Ready to buy a heat pump system? Get up to 3 quotes from pre-vetted installers

Powered by SOLARQUOTES*

Heat pump hot water systems are a growing energy-efficient option. Like a split-system air conditioner, they draw warmth from the air and transfer it into a storage tank, using electricity to move heat rather than generate it. Our review compiles data from manufacturer and retailer sites and checks each model’s WaterMark certification.

Not sure where to start? Read our hot water system buying guide to check which type of system (gas instant, gas storage, solar, electric storage or heat pump) is right for you.

About our partnership with SolarQuotes

ÌÇÐÄVlog has partnered with SolarQuotes to help you find and buy the right solar, battery, and EV charger for you. While we make money if you use SolarQuotes to find an installer, this doesn’t influence our ratings. 100% of the money we make goes directly back into our nonprofit mission.
