An entire day dedicated to heat pump water heater (HPWH) education and awareness. We know that collectively we have the power to create a clean energy, low-carbon future. On HPWH Day we connect with advocates, manufacturers, installers, homebuilders, and HPWH owners to showcase ENERGY STAR certified HPWHs and the ways they help create a better future.
