Abstract (en)
A heat pump water heater comprising a refrigerant circuit 2, a heat pump unit 1 and a hot water tank 41, wherein the heat pump unit 1 is disposed above the hot water tank 41 unit, and heat resistance R1 between the hot water tank 41 and the heat pump unit 1 is greater than heat resistance R2 between the hot water tank 41 and a side of the hot water tank 41 unit. It is possible to realize a water heater in which a heat radiation amount from an upper portion of the hot water tank 41 is reduced, a heat radiation loss from the hot water tank 41 is suppressed by minimum enhancement heat insulation, and energy efficiency is high.
