Plug-In heat Pump Water Heater Field Study Findings & Market Commercialization Recommendations

Report / July 12, 2023 / Building Innovation

Water heating and space heating together account for two thirds of residential energy usage in the U.S. and should be the cornerstones of any plan to decarbonize the built environment. Emerging, plug-in 120-volt heat pump water heaters (HPWHs) are entering the market and proving themselves to be important new offerings from manufacturers aiming to address some of the key barriers. This study provides an overview of lessons learned on the first ever third-party field validation effort on the 120-volt HPWH technology through California-wide installations and includes a market assessment and recommendations for commercialization.
