The system comprises a refrigerating circuit, which acts as a heat pump and includes an electric compressor (48), a condenser, a throttling element (58), and an evaporator, and a line (24, 30) for supplying liquid from supply to a user take off. The condenser of the refrigerating circuit is constituted by one section of a heat exchanger, the other section of which is traversed by the supply line (24, 30) for the liquid at the desired temperature for use. The system further includes a waste line (36) for hot used liquid, which passes in succession through one section of a heat exchanger (14) the other section of which is traversed by a feedline between a supply and the exchanger of which the condenser forms part, and one section of a heat exchanger (44) the other section of which is the evaporator of the refrigerating circuit. The whole system is contained in a parallelepiped casing (86) subdivided internally into side-by-side compartments (88, 90) hot water insulated storage chamber (26) being provided in compartment (90). <IMAGE> |
