Since gas in Russia costs an order of magnitude lower than electricity, many owners of private houses are turning to the installation of gas boilers. However, economic parameters are far from the only advantage of this type of units over the others - they include high thermal power, optimal efficiency, minimal emissions, as well as the possibility of heating large areas (on average from 150 to 300 square meters).
Of course, like any other technique, gas boilers have disadvantages. These include strict coordination of the installation with the federal service of Gaztekhnadzor, equipping the house with a chimney to remove (a small amount) of combustion products, as well as the introduction of automation to detect gas leaks.
In our rating you will find 15 of the best and highest quality gas boilers, the purchase of which will provide you with heat and hot water for many years. Before that, we advise you to study some of the nuances of choosing a gas boiler for a house or apartment.
The right choice - double-circuit or single-circuit?
As you know, according to the number of circuits, gas boilers are usually divided into single-circuit and double-circuit ones. Which one is better? The correct choice depends on the main purpose of the device.
Single-circuit ones are designed exclusively for the operation of the main coolant (radiators, pipes, etc.), that is, they are bought to provide heating. Most often, such devices are placed in cottages and in places where there is no water supply.In this case, a boiler is purchased for a single-circuit boiler for heating water in an autonomous water supply system.
Double-circuit boilers are 2 in 1 devices. They can both heat the house and provide hot water. The coolant and the boiler in such a device are assembled into one unit. If hot water is not consumed, the coolant circulates in the heating circuit. As soon as the user opens the hot water tap, the system switches the valves so that the coolant is directed to the second circuit. This is the most popular type of gas boilers that are installed in most apartments and private houses.
Heated power
The more powerful the boiler, the higher its cost. In order not to overpay extra money and eliminate additional costs in the future (the more powerful the boiler, the more resources it consumes), it is important to calculate what kind of gas boiler you need. An approximate calculation is as follows: per 10 sq. m. of a well-insulated room (ceiling height up to 3 m) should account for 1 kW of boiler heat output. For a poorly insulated room, another 30–50% is added to the heat output.
For a country house of 50 sq. m. enough to purchase a gas boiler with a capacity of 7 - 12 kW. But for a house of 200 sq. m. You will already need a more powerful device: 23 - 25 kW. Most modern double-circuit gas boilers are produced with a thermal power of 24 kW.
When choosing the power of the boiler, there is another important detail. If you take a device that is too powerful for a small room (for example, a 24 kW boiler for a one-room apartment of 40 sq. M.), The boiler will quickly heat up the coolant and turn off. As soon as the water cools down, the boiler will start again.Constant switching on and off will happen very often, which will lead to accelerated wear and increased gas costs. In turn, a boiler with a lower power will ensure smooth combustion, and switching on and off will occur much less frequently.
Which company should be preferred?
The highest quality and most reliable gas boilers are manufactured by Italian, German and South Korean companies. Even taking into account the fact that many companies locate their production facilities in China, purchasing a popular brand gas boiler is better than buying a little-known device.
To make your choice easier, here is a list of the best gas boiler manufacturers:
- Navien (South Korea);
- Bosch (Germany);
- Ariston (Italy);
- Baxi (Italy);
- Buderus (Germany);
- Vaillant (Germany);
- Protherm (Slovakia);
- Viessmann (Germany);
- Kiturami (South Korea).
Voltage stabilizer for a gas boiler - is it necessary or not?
After buying a gas boiler, it is advisable to install a voltage stabilizer. Especially if your network suffers from frequent voltage drops. The fact is that in the event of a boiler failure due to a power surge, it will not be possible to exchange the device under warranty. The requirement for network quality is specified in each warranty agreement. Therefore, it is better to spend extra 3-5 thousand rubles for a device with a power of up to 1 kW (and you don’t need a powerful stabilizer for the boiler) than to lose tens of thousands of rubles as a result.
The best inexpensive wall-mounted gas boilers
The main advantages of wall-mounted gas boilers are low price and compactness in placement. They are more suitable for rooms with limited space. For example, for an apartment. The disadvantages of wall-mounted models are low power and shorter service life, unlike floor-standing devices.

1 Rinnai BR-R24
Country: Japan
Average price: RUB 81,500
Rating (2022): 4.9
It is not for nothing that the Japanese are known as techno-freaks - they even managed to fill the Rinnai BR-R24 gas boiler with the most modern electronics. What makes it unique is, first of all, the algorithm for automatically maintaining the optimal ratio of the gas-air mixture in the working chamber. The process is controlled by the "brain" with touch sensors. This achieves an unprecedentedly wide power output range from 17 to 100% and, as a result, a reduction in gas consumption and an increase in the service life of the primary heat exchanger.
You can control the model from the Standard modification remote control (supplied in the basic kit), Deluxe or Wi-Fi.With it, you can program an individual mode of heating and hot water supply, which will be maintained automatically depending on the indicators of sensors outside and inside the building. Changes in the settings are duplicated by the voice navigator. 2 microprocessors are responsible for safety at once, controlling and correcting each other's work. This is not a boiler, but a space rocket, not otherwise!
