All about gas heating boilers for a private home. Floor or wall, which is better?

Heating of a private house is being arranged different ways. The traditional stove stove, used in Russia for centuries, is gradually losing its position. The electric and gas systems much more relevant today.

At the same time, electric heating requires large financial costs, so installing it in large rooms is unprofitable. In this case, an excellent solution is gas heating, in which the main carrier of heat energy is a gas boiler. When there is a gas main in the area, this type of heating is the least expensive.

In addition, it can be considered one of the safest types of heating.

Heating for a private home

The production of gas boilers provides several equipment options. The difference primarily concerns functional features.

There are two types of boilers here:

  1. Single-circuit.
  2. Dual-circuit.

1. Single-circuit

This type is intended for a heating system. It's quite compact. Its design provides for heating the coolant that circulates in the heating system. It has several connectors with which it is possible to supply hot water.

In this case, the water heater is selected taking into account household needs and, accordingly, the boiler model. In this case, it is the boiler that maintains the set temperature. An automatic system allows you to regulate this process. In the warm season, the gas boiler is switched to “summer” mode and the heating function is turned off.

Single-circuit models have a number of advantages that make them more popular:

  1. automatic adjustment allows you to set the optimal level of heat supply, which allows you to save on fuel;
  2. single-circuit boilers involve the creation various schemes heating system, with which you can increase power and extend service life;
  3. the design of such devices is quite simple and at the same time quite reliable;
  4. installation of a single-circuit model is not particularly difficult.

Their only drawback is the lack of an independent system for supplying hot water. For these purposes, a water heater heat exchanger is connected to the boiler.

2. Double-circuit

This type of design provides for the presence of two circuits, each of which performs its own specific function. One circuit is intended directly for heating. The second one performs the function of a water supply system; with its help, hot water enters the water supply system.

In this case, two modes are possible:

  1. Flow-through– water heats up during consumption. At this moment, the heating circuit is closed without affecting heating;
  2. Boiler room– used if the demand for hot water is higher. To do this, a boiler is installed, the boiler heats the water in it to the required temperature. For small water heater volumes, this option can be considered more economical.

According to their design features, double-circuit boilers are divided into two types:

  1. Biothermal with one heat exchanger, consisting of two tubes located one inside the other. Inner pipe designed for the passage of water for plumbing, external - for heating;
  2. Duothermic with two heat exchangers, each of which has a copper tube in its design that transfers heat. In this case, one of the heat exchange systems is responsible for heating, the second for heating water in the water supply. This type of boiler is more economical. But heating is somewhat slower.

Among the advantages that double-circuit gas boilers have, it is worth highlighting the following:

  1. This equipment is equipped with a protection function in case of power surges.
  2. Fast water heating; when using 5-6 liters per minute, the water temperature heats up to 37 degrees.
  3. The presence of a sensor to shut off the gas supply in the event that the flame goes out, which ensures the safety of their use.
  4. Compact, yet highly efficient.

The disadvantages of double-circuit gas boilers arise precisely from the design features:

  1. This type of equipment provides full supply of hot water to only one point. When the tap is opened at one more point, the water temperature drops.
  2. Water heating occurs only after main pipe cold water will flow out.
  3. When water is supplied to the water supply system, the water supply to the heating system is turned off.
  4. Hard water can damage the heat exchanger.

Classification of gas boilers is also carried out according to such a parameter as the removal of combustion products.

In this regard, two types of equipment can be noted:

  1. Traditional.
  2. Condenser.

In the first case, the heat of combustion of the fuel is considered lower, and gases and vapors escape into the atmosphere.

Traditional or convection boilers have in their design:

  1. Modulating burner.
  2. Expansion tank.
  3. A reservoir where condensate collects.
  4. Temperature sensors.

In addition, this equipment provides some additional functions:

  1. Self-diagnosis.
  2. Protection against scale formation, blocking and freezing.

Such models have their advantages:

  1. Thanks to its fairly simple design, installation of the equipment is easy.
  2. Low cost.

But it should be noted that the energy in this type of boiler is not completely used.

Capacitor equipment has much greater efficiency. This is due to the fact that some of the vapors and gases formed during fuel combustion enter the boiler system and condense in the heat exchanger. The resulting heat enters the device.

Thus, among the advantages of this equipment, the following are especially worth noting:

  1. Fuel economy.
  2. High efficiency.
  3. Efficiency from 80 to 97%.

But these devices also have disadvantages:

  1. Higher cost.
  2. Complexity of design.
  3. Repair and maintenance of these models require a certain investment of time and money.

