How to choose the volume of tank
In order to ensure the hot water can be used at any time for 24 hours, the energy center uses a insulated presure storage tank. The volume of the water tank can be calculated according to heat pump /solar collector’s heating capacity and the number of hot water users, which is normally calculated as 50L/per person.
For example, a family have 4 persons and how many Liters of tank shall it use for hot water shower? 50L *4=200L
