The pump kit is required when the available heat pump
pressure is too low to cover the system pressure drop. The
water pump in the heat pump will then be used to irrigate the
comfort module buffer tank and the additional comfort module
pump is used to distribute the heat from the comfort module
buffer tank to the terminal units.
