Do Heat Pump Water Heaters Work in Cold Climates?

Yes, today’s heat pump water heaters work efficiently - even in cold climates.

Heat pump water heaters (or “electric hybrid” water heaters) operate best in spaces where surrounding air temperature remains at or above 40°F. Hybrid models will continue to make hot water even if surrounding air temperature dips below 40°F. ENERGY STAR certified water heaters can be installed in a wide variety of locations, from basements in Maine to garages in Southern California. Most models can be installed in the same location as your existing water heater.

Today’s heat pump water heaters are more advanced than ever.

Recent advances in heat pump technology have paved the way for today’s ENERGY STAR certified electric hybrid water heaters. They generate lots of hot water at a fraction of the cost of standard electric water heaters. In fact, ENERGY STAR certified heat pump water heaters can save a household of four an estimated $425 per year and over $3,700 over the life of the equipment. Many available models come with 10-year manufacturer warranties for added peace of mind.

The right choice for every house.

Heat pump water heaters come in different shapes and sizes. Most models are all-in-one, meaning the heat pump mechanism and storage tank come together as one self-contained package. Split-type heat pump models, on the other hand, have an indoor storage tank coupled with an outdoor compressor.

Split-type heat pump water heaters work in temperatures as low as -25°F.

Split heat pump water heaters are an option for almost any climate. These units heat water by extracting warmth from the outside air and many can do so at temperatures as low as -25°F thanks to advanced refrigeration technology. Split heat pump water heaters provide even greater flexibility for installation without sacrificing performance or efficiency.

Split heat pump water heaters, like the one pictured here, have an indoor storage tank coupled with an outdoor compressor. These ENERGY STAR models efficiently heat water even when outdoor temperatures dip to -25°F. Heat pump water heaters are an excellent way to save energy and work efficiently even in cold climates.
