Water Heater Rebates and Sales


Valley Rural Electric Cooperative offers rebates to members who purchase a new electric storage tank water heater. The amount of the rebate varies by the brand and size of the device.

Rebate Offers

  • For Marathon® water heaters:
    • A rebate of $3 per gallon (for tanks from 40 to 79 gallons)
    • A rebate of $4 per gallon (for tanks that hold 80 gallons or more)
  • For non-Marathon water heaters:
    • A rebate of $2 per gallon (for tanks from 40 to 79 gallons)
    • A rebate of $3 per gallon (for tanks that hold 80 gallons or more)


To qualify for a rebate, a member must meet several requirements.

  • The water heater must have a capacity of 40 gallons or higher.
  • The tank's energy factor must be 0.9 or higher.
  • The member must supply the co-op with a copy of the invoice or receipt.
  • The member must agree to participate in the co-op's demand response program.


Valley REC offers to members Rheem® Marathon® electric storage tank water heaters for purchase. Prices for non-members are slightly higher. The water heaters are available in sizes ranging from 30 gallons to 105 gallons. These highly efficient units are a great fit for the co-op's demand response program because power can be shut off to them during load control periods with minimal heat loss. Marathon units of 40 gallons or larger also qualify for the co-op's rebate program.
