Abstract (en)
In proximity to each tap, or element to which the economizer wants to be applied, a circuit (10) is sandwiched into its water intakes, presenting: a cold water inlet (2) of the system connected with a cold water outlet (4) to the tap through a cold water electrovalve (9); a hot water Inlet (1) coming from the boiler or similar, connected with a hot water outlet (3) to the tap through a flowrate detector (6), a temperature detector (7), and a hot water electrovalve (8) that has an outlet to the return circuit (5) connected with a return water pipeline joined in proximity to the boiler or similar to its cold water intake. In proximity to the connection between these last intake and pipeline are respective non-return valves, said pipeline being further provided with an impulse pump.
