Marathon Water Heaters

In the best interest of our members, Clay-Union Electric carries Marathon water heaters with a LIFETIME warranty. For new home construction or members converting from fossil fuels, or those replacing their old electric water heater, the Marathon water heater is the best option.

Heating your water with an electric water heater is simple and efficient. Marathon water heaters are non-metallic, which means your water heater will never rust out. The Marathon has at least three inches of polyurethane foam insulation around the entire tank; top, bottom, and sides!

An electric Marathon water heater offers many advantages over conventional electric, propane or natural gas units, such as:

  • A Marathon has a lifetime warranty on the tank. If the tank should ever spring a leak while at its' original point of installation, a replacement heater will be supplied at no cost for the new heater.
  • With over 3 inches of Envirofoam insulation surrounding the tank, heat loss is kept to a minimum, cutting you water heating costs

Rebate Program:

Clay-Union Electric offers the following rebates on Marathon electric water heaters.

  • $6.00 per gallon rebate on a Marathon lifetime warranted water heater
  • $6.00 credit on your monthly electric bill if you use over 600 kWh per month

The water heater must be connected to the load management system for rebate and credit.
