The best gas boilers for heating a private house, cottage, bath and apartment

From this article you will learn which gas boilers are the best in their classes. Leaders will be represented in the material, both among the two-circuit ones and among single-circuit devices, as well as the optimal versions of boilers for different rooms - houses, apartments, cottages and baths.

Which gas boiler is better to buy?

The modern market of heating boilers offers consumers devices in the most carved price categories - from cheap Chinese equipment of doubtful quality, to expensive branded boilers with turbocharged combustion chambers and other twists.

Among the manufacturers it makes sense to mention the following companies: Baxi, Protherm, Buderus, Vaillant, Bosch, Viessmann and Ferroli. These are serious companies that are present on the market for a long time, the quality of their products is checked by hundreds of thousands of customers.

The best producer of gas boilers from Russia is Irbis, whose products can be considered as a budget option. Domestic boilers, although losing to foreign devices, compete in terms of TTX and ease of use, but their direct functions are performed with dignity.

Rating of the best gas boilers

There are several types of gas boilers, and therefore, choosing a model for the house you need to know exactly what you need. In short we will go through the classification of each type of heating equipment:

Single-circuit and two-circuit

Single-circuit gas boilers in basic configuration are used exclusively for heating the room, while two-circuit, in addition to the heating of the dwelling, is also responsible for the supply of hot water.

It is worth noting that, if desired, a boiler can be purchased additionally to a single-circuit boiler, and then it will be able to perform all the functions of a two-circuit boiler.

In terms of design features, these species have significant differences: two-circuit boilers are much more compact, which makes them ideal for rooms with limited free space, but they are also more demanding in terms of operating conditions. The dual-circuit boiler performs the heating of the running water, and in order for the DHW system to automatically switch on, the flow of the incoming liquid must have a high pressure, which means that it is practically impossible to save hot water.

Also two-circuit boilers are not the best solution for large-sized rooms, where the water intake devices - cranes, shower, etc., are far from the boiler itself. This is due to the fact that the heating system, based on a two-circuit, can not be equipped with an additional circulation pump.

Single-circuit boilers also have their own peculiarities, among which there are large dimensions and labor-intensive installation. When using a boiler system based on single-circuit boilers can be supplemented by circulating pumps to supply hot water to several points of water intake, but the efficiency of such a system is limited by the volume of the boiler.
It is also worth noting that the total cost of a system consisting of a single-circuit and a boiler is higher than the cost of a dual-circuit boiler.

Floor and wall

Here everything is simple - floor boilers are installed exclusively on the floor - they have much larger dimensions and power than wall analogues, which makes sense to use only in case of limited free space.

Typically, the power of most wall-mounted boilers is limited to 35 kW, as they have a copper heat exchanger that is unable to withstand high temperatures.

Floor standing boilers are the best option for heating rooms ranging from 150 to 600 sq.m. Depending on the equipment, floor boilers can have either an atmospheric or turbo burner. A distinctive feature of atmospheric burners is endurance, noiselessness and high price, whereas boilers with turbo burners have an order of magnitude greater efficiency, but also cost significantly more.

The best gas floor heating boilers

Having studied the classification of modern gas boilers, we turn to the rating. To this end, we analyzed the numerous reviews of the owners of the most different boilers and identified the best models in each class of heating equipment.

Single-circuit gas heating boilers

Let's start with single-circuit units, as they are the most popular types of gas boilers.
