The American Water Heaters Residential Hybrid Electric Heat Pump model HPE10280H045DV joins the class of the most efficient electric water heaters made. American Water Heaters estimates this water heater can save a family of 4 up to $360 per year in energy costs.
The American Water Heaters heat pump water heater uses a heat pump system that is very much like a refrigerator running in reverse to heat the water. The heat pump does not make heat, but instead takes heat from the ambient air in the room and pumps it into the water in the tank. The heat pump’s compressor uses only 850-watts to operate yet can transfer over three times the amount of heat into the water that the 850-watts of energy could make using resistance heating. The heat pump can also aid in cooling and dehumidification of the air in the room in addition to heating the water.
The American Water Heaters residential hybrid electric heat pump model HPE10280H045DV has an 80-gallon tank and has three standard modes of operation.
- The Efficiency Mode uses just the heat pump to heat the water yet if the ambient air temperature or, water temperatures are outside the optimum range for the heat pump will revert to using the resistance heating elements for water heating. In the Efficiency Mode the Energy Factor is 2.3 and a First Hour Delivery of 70-gallons is provided.
- The Hybrid Mode uses a combination of the heat pump and resistance elements heating the water to provide the most economical heating while meeting your needs. In the Hybrid Mode the Energy Factor is 2.3 and the First Hour Delivery is 84-gallons.
- The Standard Mode uses just the resistance elements to heat the water functioning as an ordinary electric water heater and is the least efficient mode of operation. In the Standard Mode the Energy Factor is .85 and the First Hour Delivery is 76-gallons.
The American HPE10280H045DV has a 4500-watt upper and 2000-watt lower element made of corrosion resistant Incoloy to provide resistance heating when conditions are not optimum for the heat pump or, water usage is higher than the heat pump can meet or, when Standard Mode is selected. There is also a function where you can program a vacation on the control panel. The vacation setting will maintain a 60-degree temperature in the water heater to prevent freeze damage.