Gas boilers also differ in installation method:

  1. Floor-standing.
  2. Wall-mounted.

Floor-standing gas equipment is made of cast iron and is quite cumbersome. To install it, it is necessary to provide a separate room with an area of ​​about 9 sq.m. But at the same time, their main advantage is greater power. It is advisable to use them for large premises where greater heat transfer is required. Durability is another plus of these devices.

Wall-mounted boilers are made of steel, lighter and more compact. At the same time, they are quite resistant to various mechanical damage. They do not require much space to install. This is an ideal option for heating small spaces. But unlike floor-mounted ones, their power is somewhat lower.

The disadvantage of such boilers is their shorter service life than floor-standing ones. This is due to the material of manufacture.

Some of the advantages are ergonomics and safety.

Boiler selection

When choosing a boiler, every homeowner is guided, first of all, by two points - fuel economy and reliable automation. The latter will ensure safety in the event of a shutdown of the central gas supply or any malfunctions in the operation of the device.

But when choosing equipment, it is necessary to take into account other factors that greatly influence the quality of heating.

  1. House area. Depending on this indicator, power is selected gas boiler. Here we can distinguish three main categories of devices:
    • Boilers with a power of up to 65 kW are used for small areas. Most often this is a wall-mounted type of equipment.
    • Power up to 1700 kW is applicable for two-story and multi-apartment buildings;
    • Devices with a power of up to 15,000 kW are used only in industrial and industrial premises. It follows that the larger the heated area, the greater the power of gas equipment should be. The calculation is taken next indicator– 1 kW per 10 sq.m. In double-circuit boilers this parameter is approximately 30% higher.
  2. The placement option is selected based on power. Wall-mounted boilers have less power. Therefore, if the total heated area is small, a wall-mounted boiler will be an excellent solution not only for heating, but also in terms of design. In large rooms it is necessary to install more powerful floor-standing devices.
  3. The next factor is the purpose of the boiler. If, in addition to heating, hot water is supplied to the water supply system, dual-circuit modifications are used. The best option in this case there will be a boiler with a built-in boiler. Single-circuit models are provided only for the heating system.
  4. The type of burner is of great importance:
    • Atmospheric is designed specifically for the heating system of private houses.
    • Ventilation is used mainly in industrial buildings.
  5. Another point to pay attention to is the type of traction. There are two options here:
    • Natural with the obligatory presence of a chimney. The design of such boilers has an open combustion chamber. These models are cheaper, but their efficiency is somewhat lower;
    • The forced exit of combustion products is carried out through a turbine chimney, the main element of which is a fan. In this case, a coaxial pipe can act as a chimney. These models are equipped with a closed firebox. Due to the sufficiently high efficiency, significant savings are achieved.

In addition, when choosing, you should be guided by the following recommendations:

  1. The design power parameter should not be higher than necessary.
  2. Burners made of stainless steel will last much longer.
  3. Pipelines must be made of stainless steel or bronze.
  4. Availability of an automatic control system.
  5. Kit automatic protection will ensure safety in any unforeseen situations - lack of traction, gas leak, disappearance of flame.
  6. In case of existing problems with the heating system, it is better to choose a double-circuit boiler.
  7. And, of course, when choosing, you should focus on the manufacturer. Today, in this regard, several options can be distinguished.

What is a gas boiler

This is a device used to generate thermal energy for space heating for various purposes and heating water for household and other purposes through gas combustion. Such boilers are widely used for domestic purposes, for example, for heating a private house. You can order a heating boiler for a private home in a specialized online store with delivery by mail to Moscow, St. Petersburg or another city in the country. Remember that gas is a flammable and explosive fuel, so it is important to follow safety precautions.

The principle of operation of a gas boiler is that when fuel is supplied to the device, the piezoelectric ignition is turned on. The spark subsequently ignites the igniter. Supplying fuel to the burner when the igniter is not lit is unacceptable, because gas may explode. The igniter ignites the main heater, which heats the coolant in the boiler to the temperature set by the thermostat. When the desired parameter is reached, the automation turns off the burner. When the temperature in the device drops, the temperature sensor commands the valve to supply fuel, and the burner lights up again. Classification:

  • by location: floor and wall;
  • By functionality: single- and double-circuit;
  • by type of traction: natural and forced;
  • by type of ignition: with piezo ignition and with electronic ignition;
  • according to the complete use of fuel energy: convection (traditional) and condensation.

