Marathon water heater
The Marathon electric water heater features a technologically advanced design that offers superior efficiency and is guaranteed not to leak for as long as you own your home. The tank is made of a seamless Polybutylene that will never rust or corrode and is wrapped in 4 inches of Envirofoam® insulation. The inside is designed with a bowl-shaped bottom and an offset drain, creating a whirlpool effect that prevents sediment buildup. It’s clearly the most durable water heater made, and has a warranty to match.
