Marathon Water Heaters
As part of continuing efforts to provide quality products and services, SouthEastern Illinois Electric Cooperative can provide members and non-members with the best electric water heater on the market.
The Marathon electric water heater is a seamless polybutylene plastic tank, which is guaranteed not to leak or rust for as long as you own your home. Marathon water heaters are insulated heavily with a unique, trademarked "Envirofoam" insulation, which makes them incredibly energy efficient.
The exterior jacket of the Marathon is high-impact plastic, which resists dents, scratches, rust and corrosion. Models and prices of stocked items are listed below.
