What to look for when choosing?
To choose the right gas boiler, you need to pay attention to the following:
- Material and design of the heat exchanger. There are heat exchangers made of cast iron, stainless steel and copper. The most durable is the cast iron version. But it has a heavy weight, and if used improperly, it can burst. Therefore, a copper heat exchanger with a bithermal coil is considered to be quite good.
- type of instalation. Boilers are floor and wall. Mounted are inferior to the second samples in terms of power. But still the choice depends on the preferences of the buyer.
- Number of circuits. The manufacturer produces single-circuit and double-circuit gas boilers.The first type acts as independent equipment, designed to connect heating. Double-circuit models are able to heat water for domestic needs and heating, they are used in private homes.
- Type of combustion chamber. There are two types - open and closed. The boiler with an open chamber is suitable for installation outside residential premises: in the basement or in a special annex. Closed - in apartments where it is not possible to equip a chimney.