How to choose a gas boiler for heating a private house

To purchase the best gas boiler for heating a private home, you need to take into account several important criteria. The choice of a suitable device depends on the total area of ​​the heated room, the need to heat hot water and the number of its consumers, the presence of a chimney and the pressure in the gas pipeline. Additionally, you need to take into account the presence of insulation on the walls. Browse online catalogs with photos and take into account the following tips:

  • Wall-mounted or floor-standing gas boiler. The choice of heating equipment for a private home must begin with the selection of a place for its installation. If you have space for a separate boiler room, then you can choose a floor-standing device, otherwise limit yourself to a wall-mounted modification. A floor-standing boiler is often made on the basis of a reliable cast-iron heat exchanger - this model has a significant margin of reliability, it is unpretentious and does not cause problems in operation. Floor-standing equipment for private homes has high power. The wall-mounted analogue is compact - it is ideal for heating a small object.
  • Single-circuit or double-circuit equipment. Single-circuit equipment is widely used to heat a private home. It's very different simple device– it has a heating pad and one heat exchanger. The double-circuit modification combines a boiler and a gas instantaneous water heater. Its design is more complex, but at the same time it is more functional and easier to install.
  • WITH natural ventilation or forced. In the first case, the hood passes through the chimneys available in the house, in the second, the unit has built-in fans that remove waste gases from the boiler and remove them outside.
  • With open or closed combustion chamber. To ensure that the choice of a gas boiler for a private home is optimal, pay attention to the type of combustion chamber. A model with an open chamber is often called “atmospheric”, because. air flows to the burners by gravity directly from the room. Combustion products are removed through a chimney with natural draft. This option has a simple design and low noise level. A turbocharged gas boiler for heating private houses has a closed combustion chamber and fans for removing smoke and air intake. It requires electricity to operate. It has a complex design and high noise level.
  • Heat exchanger material. This element can be cast iron or steel. The first option is more durable, because... not subject to corrosion, but more fragile. New models use gray cast iron, which makes them more durable and less brittle. A steel heat exchanger is lighter, but it is susceptible to corrosion.
  • Supercharged or atmospheric burner. The first installation is characterized by high efficiency, good power, but is expensive. The second option is more affordable in terms of cost, but low-power. A forced-air burner must be purchased separately, but an atmospheric burner is included in the package of the gas boiler.
  • Convection or condensation model. Gas boilers for heating a private home are often built using a convection design. In this case, the burner generates thermal energy, and the heat exchanger takes the resulting heat, which is sent to the system - its remains go outside. The efficiency of such devices is 90-93%. For condensing units it is slightly higher. The scheme of their work is as follows: in heating system Almost all the generated heat is taken away, resulting in condensation that is sent to the drainage.
  • Piezo ignition or electric ignition of the burner. In the first case, the ignition process is manual, in the second - automatic.
  • Assess the safety of operation. Many modern gas heating boilers are equipped with sensors that monitor the operation of the unit at all stages - from the supply of water and gas to the removal of exhaust gases to the outside. They are capable of blocking the heating system if the electricity suddenly goes out or blocking the boiler if the temperature exceeds the established norm. For such sensors, constant availability of electrical power is important. Eat floor installations, the sensors of which operate in mechanical mode, regardless of the power supply.
  • Calculate the power. To heat 10 m2 of living space in the domestic climate, you need about 1 kW of thermal energy. In the Far Eastern and northern regions this figure increases to 1.2-1.5 kW, in the southern regions it ranges from 0.8 kW. Don't forget about the reserve that is needed in case of excessively cold winters and heat losses. It is usually 10-20%.

Mains gas is the cheapest type of boiler fuel. If the village is gasified, then the owners of the cottages often simply do not look towards other options. In this case, gas boilers for heating a private house - optimal solution. They are economical, easy to maintain and reliable. However, you need to choose this equipment wisely. Models with different characteristics and there are many manufacturers on the market.

  • Types of heating boilers for a private home

    The main criterion for choosing a gas boiler is power. It is determined by the home’s need for hot water for the heating system and water supply. It is not difficult to calculate it using average formulas for a specific house. But before you go to the store for boiler equipment, you need to analyze a lot of nuances. This equipment has a lot of different design features and additional options.

    To choose the right gas boiler model in a private house, you need to decide in advance:

      What is more important – high efficiency or simplicity and reliability of the design;

      With its location (on the floor or wall);

      How many circuits are required (one goes for heating, the second for hot water supply or “warm floor”);

      What material should the heat exchanger be?

