Hot water system by solar energy with waste energy recovery.

摘要

Hot water system by solar energy with waste energy recovery.; Hot water system, solar energy comprising at least:; a plurality of tanks (1, 2, 3) arranged in series, usually two or three; so that hot water (11) exiting the plurality of solar collectors (4) passes through the first tank (1), and then the second (2) and third (3), the last tank (3 ) is maintained at a lower temperature than the first (1) and second (2) deposits, comprising said last tank (3) also a heat exchanger (71) by passing the greywater (10) giving up its heat .
