Abstract

A water saving system (10) comprises a pump (12) operatively connected to a water line (18) leading to a hot water outlet; means for detecting a demand of hot water (116) at said hot water outlet (16); means for triggering the operation of said pump (12) in response to the detection of said hot water demand; whereby said pump (12) draws water in said water line (18) towards a cold water storage tank (120) such that the water line is purged; means for detecting the arrival of air (114) at a point of said water line; means for switching off said pump in response to said arrival; said pump or an additional pump being operatively connected to said water line leading to a hot water outlet (16); and means for switching on said pump or an additional pump following said arrival in order to refill said water line with hot water,- whereby hot water is delivered at said hot water outlet (16).
