To provide a heat pump type water heater that can properly suppress an electric power consumption of a heat pump unit by means having simple constitution, and suitably allow the heat pump unit and a hot water storage tank unit to use a common electric power supply.SOLUTION: A heat pump type water heater A comprises control means 4, 14 which control a hot water storage operation to reserve hot water, heated using a heat pump unit U1, in a hot water storage tank 2, and the control means 4, 14 include stored hot water temperature upper-limit value setting means 14a which can set, as information related to a stored hot water temperature, an upper-limit value Tu of the stored hot water temperature set to be lower when an outside air temperature is low than when high so that in the hot water storage operation, an electric power consumption of the heat pump unit U1 does not exceed a predetermined value, the stored hot water temperature being controlled to below the upper-limit value Tu in the hot water storage operation.SELECTED DRAWING: Figure 1
