Marathon Water Heaters

Heating your water with an electric water heater is simple and efficient. The Marathon has at least two inches of polyurethane foam insulation around the entire tank - top, bottom, and sides for super insulation and that means super efficiency!

An electric water heater offers many advantages over propane or natural-gas units. An electric water heater is simple to install because it requires no gas piping or chimney.
