Water Heater Rebates

Save energy and money when you install a natural gas water heater. Receive $50 for a natural gas water heater, rated at .62 EF or higher or a tankless water heater rated at .80 EF or higher. The greater the efficiency, the greater your rebate. Whether you are replacing an existing water heater or installing a new one, a CenterPoint Energy rebate makes that purchase easier.