    The answers to these questions will allow you not only to choose the best option, but also to estimate the cost of the equipment in advance. The more power and automation a boiler has, the more expensive it is. Here, as when considering different types of roofing for the roof of your house, you will have to look for a middle ground. Some options are cheaper, but not as durable. And other roads, however, are often redundant in terms of characteristics.

    By location

    The gas boiler can be mounted on the floor or wall. Floor-standing models are more bulky, but in most cases they have much higher power. Wall-mounted equipment is most often low-power (up to 40 kW) compact units. If the house is large in area, then you will have to purchase a device to heat it. increased power, installed on the floor. There are no options here, but for an apartment a small instantaneous water heater on the wall is more suitable.

    Floor model

    Most wall modifications come with cast iron heat exchanger. Cast iron is heavy, but reliable. Coils made from it have a considerable margin of safety. And heating boilers with them are more unpretentious and cheaper than other options.

    Mounted option

    According to the operating principle

    Conventional gas boilers operate using a convection system. In them, the burned methane releases heat, which is sent to the heating system using a heat exchanger. In this case, the exhaust gas escapes by convection upward into the chimney, taking with it part of the thermal energy along the way. The efficiency of such boiler equipment is about 80–90%.

    However, there are also condensing boilers that run on gas, for which manufacturers indicate the power in their data sheets in the range of 105–110%. The fact is that in heating engineering, efficiency is usually calculated from the lower calorific value of the fuel. That is, the thermal energy going into the chimney is simply not taken into account.

    But in condensation gas boilers the exhaust is first sent to the recuperator. In it, combustion products are cooled and released useful heat water before going down the chimney. This energy is not enough to fully heat the coolant in the radiators. However, the return water is quite enough to heat the water.

    As a result, the coolant that has cooled down in the heating radiators of the house, before entering back into the boiler furnace, is first slightly heated in the recuperator. So the overall efficiency of such units goes beyond one hundred percent.

    A condensing boiler is more efficient than a convection boiler. However, it is more complex in design and will break more often. Plus, the resulting condensate is a weak acid. If the sewage system in a private house is autonomous, then condensation equipment will have to be abandoned. You cannot drain acidic condensate into a septic tank; all microflora in it will instantly die.

    By type of work

    The simplest and cheapest gas boiler for heating a private home is a single-circuit one. It is made in such a way that all the water heated inside is sent exclusively to the heating circuit. This device has one burner and one heat exchanger.

    The dual-circuit option is a combination of two units in a single housing. Part of this gas boiler works to heat the coolant for batteries, and part of it works to heat water for hot water supply. It is more complex in design, but more compact and cheaper than two separate devices. If you plan to use gas not only to heat the house, but also to heat water for plumbing or “warm floors,” then you should select a dual-circuit model.

    By modification

    The classic design of gas boilers provides an open gas combustion chamber. Wood-burning stoves and fireplaces work in the same way. All fuels require oxygen to burn. In the case of an open firebox, it is taken directly from the room where the boiler is located. After combustion products using natural traction They pull themselves out into the street through the chimney.

    A closed chamber requires the presence of a forced air pump. Boilers with it have a higher efficiency, but they also cost much more. At the same time, they need a constant power supply. Without power supply, such equipment will not work and heat the coolant for heating a private home.

    Gas heating boilers with an open chamber are energy independent and cheap. However, if the ventilation is poorly designed, the room with them may lack oxygen. This should not be allowed even in a boiler room, and in a residential area it is generally dangerous for household members. Plus, equipment with a closed chamber is also noisy; you shouldn’t expect complete silence from a running fan.

    According to heat exchanger material

    The heat exchanger in a floor-standing and wall-mounted boiler can be made of:

    • Bimetal.

    Copper heat exchangers are the most efficient in terms of heat transfer, but also the most expensive. The cheapest ones are reliable cast iron analogs that are ready to last up to half a century. However, they are the heaviest and most massive. Steel and bimetallic options are the golden mean when choosing between characteristics and cost.

    Advantages and disadvantages of a gas boiler

    Among the main advantages of gas hot water boilers are:

      Minimum effort when supervising the operation of the equipment;

      Economical heating of a private home due to low cost of fuel;

      Easy to put the boiler into operation;

      Long period between scheduled inspections and maintenance (once a year is enough);

      Availability of non-volatile models.

    The gas boiler is designed in such a way that everything in it works on its own without human intervention. I pressed the “ON” button and an electric discharge went to the burner, which ignited the gas. As a result, the cottage immediately began to heat up.

