Review of the best according to the editorial board. On the selection criteria. This material is subjective and does not constitute advertising and does not serve as a purchase guide. Before buying, you need to consult with a specialist.

The most profitable and comfortable way to heat a private house in Russia is gas. Modern gas boilers allow homeowners to enjoy the warmth and comfort carefree throughout the entire heating season. In addition, double-circuit models also provide the household with hot water. Many users prefer floor-standing gas boilers. Our experts will help you choose the most suitable model for your home.

Criteria for choosing a gas boiler

1. One of the most important characteristics of a gas boiler is its heat output. This value shows the maximum amount of heat that the device can produce when burning blue fuel. Power is selected taking into account the heated area. It is generally accepted that for heating 10 sq. m requires 1 kW of thermal energy. However, such a ratio is ideal, and since gas boilers have an efficiency of 90-95%, a more powerful unit should be chosen (by about 10-15% of the calculated value).
2. Floor-standing gas boilers can be single and double-circuit. If the house has a source of hot water or it is not required every day, then single-circuit models should be preferred. Otherwise, it is more profitable to take a double-circuit device.
3. Many modern models must be connected not only to the gas main, but also to a single-phase electrical network. In those settlements where power outages often occur, it is better to install non-volatile models. The only inconvenience will be manual ignition of the burner, and the connection is carried out to an open-type heating system with good natural circulation of the coolant.
4. The main component of the boiler, which experiences extreme loads during operation, is the heat exchanger. The most durable are cast iron products. Steel analogs are susceptible to corrosion, deformation and cracking of the walls often occur. But boilers with steel heat exchangers attract buyers with their affordability.
5. Some homeowners are interested in multipurpose gas boilers that are capable of operating on both natural and liquefied blue fuel.
6. When buying a gas boiler, you should pay attention to the gas consumption. Low-power models do not always win in efficiency over more productive competitors. It should also be noted that the consumption of natural gas is indicated in cubic meters per hour, and liquefied gas – in kilograms per hour.
7. According to the control method, there are gas boilers with a mechanical or electronic unit. The mechanics are cheaper and easier to maintain, and the presence of automation allows you to set the desired air temperature in the rooms and no longer interfere with the operation of the boiler.

We have selected 11 of the best floor-standing gas boilers in our ranking. All of them have been successfully tested in the homes of Russian citizens. When allocating seats, the opinion of the expert community and user reviews were taken into account.
