You have a water heater with a LIFETIME warranty?
Yes, we do. It is called the Marathon. The Marathon is a special water heater that has a seamless blow molded polybutene inner tank. It will not rust. The several inches of foam insulation give it up to 0.94 energy factor. Tank sizes range from 15 gallons to 105 gallons to fit any household need. Once you purchase this water heater, the lifetime warranty is extended to the original owner when installed in a residential application.
