Guidance to select an expansion membrane tank
If to connect a boiler to the eating system with a volume more 70 liters, it is necessary to install an additional
expansion membrane tank, by connecting it to the return line ("by-pass") really close to the boiler.
In the tables presented below, you can find water volume necessary for fulfilling elements of the heating system.
Volume of the boiler by itself is 2 liters. This data allows to make an approximate calculation of the water quantity in
the heating system to which boiler will be connected.
