<P>PROBLEM TO BE SOLVED: To provide a hot water supply device of a heat pump type, that can suppress worsening of feeling of a user in reheating operation of bathtub water. <P>SOLUTION: The hot water supply device 100 of the heat pump type includes: a tank 10 for storing water for hot-water supply used in hot-water supply; a heat pump unit 20 which heats the water for hot-water supply before returning the water for hot-water supply from the lower part in the tank 10 to the upper part; a bath circulation pump 69 which circulates bathtub water, which is in the bathtub 82, in a bathtub water circulation circuit 71; a heat exchanger 72 for reheating which is arranged in the tank 10 and heats the bathtub water by heat-exchanging the bathtub water circulated through the bathtub water circulation circuit 71 with the water for hot-water supply in the tank 10; and a controller 40 which controls the output of the bath circulation pump 69 and adjusts circulation flow rate of the bathtub water. The controller 40 can change the output of the bath circulation pump 69 in accordance with a parameter using a bathtub water temperature in the reheating operation. <P>COPYRIGHT: (C)2012,JPO&INPIT |
