Build an "All-Electric" Home and receive a FREE 85 gallon Rheem Marathon water heater

Cooperative members are able to purchase high efficiency, Marathon electric water heaters at very competitive prices. The cooperative, in conjunction with East River Electric, offers a $6.00 per gallon rebate on all Marathons purchased by members. In addition, members will receive up to $6.00 per month credit on their electric bill by having the Marathon connected to the load management system. Union County Electric carries three sizes on hand - 50, 85 and 100 gallon models.

All Marathon water heaters come with a lifetime warranty against tank leakage and a six year warranty from the manufacture date on all components for the original owner. If the home in which the Marathon is originally installed is sold, a transferable 15 year warranty is available. The Marathon features Envirofoam insulation which is environmentally friendly and provides an R-value up to 26 so the hot water stays hot reducing running time for the heating elements. The polybutylene inner tank cannot rust or corrode and the low-watt density elements are made to withstand harsh water conditions.

The Marathon electric water heater - the last water heater you'll ever have to buy!

Unmatched Durability

Our patented insulation process, seamless liner and tough outer jacket make Marathon the most durable in the business
