Zusammenfassung:A heat pump water heater system includes a water storage tank and a sealed heat pump cycle with a compressor, a condenser or gas cooler, an evaporator, and a refrigerant. The condenser/gas cooler is disposed in a heat exchange relationship with at least a portion of the water storage tank for heating water within the tank. The tank includes an outlet through which hot water is discharged, and a cold water inlet that is disposed so as to introduce cold water into the tank at a location of a bottommost portion of the condenser/gas cooler. The cold water introduced into the tank is not pre-heated by hot water in the tank so as to establish a thermodynamically efficient temperature differential between the cold water and hot water in the tank.
