How a heat pump saves money

Instead of generating heat, a heat pump moves it from the air, like a fridge in reverse. That's why it uses roughly a third of the electricity of a standard electric storage system.

Run it on sunshine

If you have solar, set the heat pump to run in the middle of the day. Your hot water tank becomes a thermal battery, storing your spare solar as hot water.

Rebates take the sting out

Heat pump hot water systems attract a federal discount, and some states add their own. When you're ready, we'll match you with one verified, trusted installer in your area.