    The disadvantages of the heating boilers under consideration are as follows:

      Explosiveness of methane (propane-butane in the case of using a gas holder);

      The need to prepare a package of permits;

      Mandatory conclusion of a gas equipment service agreement;

      In some cases, it will be necessary to install a separate boiler room.

    Choosing a gas boiler for the required parameters is not difficult. Much more difficulties arise with its connection to networks. These are not soft tiles or foam blocks, which do not require any approvals. Boiler equipment belongs to complex systems. It must be checked and serviced by a specialized company. Plus, before installing it, you also need to request technical specifications from gas workers and prepare a project. It often takes up to a year to resolve all these issues.

    Comparative savings of boilers using different types of fuel

    Boiler power calculation

    Based on the required power, a boiler for a private home is most often selected based on a simplified calculation - for every 10 square meters of area you need 1 kW of thermal energy. For the northern regions, an increasing factor of 1.5–2 is applied, and for the southern regions a decreasing factor of 0.7–0.9 is applied. Plus, about 20% of the capacity is set aside in reserve and 20–25% for hot water supply. But all these are average figures.

    In a complete thermal engineering calculation, you will have to take into account:

      Design features of external walls (thickness, material, degree of insulation);

      The presence of windows and the level of thermal insulation of the attic;

      Heat loss through the roof, foundation and ventilation;

      Maximum possible and average outdoor temperatures in the region;

      Availability of “warm floor” and hot water supply;

      Number of batteries;

      The configuration of the heating system as a whole and much more.

    Only an experienced designer can make such a calculation correctly. When choosing a gas coolant heater for heating yourself, it is best to focus on the figure of 1 kW per 10 sq.m. This way the probability of error will be minimal.

    Manufacturers of gas boilers

    How to choose a boiler

    At first glance, choosing a gas boiler for your cottage is a real hassle. It is necessary not only to calculate the power, but also to decide on a bunch of parameters. However, without careful analysis, the choice of such water heating equipment can end in failure. If the equipment turns out to be too powerful, it will simply run idle, or at peak load it will not have enough operating pressure in gas pipe. A unit with insufficient power may even break down.

    For a small house or apartment, it is best to take a wall-mounted model with a steel heat exchanger. It will be inexpensive and with proper performance parameters. To organize heating in a large cottage, you will have to equip a boiler room. The best option in this case is a floor-standing boiler with a cast iron heat exchanger.

    Equipment with an open chamber is energy independent and does not make noise, but gradually burns oxygen in the room where it is installed. Plus, she only needs a vertical and high chimney. If the ventilation in the room is at permanent job gas burner is not designed, it is better to choose a closed analogue with forced air draft.

    When choosing specific model It is important to look at the presence of safety elements in the boiler. The gas is explosive. If the equipment is not equipped with automatic shutdown of the fuel supply and automatic ignition during extinguishing, then it is better to abandon such equipment immediately.



    • When choosing a gas heating boiler for a private home, take into account several nuances related to installed system heating, technical characteristics buildings, and the actual needs for heat and hot water. A wide range of products offered by domestic and foreign manufacturers will allow you to select a boiler that is optimally suited in each specific case.

    Types of gas boilers for private housing construction

    Modern gas boilers for heating and hot water supply to a private home are developed taking into account the operating characteristics. Has been modified internal organization to make gas combustion as economical as possible and increase thermal efficiency.

    Not every gas boiler installed in a private house will work equally efficiently and provide better heat transfer. When deciding whether to purchase a heat generator, several parameters are taken into account:

    • Type of heating system in a private house with a gas boiler - for classic boilers, radiator heating is suitable, some modern models will work effectively only when connected to heated floors.
    • Fuel type - economical gas combustion and high heat transfer - are the main criteria for choosing boiler equipment. High efficiency and thermal efficiency are especially important when operating on liquefied gas. If it is planned or, special attention is paid to the efficiency of boilers.
    Produced boiler equipment, are classified according to three operating parameters: type of placement, combustion chamber configuration, number of circuits.

