The Electrification of Domestic Hot Water: Heat Pump Water Heater Adoption in U.S. Residential Construction

The residential construction market in the United States is undergoing a fundamental transformation, driven by the dual imperatives of grid modernization and enhanced indoor air quality. Central to this shift is the increasing adoption of Heat Pump Water Heaters (HPWHs). These highly efficient, all-electric systems represent a critical technology for decarbonizing buildings and fostering a more resilient energy infrastructure. While current national adoption rates remain modest, market dynamics indicate a significant acceleration, propelled by robust governmental policies, escalating consumer interest in new construction, and continuous technological advancements.
