The key element of the heating system of a private house is the boiler. In many respects, the air temperature in the room, the general costs associated with paying for heating, depend on how high the quality of the device itself, on the efficiency of its work. Wall-mounted boilers have a major advantage over other similar heating equipment: they take up a minimum amount of free space. There are a large number of different models of wall-mounted units on the market, which differ from each other in a number of parameters:
- Number of circuits: single circuits are designed exclusively for heating, double circuits will also provide the house with hot water;
- The type of combustion chamber is open (needs a natural chimney system) and closed (from it the combustion products are forcibly sent to the coaxial chimney, which is the safest);
- The presence of electrical devices;
- Type of burner: atmospheric or modulating, the power of which the boiler regulates independently.
When developing this rating of the best wall-mounted boilers of the year, we took into account all these features, we also took into account the opinion of customers, the country where the equipment was created and produced. We tried to compile the most understandable and informative rating, so that after studying it, it would be easy and simple for the reader to choose the most suitable heating boiler for his home.