    By accommodation type

    The selection of a gas boiler for a private home begins with choosing a unit according to the type of placement. There are wall-mounted and floor-mounted models. Each has its own characteristics and differences:
    • A wall-mounted boiler is usually energy-dependent. To facilitate the design and reduce the load on load-bearing wall, designers resort to various tricks. Weight is reduced through the use of metal alloys and a bithermal heat exchanger.
      In the design of a dual-circuit unit, it is often built in storage capacity for heating water.
      Wall-mounted single-circuit gas boilers for heating a private home do not have such a modification. Models with one circuit are intended exclusively for heating, but if necessary, it is possible to connect a remote tank for heating DHW.
      The advantage of wall-mounted units is space saving, the ability (for some models) to be built into a kitchen cabinet, as well as easy connection to the heating system.
    • A floor-standing gas boiler is not limited by performance, like its wall-mounted counterparts. Available in single-circuit and double-circuit versions, with a heat exchanger made of steel and cast iron. The floor-standing design is not always convenient, especially if the boiler is installed in the kitchen, where there is not always enough space even without heating equipment.
    When deciding which boiler to choose, wall-mounted or floor-mounted, they are primarily guided by the area of ​​the heated building. It is better to heat a house over 250-300 m² with a floor-mounted heat generator that has better power characteristics. Floor-standing boilers cost less, but they take up a lot of usable space.

    By type of gas combustion chamber

    By design, combustion chambers distinguish three configurations of heating equipment, differing in efficiency and installation requirements:

    When choosing a boiler based on the design of the combustion chamber, they take into account the dependence of the boiler on the presence of voltage in the network, the type of heating system and the fuel that they plan to use.


    By number of circuits

    Despite the abundance of various modifications, the consumer is still offered single-circuit or double-circuit boilers, but with the presence of certain additional functions(built-in boiler, etc.). Each decision has its positive and negative sides:


    A double-circuit boiler is chosen when, in addition to heating, there is a need to obtain hot water. If there is no such need, install a single-circuit heat generator.

    How to choose a gas heating boiler for a private home

    The choice of a gas boiler for heating a private home, in addition to the design and operating parameters, is influenced by several other factors:
    1. Power.
    2. Manufacturer.
    3. Price.
    It would not be amiss to find out how those who have been operating the boiler for some time feel about the chosen model of boiler equipment, and also to take into account the opinion of consultants offering heating equipment. All these factors will help you choose the optimal boiler that fully meets your needs.

    How to calculate boiler power

    Calculation of the power of a gas boiler for heating a private house is carried out in several ways. But, as practice shows, the most common calculation methods are:
    • Calculations using online calculators were originally developed for consultants to make calculations and boiler selection easier for clients. On this moment, many sites for the selection of heating equipment have it available to all visitors. When selecting, you will need to enter information about the area, degree of thermal insulation, the presence of window and door openings, and much more.
    • Independent calculations - you can calculate the approximate power of the boiler using the simple formula 1 kW = 10 m². Calculations will show an inaccurate value and will require power adjustments, taking into account the required margin for cold winter and DHW needs.

    Which company to choose a boiler

    The best gas heating boilers for country houses are made by European manufacturers. The largest concerns are located in Germany, France, Italy and the Czech Republic. In the rating of boilers, domestic models of heating equipment occupy not the last positions.

    Below is a list of the most popular models based on sales and searches. For convenience, the offered brands of boilers are distributed depending on the company and operating principle:


    The most economical boilers use the principle of condensation heating of the coolant. Condensing models are produced exclusively by European companies.

    Low temperature heating mode is not suitable for heating houses located in northern latitudes. Installation of condensing boilers is advisable in mid-latitudes, in mild climates.

    The cost of a boiler for a private house

    Prices for gas boilers for heating a private home vary depending on the manufacturer, combustion chamber, number of circuits and thermal characteristics. The most expensive purchase will be a condensing heat generator offered by the leaders in the production of heating equipment, the German concerns Buderus and Viessmann, as well as the French company De Dietrich.

    For comparison, prices for double-circuit gas boilers for heating country house, from the Russian company Neva Lux, is approximately 2 times cheaper than a similar Viessmann and 1.2-1.5 for the Italian Baxi. But, if you consider that gas consumption in European-made heat generators is 15-20% less, all extra costs will pay off within 3-5 heating seasons.

    If you have a gas main near your house, then the best and most cost-effective solution would be a gas boiler. And in order for your equipment to work smoothly and properly, you need to know how to choose gas boilers for, what criteria and parameters need to be taken into account. Our review will help you understand the existing variety of models and make the right choice of a functional and convenient design.

    Areas of application of gas boilers for heating and hot water supply to a private home: types, pros and cons of designs

    If you can find a good one for a private home, then it can become profitable solution Compared to - they are not particularly convenient to use, but are too expensive.

