Abstract

A system for saving cold water retained in a hot water line is provided, comprising: a) a reservoir for collecting cold water, with means for indicating the level of water in said reservoir; b) at least one electrical valve that allows filling or emptying of said reservoir according to an open or closed state of the valve; c) a sub-pressure generating mechanism connected between a consumer outlet line and a water faucet connected to said hot water line, said mechanism including an inlet for bypassing the flow of said cold water to said reservoir, upon opening said water faucet, and for mixing said cold water with water from said hot water line, whenever the temperature of the hot water is above a predetermined value or whenever said reservoir is full; and d) an electronic unit for controlling said electrical valve according to water temperature, water pressure and water level.
