Fact Sheet: Residential Heat Pump Water Heating
Residential heat pump water heaters (HPWHs) are two to three times more efficient than conventional gas and electric resistance water heating options. While HPWHs have been available as energy-efficient alternatives that cut greenhouse gas (GHG) emissions – and improve local air quality – for the past 15 years, they represent less than 1% of the water heaters sold in California. According to contractors and installers, however, small increases are starting to happen.