    Here's why you should choose a gas unit:

    • automated work that does not require your constant attention and control;
    • fuel is not as expensive as, for example, electricity;
    • you can start the unit at any time, and no preliminary preparation is required;
    • at proper care operation will be safe;
    • high level of efficiency;
    • Gas equipment can only be serviced once a year;
    • For the device to work, you do not need to provide access to electrical networks.

    The correct choice of unit will allow you to heat even houses with large area. If there is no gas line, then you should not ignore the use of gas cylinders. But this method requires special caution. For example, cylinders can be installed outside the house, and a special pipe can be installed from them. They must be covered from the outside. Most often, metal fences are used for this.

    It is worth studying some of the disadvantages of such units:

    • to connect to the gas line, a special permit is required;
    • you need to consider the possibility of regular maintenance;
    • gas leakage must not be allowed, as this will lead to an explosion;
    • There are certain types of boilers that require a separate room.

    When choosing a suitable device, pay attention to the heat exchanger. It can be steel, copper, cast iron or bimetallic. Copper options are known for ease of use. If they break, they can be easily repaired. If you value practicality, then the best solution bimetallic or steel heat exchangers will become.

    The most reliable options include cast iron models, which heat up quickly and are resistant to corrosion. Such heat exchangers are more often used in floor structures.


    Boilers can be double-circuit, single-circuit, convection, wall-mounted, floor-mounted and condensing. But that’s not all that such equipment can differ in. There are also some design features:

    • the automation system can be in the form of mechanical control or based on electronic modules;
    • The necessary piping of units includes expansion tanks and all kinds of security systems;
    • thermostats, modules can be used as control mechanisms remote control and special control panels;
    • some models are provided with different capacity volumes. These tanks allow you to store supplies of heated water for a certain period of time.

    Let's consider the main classification of gas devices. Here are the main categories:

    • According to the installation method, the equipment is divided into wall-mounted and floor-mounted models;
    • for heating liquids into single-circuit and double-circuit;
    • According to the options for removing combustion products, the structures are turbocharged and chimney.

    Wall variations appeared not so long ago. Everything is located inside the case necessary elements: expansion tank, pumping equipment, pressure gauge, heat exchanger and thermometer.


    For your information! It is gas equipment that is the most budget option for organizing high-quality heating.

    Gas boilers for heating a private home: how to choose the best option

    The choice of a gas boiler for heating a private house is influenced by such a parameter as power. Wall products have the most maximum rate- 60 kW, and for floor-standing ones it can be more than 100 kW. Also, when deciding on a model, it is worth considering factors such as cost and manufacturer. If there is no highway, then liquefied gas. In this case, you can choose a boiler with a burner.


    Also look at the prices of gas boilers for heating a private house up to 100m2. This parameter depends on the manufacturer, construction material and additional functionality.

    Wall-mounted models can have two types of burners: turbocharged and atmospheric. Gas boilers can also be condensing. They can be used at low temperatures. In this case, the gas is not consumed so quickly due to vapor condensation.


    For your information! To choose suitable option Read the reviews first and study the opinions of experts and characteristics of different models.

    Where to install the equipment: wall-mounted and floor-mounted gas boilers

    The choice of equipment begins with the selection of placement options. You can purchase models of gas boilers for floor heating and wall type. The two varieties have certain differences and features:

    • wall devices do not depend on electricity. To prevent the unit from creating a large load on the wall, production tries to reduce its weight using different alloys. Such models will appeal to those who want to save more space; for example, they can be built into a cabinet in the kitchen. In addition, many people like the easy installation of wall-mounted gas boilers;

    • floor devices may have unlimited performance. There are double-circuit and single-circuit models with heat exchangers made of cast iron and steel. Such a device will take up a lot of space, so its installation should be thought out in advance. Depending on the configuration, the device may have an atmospheric or turbocharged burner.

    Floor-standing models are often equipped with cast iron heat exchangers. Wall options are compact. The price of a wall-mounted double-circuit gas boiler for heating a private house depends on the material of manufacture.

    For your information! When choosing the appropriate option, consider the area of ​​the building. If the house is more than 200 sq. m., then it’s better to choose floor unit. At the same time, the price of a floor-mounted double-circuit gas boiler for heating a private house will be less than its wall-mounted counterparts, but they require a lot of free space.

    Equipment and number of circuits

    Gas units can be double-circuit or single-circuit. Each option has some advantages and disadvantages:

    • The operating principle of a double-circuit gas boiler is based on the mode. This option is used for heating and water heating. Most often it is equipped with two heat exchangers. To reduce weight, the equipment is equipped with a bithermal heat exchanger that operates in an interchangeable heating mode;

    • a unit with one circuit is equipped for heating the coolant. In the future, you can convert the design of a single-circuit gas boiler with a boiler indirect heating.

