During a defrosting operation, the connection is switched to one of the connection passages 20, 21, 22 by the connection passage switch means 30 according to detection of the temperature of the hot water at the plurality of different height positions of the hot water tank 16. The hot water in the hot water tank 16 is taken out through the one of the connection passages 20, 21, 22 switched. The hot water taken out is passed through a heat exchanger 41 and returned to the bottom of the hot water tank 16. The hot water is taken out from a certain height position of the hot water tank 16 and used for the defrosting operation. Medium temperature water remaining in the hot water tank 16 is taken out and the heat of the medium temperature water is used effectively for the defrosting operation. By taking out the medium temperature water and using it for the defrosting operation, the temperature of the medium temperature water is lowered and the boiling efficiency of the heat pump unit 40 is increased for subsequent boiling.
