*Overview of the best in the opinion of the editors of the site. About selection criteria. This material is subjective, is not an advertisement and does not serve as a guide to purchase. Before buying, you need to consult with a specialist.

In Russia, gas is the most affordable type of fuel. That is why the owners of houses, cottages and small businesses prefer to heat the premises with a gas boiler. The old Soviet cast-iron devices have been replaced by elegant and lightweight models. Foreign brands have penetrated the domestic market, which are seriously competing with Russian equipment. On the one hand, the range of boilers has expanded, and on the other hand, buyers have problems choosing the right model. Expert recommendations will help you find gas boilers in the sea best option for your home.

How to choose a gas boiler

1. The number of contours. The choice should begin by determining the number of contours. Single-circuit models are able to provide heat to the heating system. To heat the water, you will have to buy an additional boiler. But double-circuit boilers simultaneously heat the house, providing residents with hot water.
2. Installation. According to the type of installation, floor and wall devices are distinguished. Floor-standing models boast higher power. However, they are bulkier and heavier. Wall-mounted boilers look more elegant, they save space in the boiler room, which is important in cramped back rooms.
3. Power. The most important parameter of the heating device is thermal power. For houses with good insulation and standard rooms (height 3 m) it is customary to determine the power indicator using a simple formula. With the help of 1 kW of heat energy, an area of ​​​​10 square meters can be heated. m. In old houses with poor thermal insulation, it is necessary to install a boiler, the power of which is 20-50% higher than the calculated one. A double-circuit boiler is also selected by about 20% more powerful so that the heating of hot water does not adversely affect the temperature of the coolant. For example, for heating a dacha with an area of ​​​​70-80 square meters. m will be enough to buy a boiler with a thermal power of 8-12 kW. Big house or a cottage with an area of ​​​​more than 200 sq. m is able to heat the device with a power range of 22-35 kW. Experts do not advise chasing too productive models; frequent turning on and off the burner will strain the residents.
4. Safety. Gas equipment refers to devices dangerous to human life. Therefore, it is necessary to study the security systems available in the boiler. The standard set of a modern gas boiler includes gas control, protection against overheating and pump blocking, self-diagnosis, and a safety valve.

The specialist in their repair tells in detail about the criteria for choosing a gas boiler in this video:

Gas heating is often used to provide a comfortable microclimate in modern ones.

This option in Russia is chosen by more than half of all buyers.

Making the right choice of a gas boiler for a private house is not so difficult, it is enough to understand the main features of the device.

In fact, any gas boiler becomes the main node in the heating system.

Without it, the coolant does not heat up.

And it is not able to circulate along the circuit constituting.

Gas devices today are produced in a wide range.

There are the following signs by which devices are divided into several groups:

• A number of design features
• How does the coolant move?
• Where is the device mounted?
• How much power do they have

These features are interdependent. Therefore, each of the points can be considered separately.

Power rating

Domestic includes any boiler used in the system country house. Power is usually in the range of 5-500 kW. Most models need 10-35 kW.

How to find out how much power a particular buyer needs? There is a concept of an average standard that is suitable for most situations. About 1 kW of device power is spent on heating 10 square meters area in standard rooms.

Power increases with ceiling heights of 3 meters or more. Therefore, devices are purchased with a margin.

But in practice, the figures often become smaller. It's connected with technical features that the device has. The distribution of power in this case is sequential.

The design of the house, climatic features are factors that are given no less attention. More power is required if the device is operated in northern regions.

Or in houses where the walls are very thin. The choice of a gas boiler for a private house of 70 sq.m. should not cause much trouble.

What about the location

On this basis, gas boilers are:

• wall mounted
• floor standing

Floor - those that are mounted only on the floor. It is advisable to place them in the vestibule, or in another separate room.

Such devices have whole line advantages:

• Wide model range.
• Long battery life. Typically, the device can work smoothly for 2 days - 1 month.
• Simple service.
• Versatility. For work, you can use any available types of fuel.
• Profitability.
• Performance, high power at the level of 0.5 mW.

efficiency modern devices goes up to 90 percent. Non-volatile is most of fixtures. This means that they work without .

There are systems with a long burning function. They have only two main elements: equipment for automating fuel supply plus the boiler itself.

