PROBLEM TO BE SOLVED: To provide a hot water supply device for filling a bath with hot water in a short time while securing a sufficient supply amount of hot water. SOLUTION: When the bath is filled with hot water and hot water is supplied to a hot water supply passage at the same time, if the amount of hot water supplied to the hot water supply passage is insufficient, the filling of the bath is interrupted and hot water is supplied in priority to the hot water supply passage to secure the supply amount of hot water. The hot water already supplied to the bath is reheated during interrupting the filling of the bath, whereby it is prevented from cooling down. Thus, reheating is performed in a short time after finishing the filling of the bath and a shorter time is required for filling the bath. COPYRIGHT: (C)2005,JPO&NCIPI
