Tool Reviews

A gas boiler is a demanded equipment for apartments and private houses. The device generates thermal energy, which is used for space heating and heating tap water. The gas boiler is easy to operate, safe and economical.

How to choose a gas boiler

When buying equipment for heating, it is recommended to take into account such characteristics as the type of operation, power, type of traction, assembly method, type of heat exchanger.

• Type of operation – buyers are offered single- and double-circuit models. A single-circuit gas boiler only heats the room, while the water heating function is possible when installing additional equipment. The double-circuit unit is equipped with a second heat exchanger, due to which tap water is heated.
• Power – when considering this parameter of a gas boiler, the area of ​​\u200b\u200bthe room that needs heating is taken into account. The optimal indicator is best agreed with experienced designers.
• Type of draft – gas boilers come with natural and forced draft. The latter are equipped with a fan that draws air from the room and eliminates combustion products. To install such a boiler, it is necessary to install a coaxial chimney designed to remove carbon monoxide. In a natural draft unit, air enters from the room, and combustion waste exits through the chimney. For this reason, natural draft models are only installed in homes that have standard chimneys.
• Method of assembly and installation – gas boilers are divided into floor and wall. Floor models are characterized by large dimensions, therefore, a separate room is required for the installation of such equipment. The most powerful floor heaters are those that have a ventilation burner. If the equipment is equipped with an atmospheric burner, then its power will not exceed 80 kW. The disadvantages of the outdoor device include the complexity of installation. Wall-mounted equipment is more compact, but less powerful.
• Type of heat exchanger – if there is any doubt about the quality of tap water, it is better to choose a gas heater with a separate heat exchanger. In such equipment, water is heated outside the radiators, due to which they are protected from lime, rust and other impurities deposited on the walls of water pipes. If high quality water is supplied to the house, then you can safely purchase a device with a bithermic heat exchanger.

Minor Criteria

• design and color scheme;
• the country of manufacture;
• the presence of additional functions (frost protection, underfloor heating, and so on).