But floor models are not without their drawbacks:

• They have large dimensions.
• Requires a separate place for installation.
• They do not work without a chimney that performs its functions stably.

Floor standing boilers require solid foundation made of iron or. But this is the best solution for those who do not need a boiler in residential areas.

A little about wall-mounted boilers

It is they who make up about half of all gas devices that actually work in homes. The classic option is when the device is placed on the wall, in the hallway or in the kitchen.

Among the advantages:

• The system does not have a chimney in its classical sense. Mount a compact, coaxial version of this device.
• The work is absolutely silent.
• High rate of efficiency.
• Simple operation. It will not be difficult to choose the required temperature mode.
• Almost complete automation.
• Attractive appearance.
• Light weight with size.

But it was not without its shortcomings.

• The boiler cannot immediately work both for space heating and for bringing water to the desired temperature.
• There are some restrictions on the maximum power and area of ​​​​rooms that are heated in this way.
• Devices impose stringent requirements on the quality of heat transfer fluids.
• Most models are volatile

Wall-mounted devices will be a good solution in small houses. They do not require much space for installation. Combustion products will be discharged through the coaxial chimney. runs straight into the wall.

How can coolant move

The type of heating circuit is of great importance for those who choose the right boiler. To be more precise - important role plays how the circulation of the coolant is organized. Water usually moves in one of two ways:

• Forced amplification of the process. What are circulation pumps used for? In most boilers, such pumps are already built inside. If they are not there, then the structures are easy to mount separately - in the lower part of the heating circuit.
• Sometimes heating is responsible for the circulation movement. The liquid moves upward along the circuit when it is heated to a certain temperature. Its place is taken by another liquid that has not had time to warm up. The cycles repeat indefinitely until the device turns off.

Design features

First, the water is in the heating circuit.

And then goes to the heat exchanger.

The latter is heated by the combustion of gas.

With the help of burners, the gas begins to compress.

In total, each of the designs provides for the presence of two burners - one ignition, the other - the main one.

The main one is needed to maintain a normal operating mode.

The second helps the main ignite after the device stops working, and turns on the "standby" mode.

Boilers are “ignited” in different ways - automatically, manually. Or using electricity. There is also a piezo option.

Gas boilers can be:

• With two circuits.
• Single-circuit.

The second type of models is supplied with only one circuit along which the coolant moves. It is in it that the heating takes place.

In the second type of circuit two - the second for water, used for domestic purposes. It is suitable for those who want to make a choice of a gas boiler for a private house of 200 sq.m.

It is the second circuit that is called the DHW circuit. Inside the structure there is a heat exchanger, one or two.

Boilers are divided into groups and depending on what materials heat exchangers are made of:

• With copper base.
• From stainless steel.
• Silumin.
• Of steel.
• Cast iron base.

Cast iron and steel are the most widely used. The first material retains heat for a long time, but remains fragile. Steel is short-lived, although it also conducts heat well. Stainless steel, based on silumin, also have high characteristics. But they are quite expensive.

In condensing type boilers, silumin heat exchangers are more often preferred. They differ from others in that the coolant moves through them at a lower temperature.

The difference, compared with conventional models, reaches 10-20 degrees. Gas combustion products are used to heat water. Due to this mode of operation, less condensate appears on the heat exchanger.

Eat classic varieties, where moisture condenses due to the difference that appears between the outgoing and incoming liquid temperatures. Such models are best used in conjunction with warm, radiators with a large number of sections.

Then the low temperature of the coolant ceases to be a serious problem. Compensation devices have a high efficiency of up to 90-95 percent.

In many systems there are elements responsible for the safety of operation, automation. Such elements usually consist of:

• Chimney draft sensors.
• Working with fans.
• Valve mechanisms for relief, protection from dangers.
• Control units with indication of the corresponding operating mode. Use electricity, or work on the principle of automation.

Most of the space inside the structure is given to gas fittings. The same applies to the circulation pump, exhaust manifold with fan, burners with heat exchanger. Thanks to modern technologies it is easy to choose one that fully meets the requirements of a particular buyer.

There is also a division into categories depending on where the gas burns. They are supplied with closed or open chambers. In closed chambers, tightness is ensured, they are isolated from the external volume in all rooms. Only through the coaxial chimney a sufficient amount of air enters.

