<P>PROBLEM TO BE SOLVED: To provide a hot water supply system which can reduce energy consumption by suppressing wasteful heat accumulation of hot water in a hot water storage tank while considering the use of a large amount of hot water to fill a bathtub. <P>SOLUTION: The hot water supply system includes a hot water storage tank 4 which reserves the hot water heated by a tank heating means 20, and a combustion water heater 3 which heats the hot water introduced from the hot water storage tank 4 by combustion at a burner 31. A boiling temperature setting means is provided which sets a boiling set temperature for filling on the basis of a temperature set by a filling temperature setting means when a current time is within a time zone set by a filling preparation time zone setting means, but sets a boiling set temperature for supplying hot water on the basis of a temperature set by a hot water supply temperature setting means if the current time is within a time zone set by a hot water supply operation time zone setting means, excluding a time zone set by the filling preparation time zone setting means. <P>COPYRIGHT: (C)2012,JPO&INPIT |