    Gas double-circuit boilers for heating a private home are much more compact, which allows them to be used in rooms with limited space. In double-circuit designs there is a boiler and a gas one. If the DHW circuit is running, the heating function is switched off.

    Single-circuit models are larger and have more complex installation. If a boiler is additionally used, the design can be equipped with circulation pumps. Devices with one circuit are equipped with a heat exchanger and burner.


    Types of combustion chambers

    In gas boilers, an open and closed combustion chamber is installed depending on the equipment option. There are three configurations:

    • atmospheric units They are highly reliable and have a simple design. There is an open combustion chamber inside. In order for the gas to be burned, air is taken from the room. Regulation is carried out using thermomechanical regulators. When choosing them, remember that the disadvantage of such devices is significant gas consumption and special installation requirements. But at the same time, the efficiency of the device is not so high;

    • turbocharged model A floor-standing gas boiler with a closed combustion chamber is equipped with two fans, for gas removal and for air supply. In this case, these processes are carried out forcibly, which is called using turbines or fans. Many people prefer such units because of their efficiency. Gas consumption can be reduced by 20-30%. In this case, the efficiency reaches 95-98%, but noise may be felt during operation;

    • to the very economical options worth mentioning condensing wall-mounted double-circuit gas boilers with a closed combustion chamber. Their efficiency can reach 109%. The device is equipped modulating burner. These models are non-volatile. The heat exchanger contains a condenser or unit responsible for collecting condensate. The units operate on liquefied or natural gas. They are used for connection to low temperature structures.

    At home, equipment often operates according to a convection scheme:

    • the burner produces thermal energy;
    • the heat exchanger takes the heat;
    • the heat moves into the heating system, and the remainder is released into the atmosphere.

    How to calculate the power of a gas boiler

    • calculations using an online calculator. In this case, you need to enter the area, the number of window and door openings and the level of thermal insulation;
    • the approximate power can be found using the approximate formula - 1 kW = 10 kW. m.

    However, this indicator may vary depending on climatic conditions. For northern regions it is 1.3-1.5 kW, and for southern regions it is approximately 0.8 kW. Important to consider heat losses, which are influenced by the following factors:

    • window structures;
    • insulation of the attic or heated second floor;
    • Availability ;
    • the presence of external walls;
    • ratio of floor to wall area.

    How to properly replace old equipment with new one: installation nuances

    Over time, replacement may be required as it becomes obsolete and its efficiency decreases. If the efficiency of the equipment has decreased, the unit is noisy and smokes, then this is a sign that it needs to be replaced.

    • if the walls are lined with flammable materials, then a layer of some kind of fire-resistant material is installed between the unit and the wall;
    • the minimum distances from the device to the walls and ceiling must be at least half a meter, and to the floor - 0.8 meters.

    Before installation work and launching equipment, it is necessary to obtain permits.

    How to connect the boiler and features of installation work

    Installation of a gas boiler in a private house is carried out using different schemes connections. Two pipes for coolant can be connected to a single-circuit device. In this case, the coolant will flow through the system and return for additional heating.

    When using an additional boiler, a connection via . While the water is heating up in the boiler, the coolant stops circulating. How long it will take the boiler to warm up depends on the size of its container.


    The connection diagram for double-circuit gas boilers is due to the presence of two heat exchangers. In this case, the main one heats the water for heating, and the second heats the water for water supply. 5 pipes are connected to this design. Coolant pipe, cold water line, gas, with hot water and with hot coolant.


    The connection to the gas source is carried out by gas workers. In this case, it is necessary to install shut-off valves to shut off the gas. also in mandatory a special filter is installed. A pipe from the boiler runs through it, which should be made of stainless steel. The line is mounted to the pipe using a union nut. All joints must be sealed.

    Particular attention should be paid to equipment automation, as this will not only ensure safety, but also save on fuel.

    Important information! To check the tightness of the equipment, all joints are treated with a soap solution.

    How to choose a voltage stabilizer for gas boilers

    For a gas boiler it depends on the following parameters:

    • response time affects the quality of equipment automation. This indicator means how quickly the stabilizer can adjust the voltage;
    • The voltage range is important, indicating within what limits the rectifier operates. When a certain value is reached, the mechanism turns off the equipment;
    • the degree of correction affects the stability of the output voltage;
    • The operating temperature range is +5 - + 40 degrees.
