to install a gas boiler in a house connected to the main gas supply network. From the central pipe, a connection is made to the house directly to the heating equipment, which allows you to completely forget about the issue of heating the room, energy delivery and operating costs. These heating systems comply with all modern environmental standards.

The autonomous gas heating system includes gas tank or gas cylinders. It is advisable to plan the installation of a gas tank on the site and take it into account during development.

This will make it possible to install a gas pipeline underground to the boiler room and kitchen. The use of cylinders is practically unlimited.

When calculating the efficiency of heating private houses with liquefied gas, it is necessary to take into account that one 50 liter cylinder accommodates 35-42 liters of gas. Heating consumption 100 sq. m. per day for any boiler is equal 15 l. It is also necessary to remember that cylinders are refilled once a week. Heating a house with gas cylinders can be considered profitable subject to the following conditions:

  • The house area is smaller 100 sq. m.
  • The building has good insulation.
  • The gas boiler is a backup.
  • In the future, gasification of the settlement is planned.

How to make a heating system with your own hands

In a private house, you can install a gas heating system with your own hands. This requires:

  • make the necessary thermal and hydraulic calculations;
  • draw up a working draft with a gas heating diagram;
  • purchase materials and equipment;
  • carry out installation;
  • test the heating system under increased pressure;
  • put into operation.

When developing a gas heating scheme, the following are determined: coolant circulation: they decide whether she will be natural or forced. An important point is also the choice of single-pipe or two-pipe heating circuit wiring.

After selecting the heating scheme and piping you can calculate the required power boiler, circulation pump and radiators, as well as determine the diameter of the pipes, the number and their sizes.

Types of boilers

Having decided on the power of the gas boiler, we begin to select the device.

Regardless of the type of boiler, the owner’s main task is to ensure the efficient operation of the most important communication system at home with minimal financial and labor costs.

Equipment installation

The installation of the heating system begins with the installation of the boiler.

Required Tools for installation of a heating system:

  • roulette;
  • perforator;
  • level;
  • flarer;
  • gas, adjustable and regular wrenches;
  • screwdriver or screwdrivers.

For fastening use 4 screws with diameter 6-7 mm. Using a level, check the accuracy of the installation. After this, a connection is made to the water supply using a coarse water filter. Install ball valves. Attach the chimney.

Attention! Connect the boiler to the gas pipeline only a specialist should.

After installing the gas boiler, they proceed to laying the pipeline according to the diagram. There are three types of pipes used in heating systems:

  • metal;
  • metal-plastic;
  • polymer.

Best suited for the heating system of a private home plastic pipeline. He is not afraid of changes in temperature and pressure. Its installation is carried out using a special kit that allows you to reliably solder the system elements.

Radiators are selected taking into account the required power. Batteries made from different materials are available on the market:

  • steel;
  • cast iron;
  • aluminum;
  • bimetallic.
