Many heating systems involve the use of expansion tanks. These elements are necessary in order for excess water to flow there. The calculation of the expansion tank of the heating system is carried out taking into account the power of the boiler, as well as the volume of the coolant.
The main parameters of the modifications include the size of the nozzles, as well as the ultimate pressure. In order to more thoroughly understand this issue, you need to familiarize yourself with the tank device.
The device of expansion tanks
A standard expansion tank includes a safety valve, a diaphragm, and a safety valve. The cold water outlet is usually located at the top of the structure. Many models use an air chamber to stabilize the pressure in the housing. Connection to the heating system is through the inlet pipe. The safety valve is generally used with a restrictor.
What kinds are there?
To date, cameras are open and closed. There are also devices with protective fittings. Open type modifications are made with one or more membranes. Their airbags are quite large. Many modifications are able to boast a high heat transfer parameter. Closed type devices are available in different sizes. Double fuse models are rare on the market.
For gas boilers, closed-type modifications are great. Circulation pumps may be used at 5 kW. Cranes in devices are used coupling type. Tanks with a choke mechanism are more suitable for powerful electric boilers. Install devices behind the mixers. Retrofit modifications are rare. There is an average expansion tank for the heating system 2300 rubles.
