What is the heat pump water heater?
Heat pump water heaters use electricity to move heat from one place to another rather than generating their own heat like a traditional electric water heater. This makes them two to three times more efficient, according to the Department of Energy (DOE). Think of a heat pump water heater as a refrigerator working in reverse.
A refrigerator pulls heat from inside a box and dumps it out into whatever room it's in.
An Heat Pump water heater pulls heat from the surrounding air and dumps it, at a higher temperature, into a tank to heat water.
Heat pump water heaters are sometimes called “hybrid” water heaters because, during periods of high hot water use, they can switch to standard electric resistance heat automatically.
You can use your unit’s control panel to set the water heater to various settings, including hybrid mode. If you don’t want it to switch over automatically, simply set it to the regular heat pump mode.
