<p><P>PROBLEM TO BE SOLVED: To prevent water which becomes cold water within a hot water supply pipe from coming out from a hot water supply tap when it is opened, in a hot water storage type hot water supply system. <P>SOLUTION: The hot water storage type hot water supply system 1 is provided with a hot water supply tank 2, a heating source 3 for heating water in the hot water storage tank 2, and the hot water supply pipe 6 for interconnecting the hot water storage tank 2 and the hot water supply tap 60. The hot water supply pipe 6 is constituted by connecting a first hot water supply pipe 6a connected to the hot water storage tank 2 with a second hot water supply pipe 6b connected to the hot water supply tap 60 via a hot water supply mixing valve 6c. One ends of first circulating piping 7a and second circulating piping 7b are connected to the hot water storage tank 2, respectively and the other ends are connected to the second hot water supply pipe 6b, respectively. A circulating pump 7c is provided in a circulation passage 7 constituted by the first circulating piping 7a, the second hot water supply pipe 6b, the second circulating piping 7b and the hot water storage tank 2. By driving the circulating pump 7c, water becoming cold in the circulation passage 7 is heated by supply of water at relatively high temperature inside the hot water storage tank 2. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
