Title: Hot water supply system
Inventor: SAWADA SHINYA
IPC: F24H1/18
Filed: 2008-02-29
Abstract: <P>PROBLEM TO BE SOLVED: To perform instantaneous water heating at a low cost by replacing hot water in a hot water delivery pipe in a circulation pathway with boiled water in a hot water supply system.  <P>SOLUTION: This hot water supply system 1 includes a water heater 2, the hot water delivery pipe 4, a return pipe 5 branched from the hot water delivery pipe 4 and connected to a water heater 2, a hot water delivery pump 51, and a control section 6 for controlling the water heater 2 and the like. The control section 6 has an inner volume holding section 61 holding a value of an inner volume of the hot water delivery pipe 4. The control section 6 sets a length of an operation time of a circulating operation necessary for replacing the hot water in the hot water delivery pipe 4 with the hot water boiled by the water heater 2 on the basis of the value of the inner volume and a hot water flow rate of the hot water delivery pump 51. As the control section 6 replaces only the hot water in the hot water delivery pipe 4 with the boiled hot water by performing the circulating operation, and the hot water in the return pipe 5 is not replaced, wasteful circulating operation can be prevented, and operation cost for instantaneous water heating can be reduced. Furthermore, as the length of the operation time can be set without installing a temperature sensor and the like, equipment cost can be also reduced.  <P>COPYRIGHT: (C)2009,JPO&INPIT
