<P>PROBLEM TO BE SOLVED: To provide a hot water supply system easily and surely preventing blockage of a water flow channel by suppressing generation of scale in the water flow channel of a gas cooler. <P>SOLUTION: This hot water supply system (1, 50, 58, 60) performing a boiling-up operation to boil up the water of low temperature flowing in a water circulation passage (9) from a hot water storage tank (6) of a tank unit (8) to the water of high temperature by a refrigerant of high temperature flowing in a refrigerant circulation passage (5) of a heat pump unit (4), has: the gas cooler (2) having a refrigerant flow channel (2a) in which the refrigerant of high temperature flows by the boiling-up operation, and the water flow channel (2b) in which the water of low temperature flows; and a scale generation suppressing means for suppressing the generation of scale in the water flow channel, by distributing the water of low temperature to the water flow channel after the termination of the boiling-up operation. <P>COPYRIGHT: (C)2011,JPO&INPIT |
