<p>The heat pump system has a coaxial heat exchanger (2) that is connected with a wastewater pipe (1) directly or by a wastewater buffer container and a wastewater pump (12) that the wastewater is supplied continuously to the coaxial heat exchanger by the wastewater pump and from there is conducted in the wastewater pipe. A heat pump circuit is provided, which has a compressor (4), a capacitor (5), an expansion valve (6) and the coaxial heat exchanger serving as an evaporator. The capacitor is connected with a hot water circuit for using the gained heat by the heat flow line (51).</p> |
