Marathon Electric Water Heaters

The Marathon electric water heater is a seamless polybutylene plastic tank. 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.
