Gas boilers are designed not only for heating the house, but also for organizing a hot water supply system. There are several varieties of them, so before buying it is necessary to determine which design will be the most suitable.
How to choose a gas heating boiler in 2022?
All boilers on sale can be divided into two large groups: single-circuit and double-circuit. The first variety is intended solely for creating a comfortable temperature in the room, while the second is also used for supplying hot water. Double-circuit boilers are more compact in size, however, increased requirements are imposed on the conditions of use. In particular, in order to automatically shut off the hot water supply, the incoming flow must have a fairly high pressure. Because of this, it is almost impossible to save hot water.
For large rooms, double-circuit boilers will not be the most suitable option, especially if the water intake equipment is located quite far from the boiler. Single-circuit products are large and difficult to install.
Also, all boilers on the market can be divided according to the installation method — floor or wall. Floor-mounted ones are more powerful, differ in significant dimensions, they can be used to heat a room with an area of u200bu200babout 600 square meters. m. In our ranking of the top 10 best gas boilers, all types of such heating equipment are presented. When compiling it, we take into account the price-quality ratio of the model, the opinions and reviews of customers, and many other factors. We hope that our rating will help you decide on the most suitable model.
