<P>PROBLEM TO BE SOLVED: To prevent overshoot of a hot-water supply temperature even when the amount of hot-water to be supplied is suddenly increased immediately after the start of simultaneous hot-water supply. <P>SOLUTION: This hot-water storage type hot-water supply device includes a control means 27 (28, 29) for adjusting an opening degree of a first mixing valve 5 so that a temperature of hot-water/water detected by a first hot-water supply temperature sensor 9 reaches a predetermined first hot-water supply set temperature, and adjusting an opening degree of a second mixing valve 12 so that a temperature of hot-water/water detected by a second hot-water supply temperature sensor 16 reaches a predetermined second hot-water supply set temperature. The control means 27 starts supplying hot-water from a second hot-water supply pipe 14 by opening a switch valve 17 after temporarily changing the second hot-water supply set temperature to a temperature lower than the predetermined temperature, when starting supplying hot-water from the second hot-water supply pipe 14 during hot-water supply from the first hot-water supply pipe 7, if the second hot-water supply temperature is set at a predetermined temperature or higher. <P>COPYRIGHT: (C)2012,JPO&INPIT |
