Marathon water heaters carry a limited residential lifetime warranty. Each Marathon water heater features a high efficiency design that is lightweight and durable. Marathon water heaters make a great replacement water heater when your current water heater is leaking because they are guaranteed not to rust or corrode as long as you own your home. Rheem Marathon water heaters are made of unique cross-fiber polybutene creating a stronger and higher quality electric water heater with much longer life expectancy than regular steel electric or gas water heaters. Marathon water heaters come factory equipped with one fused upper heating element to protect against dry firing and a lower titanium plated water heater element that provides greater protection against lime and sediment build-up compared to copper or steel elements used in standard electric water heaters.
