How to select the capacity of the expansion tank?
Most often, a tank is selected that constitutes 8-10% of the volume of the entire installation. Enough for small systems CO expansion tank 10l, to medium CO expansion tank 20l or 30 years old. In larger installations, it is worth consulting the selection with a specialist.
Can the expansion tank be used in a hot water installation?
