Accelera Heat Pump Water Heater Incentives

Energy Star The U.S. Congress has, so far, failed to renew the federal tax credit for heat pump water heaters, or pass any new legislation. There are, however, a number of local government and utility rebates available across the country that the Accelera® qualifies for. A good place to look for rebates by region is the Database of State Incentives for Renewables & Efficiency website, DSIRE.
