<P>PROBLEM TO BE SOLVED: To provide a storage type hot water supply device capable of suppressing degradation of coefficient of performance in a heat pump unit in increasing heat quantity of a bathtub by utilizing heat of warm water in a hot water storage tank. <P>SOLUTION: This storage type hot water supply device 100 includes a water supply/hot water supply circuit 50, a reheating heat exchanger 5, a bath water level sensor 61P, a bath temperature sensor 61T, and a controller 10. The water supply/hot water supply circuit 50 adjusts a temperature of warm water in the hot water storage tank 35 and supplies the same to a bathtub 70. The reheating heat exchanger 5 exchanges heat between warm water in the hot water storage tank 35 and warm water in the bathtub 70. The bath water level sensor 61P detects a water level of the bathtub 70. The bath temperature sensor 61T detects a temperature of the bathtub 70. The controller 10 adjusts the temperature of the warm water in the hot water storage tank 35 and supplies the same to the bathtub 70 by the water supply/hot water supply circuit 50, when a value of the bath water level sensor 61 is a prescribed value or less. <P>COPYRIGHT: (C)2011,JPO&INPIT |
