  • The upper heating element is protected against "dry-firing", and the lower element is made of stainless steel for longer life.
  • Seamless, blow-molded and lightweight polybutene tank that doesn't leak.
  • High efficiency (energy factor is 0.94), losses only 5 F of heat in 24 h.
  • First-hour delivery is 61 GPH, the recovery rate is 20 GPH.
  • As the Marathon doesn't have the metal tank, the anode rod is not needed, resulting in less maintenance involved and an absence of the hydrogen gases and rotten egg odor.
  • No rust, no corrosion due to the non-metallic water tank.
  • One of the most durable tank-type heaters in the water heating industry.
  • Bowl shaped bottom allows complete draining.
