What should I pay attention to when choosing?

To choose the right gas boiler, you need to pay attention to the following::

  • The 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. So it is considered a copper heat exchanger with bittermann coil.
  • Installation type. Boilers can be floor-standing or wall-mounted. Mounted ones are inferior to the second samples in terms of power. But still, the choice depends on the preferences of the buyer.
  • Number of polygons. The manufacturer produces single-circuit and double-circuit gas boilers. The first type acts as an independent equipment, designed for connecting heating. Dual-circuit models are capable of heating water for domestic needs and heating, and are used in private homes.
  • View of the 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 extension. Closed — in apartments where it is not possible to equip a chimney.
