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 limiting pressure. In order to understand this issue in more detail, you need to familiarize yourself with the device of the tank.
Expansion tank arrangement
Standard type expansion tank includes safety valve, membrane, and safety valve. The cold water outlet is usually located at the top of the structure.
