Functional Description

Heat Pump

The outside air (2) is aspirated through the evaporator (4) (air-to-refrigerant heat exchanger) of the heat pump by means of the fan (3). The heat pump draws heat energy from the outside air in the evaporator and delivers this directly to the storage water (6) in the condenser (5) (refrigerant-to-water heat exchanger) of the heat pump.

Heat Storage Tank

The storage tank (6) is heated via the heat pump and, where applicable, a solar thermal system (11) or water-conducting fire place. If the energy recovered from the heat pump and solar thermal system is not sufficient, the electric heating element (10) is switched on in a controlled manner. The energy recovered from the heat pump is supplied directly to the storage water (6) in the condenser (5) (refrigerant-to-water heat exchanger) of the heat pump. The energy recovered from the solar thermal system is supplied via the heat exchanger (9). Via the domestic water heat exchanger (8) energy is removed and supplied to the tap connections in the building. The static heating surfaces are connected directly at the storage tank.
