AirGenerate A7 AirTap Water Heater Retrofit Heat Pump Review

The AirGenerate A7 AirTap Heat Pump is a retrofit heat pump that will fit any existing gas or electric tank type water heater from 30 to 80 gallons in size. Heat Pumps are actually only moving heat from one area to another not generating heat so they are highly efficient. The heat is moved using a refrigeration process that is running in reverse pulling heat out of the ambient air in the room where it is located and pumping the heat into the water heater where it is dispersed heating the water. The AirGenerate A7 AirTap Heat Pump draws only 720 Watts of power while it is running compared to 4500 Watts used by most common electric water heater elements. This wattage use by the A7 AirTap is approximately 1/6th of the power used by the conventional water heater element.  The AirGenerate A7 AirTap has a MSRP of $699.

Energy Star estimates that a heat pump water heater could save a 2.6 person household $290 per year on their water heating costs. This savings could be almost ½ of your water heating costs for the year. Actual performance of the heat pump is dependant on the ambient heat where it is installed. Using the heat pump in the southern tier states where the temperatures are higher the heat pump will be more economical 90 – 100% of the year vs. 60 % in the center tier states and 50% in the northern tier states. The heat pump water heater also offers fringe benefits. Removing the heat from the ambient air translates to cooling and with the cooling comes dehumidification. While saving money on heating your water you will also save on cooling and dehumidification costs.
