A heat pump hot water apparatus of the present disclosure includes a heat pump cycle, a hot water storing tank, a hot water storing tank-dedicated heat exchanger, and a circulation pump. Further, the heat pump hot water apparatus includes outlet temperature detecting means for detecting a temperature of circulating water from a radiator, inlet temperature detecting means for detecting a temperature of the circulating water to the radiator, tank temperature detecting means for detecting a temperature of water in the hot water storing tank, and a control apparatus. In accordance with a reduction in a difference between a target heating temperature of the water in the hot water storing tank and the temperature detected by the tank temperature detecting means during a heating operation, the control apparatus adjusts a circulation amount of the circulating water so as to reduce a difference between the temperature detected by the outlet temperature detecting means and the temperature detected by the inlet temperature detecting means. |
