The Marathon electric water heater offers these advantages:
Technologically advanced design is clearly differentiated from short lived steel water heaters.
It's the most durable water heater made, with a warranty to match
Envirofoam™ insulation is completely free of CFC and HCFC ozone depleting gases. Marathon leads the way in environmental friendly manufacturing, design and operation.
Tank comes complete with a factory installed vacuum relief valve, ¾" brass tee and ¾" brass nipple for easy, professional installations.
Replaceable brass drain valve
All wiring run in conduit for easy control wiring
Seamless blow molded polybutylene tank with no anode rod required for a corrosion free life
High temperature, commercial-grade diptubes for greater durability
The filament wound fiberglass outer tank is designed to be more flexible and withstand more pressure than conventional tanks
Our unique high temperature dip tube is offset from the concave bottom, creating a "whirlpool effect" which helps prevent sediment build-up
Every tank includes 4' of pipe insulation for even greater savings.
