In a heating system, which operates by air circulation, a partial flow 16 of spent air is supplied to a heat exchanger 4 for heat exchange with intake air 12, which comes from outside, and with a return flow 14 of circulation air from the heating system. After passing through the heat exchanger 4, the mixture of intake air and return air is conducted, as the heat-transmitting medium, to the evaporator of the circulation heat pump 5. The quantity of air which circulates through the heat pump is kept greater than the partial air flow which is blown out from the heating system via the heat exchanger. In the event of an increased energy requirement, the partial flow is blown out by means of a suction fan 7 and can moreover be mixed with flue gases from a heating boiler 2 which preferably conducts water. <IMAGE> |
