This report analyzes the economics and potential benefits of replacing fossil fuel water heaters with heat pump water heaters in multifamily buildings. Our analysis found that these retrofits could potentially save 175 trillion Btus per year, eliminate 6.5 million metric tons of GHG emissions, and provide 3.5 terawatt hours of potential load-shifting benefits to the electric grid. This report also describes existing and emerging heat pump water heater technologies for multifamily buildings, outlines supportive policies and utility programs, and provides recommendations for increasing the adoption of heat pump water heaters in multifamily buildings.
