ENERGY STAR® Natural Gas Water Heater Rebate application:

  • Natural Gas Water Heater Rebate(PDF)
  • Instant Distributor Rebates Now Available: Check if your contractor’s equipment quote already includes the rebate. HVAC equipment distributors can now automatically apply the Energize CT rebate to the price they charge your contractor for qualified equipment, eliminating the need for a mail-in rebate for that unit.  Simply ask your contractor if the rebate will be applied automatically or if you need to submit a rebate application through the mail. Multiple rebates for the same unit (equipment serial number) will not be accepted.
