摘要

System for recovering heat from waste water comprises: (1) collecting waste water in an automatically cleaned tank (1); (2) feeding it over evaporator plates (4) connected to a supply of gaseous coolant (5); and (3) feeding the heated coolant into a compressor and releasing the generated energy to heat the domestic water supply via a heat exchanger. A control system (11) controls all operations.
