How to choose a wall-mounted boiler
Every day, wall-hung boilers are becoming increasingly popular. And it is quite obvious, because they have a great advantage over the floor boilers: compact size, complete with pump and expansion vessel and safety valve. They are only suitable for individual heating, and in combination with providing hot water in your apartment or house.
Instruction how to choose a wall-mounted boiler
You need to decide for what purposes it is going to install wall-mounted gas boiler: to provide heating or together with this you need a supply of hot water. In the first case, if you have a central water supply, you need a single-loop boiler, and in the second - two-circuit.
Define the second important characteristic of the boiler: open or closed combustion chamber. First - Chimney (natural draft) requires the obligatory presence in the house chimney. In his absence, used turbo boilers (with closed combustion chamber). The kit includes a fan of the boiler and a special air supply system and smoke. Its advantage is that it does not burn the oxygen in the room, and the air to support combustion enters the system directly from outside directly into the boiler.
Next, determine your required boiler output. Calculate it can be approximated as follows: 1kW at 10 square meters heated area.
If you install a bypass boiler, calculate its performance. To do this, you must consider how much hot water outlets you plan to install in the house. For one - pot required performance ≈ 6 liters per minute for two or more - 12 liters per minute.
Check the identification characteristics of boilers offered to you. Pay attention to the amount of gas consumed.
Define the required parameters for the automation of your boiler. Modern automatic heating gas boilers are very convenient, because they control the pressure and heat of coolant, the presence of the flame and draft in the chimney, in the event of a threat or missing some factor, automatic shut off mechanism and the boiler will block the flow of gas.
