To provide a heat pump water heater having improved transporting and installing properties.
The heat pump water heater comprises a refrigerant circuit constructed by connecting a compressor 31, a radiator 32, a restrictor 33 and an evaporator 34 together in sequence via refrigerant pipes, a water flow path 73 for heat exchange with the radiator 32, and a first hot water storage tank 36 and a second hot water storage tank 37 for storing hot water generated by the heat exchange. A box body storing these structural elements is separated into a first box body 71 for storing the refrigerant circuit and the first hot water storage tank 36 and a second box body 72 for storing the second hot water storage tank 37. The individual box bodies are reduced in size and weight while securing the supply amount of hot water in the tanks, resulting in improved transporting and installing properties.
