This unit draws heat from surrounding air and transfers it to an enclosed tank. It also has traditional heating elements that can kick in when there is a high demand for hot water. It is one of America's most efficient water heaters; 67% more efficient than a standard tank. The GeoSpring has 4 different modes to choose from on it's convenient control panel, as well as a vacation setting.
Why Should I Care About Efficiency?
Water heaters are the 2nd highest energy user in the home. Standard tanks use more than the refrigerator, clothes washer, dishwasher and dryer combined. Switching to a more efficient tank may cost more upfront, but the energy savings will put that money back in your wallet in less than two years for a household of four.
As if this water heater isn't great enough, Puget Sound Energy is offering a large rebate for the installation of it. If you have this hybrid water heater installed and take advantage of the rebate it will result in being about the same cost of a traditional water heater. The conditions of the rebate can be found here.
