To provide a heat pump type water heater capable of shortening a defrosting operation time, by increasing a defrosting heating capacity for defrosting the frost formation on an air refrigerant heat exchanger, while controlling the complication of a structure and an increase of a manufacturing cost.
The heat pump type water heater includes a heat pump water heater outdoor unit 1. The heat pump water heater outdoor unit 1 has: an outdoor unit water circuit where a hot water is made to flow; a compressor 2 for compressing a refrigerant; a water refrigerant heat exchanger 8 for performing a heat exchange between the refrigerant and the hot water of the outdoor unit water circuit; an air refrigerant heat exchanger 7 for performing the heat exchange between the refrigerant and the air; a blower 6 for ventilating the air refrigerant heat exchanger 7; a blower chamber 15 for housing the blower 6; and a blower chamber water pipe 46 arranged in the blower chamber 15 and connected with the outdoor unit water circuit.
