built inside. When install the unit, installers should connect the heat pump
with other parts including the buffer tank (for space heating/cooling), storage
water tank (for domestic hot water) and water pumps (for space
heating/cooling water circulation and domestic hot water). External fittings
are also needed including a safety valve, a water charge valve, hot water
valves (three-way valve). Temperature sensor should be added in the
storage water tank. An additional electric heater can be installed in the DHW
tank or the buffer tank which can get the control signal from the heat pump.