Ignition method, burner and power

In the main highways of our country, gas pressure is far from ideal.

This is especially true in winter. Sometimes it drops to a minimum of 13 mbar.

Which leads to a decrease in the flame inside.

Then, for the same reason, burnout occurs.

Although the cost increases markedly, and the work is not complete without extraneous noise.

Gas boilers are produced not only by domestic, but also by foreign manufacturers. Such models are designed for operation at a stable nominal pressure of 18-20 mbar.

When using imported equipment, the likelihood increases that buyers will be left without heat in severe frosts.

As for the type of ignition, everything here depends on the desire of the owner to save on electrical energy. One of the most convenient options is the so-called piezoelectric element. This means that a small igniter is permanently installed in the burner.

heating calculations

They do such calculations when they are only designing the house itself. Among the factors that have a serious influence on the choice of a heating system are walls with their thickness, roofs and roofs with structural features, and the quality of thermal insulation. These indicators determine what will be:

• Plumbing and household appliances with their total number.
• That, using which scheme the coolant moves.
• What type of wiring is.
• Highway slopes.
• The number of radiators at the pipes.
• The boiler itself.

The selection rules remain approximately the same for all boilers, not just gas ones. Electric models are considered a more profitable purchase. In this case, you do not need to constantly press the button to turn on the device.

The main thing is to buy a voltage stabilizer so as not to suffer from its surges. It is best to purchase devices with all the necessary sensors included.

Among the main functions:

• Traction control sensor.
• To block the gas supply if the flame goes out.
• Blockers that stop work when the gas and water supply is turned off, power surges.
• A blocking thermostat that prevents gas supply when water reaches certain temperatures.

The right cauldron

Savings are unacceptable when choosing the automatic part of the burners. In case of any interruptions in gas, the valves should work perfectly. Otherwise, serious problems will arise in the future. 500 euros can reach annual losses for those who buy cheap boilers with low efficiency.

It is necessary to take a closer look at the materials from which the boilers are made. Cast iron and copper are more durable than thin sheet steel.

Adjustment equipment is one of the most important aspects that cannot be skimped on. It depends on them how efficiently the thermostat works.

Installing gas boilers is not as easy as it seems to many. All requirements must be met. And installation is not possible without obtaining special permission. The best thing to do is to contact the experts who provide the relevant services.

Possible leakage and open flame are the main reasons why buyers consider it dangerous to purchase gas boilers. Such warnings are only partly justified.

The costs are paid off by saving and supplying heat exactly at those moments when it is really needed. The main thing is to carefully monitor the pressure indicators. The advantages of the devices have been appreciated by many buyers.

How to choose a gas boiler, you can watch the video:

It is difficult to choose gas boilers - they are usually sold already with apartments or houses, so people simply do not know what to look for. But what if you urgently need to purchase good equipment, and time to delve into everything design features No? In fact, a lot of knowledge right choice and don't need to. And the availability of a ready-made rating of gas boilers for 2019 makes it easier for the buyer.

What to look for when choosing a gas boiler

When choosing a gas boiler, you need to rely on the reputation of the company and its breakdown statistics. But there are some criteria, without which it is simply impossible to find a good device. Let's try to figure out what you need to remember before buying gas equipment:

• Boilers are divided according to the installation method into wall and floor, so analyze where you have more space;
• The type of boiler - convection and condensing - must be selected depending on the desired price;
• The number of circuits - there are double-circuit and single-circuit boilers - affects whether the boiler can heat water;
• The greater the heated power, the better the device will work;
• The type of combustion chamber - closed or open - indicates whether a person can see how the boiler works;
• Exist different sizes boilers, so it is important to consider the area of ​​\u200b\u200bthe room where it will be installed;
• High-level security is literally vital, because gas equipment may explode.

Choosing the best gas boiler for an apartment is not an easy task. It is even more difficult to obtain official approvals from all relevant authorities for the installation of such heating device in a multi-storey building. However, there is a chance if all the rules of the procedure provided for by law are observed.

The main criterion for choosing any gas boiler is correct calculation the required power. This indicator is calculated depending on the area of ​​​​the apartment, as well as on the presence of additional power consumers, for example, hot water or underfloor heating systems. Also, productivity will have to be increased if your apartment has old ventilated windows and doors, and the house is poorly insulated.
