Most heat-pump water heaters include an insulated tank equipped with an electric resistance element to provide backup heat whenever hot water demand exceeds the capacity of the heat pump. Since heat-pump water heaters extract heat from the air, they lower the temperature and humidity of the room in which they are installed. with an integral 50-gallon tank. Intended for residential use, the HP-50 operates in three modes: Energy Saver uses the heat pumpHeating and cooling system in which specialized refrigerant fluid in a sealed system is alternately evaporated and condensed, changing its state from liquid to vapor by altering its pressure; this phase change allows heat to be transferred into or out of the house.

Efficiency measure for rating the energy performance of dishwashers, clothes washers, water heaters, and certain other appliances. The higher the energy factor, the greater the efficiency. In some appliances EF reflects the percentage of energy going into the appliance that is turned into useful energy. 2.0); Normal mode, for higher demands, uses the heat pump and one of two electric-resistance elements (energy factor 1.5); and Electric Heat Only mode relies solely on the electric elements, functioning like a conventional water heater for particularly high demands. These 75.5”-high, 21”-diameter units have an operating range between 40°F and 120°F and come with automatic freeze/overheat protection.
