<p>The hydraulic circuit has a two-section drain system recovering energy in a house, commercial premises etc. Two separate drain pipes (6,7) are installed, the first one (6) handling only warm drain water with a relatively small degree of pollution, and the second one (7) the remaining water and particularly sewage. After extracting the heat from the first pipe by an integrated heat pump (11), the two pipes are joined in front of the connecting point (8) to the main drainage system (9) etc. The water from the first pipe can be directed into a heat-insulated collector vessel (10) with an integral heat pump.</p> |
