Marathon Collection 120V Residential Electric Point-Of-Use Non-Metallic Water Heater with 19.9 Gallon Tank
The Marathon electric point-of-use water heater shares many of the features that the larger Marathon water heaters have. So many of the questions have the same answer: Why would you want a non-metallic water heater? To start, how about easy installation and service? Marathon's lightweight tank is easy to maneuver and position. The tank bottom is bowl shaped, allowing it to drain completely. Want a tank that is impervious to rust and corrosion? The seamless, blow-molded, polybutene tank delivers. Is it durable? This tank's unmatched strength comes from its multiple layers of filament wound fiberglass. Lightweight? Check. Reduce energy consumption? The Polyurethane insulation helps there. Tough? How about a tough outer shell of molded polyethylene that resists dents, scratches and salt air. Dip tube? Made of high temperature polysulfone. Brass drain valve? Try full-flow brass drain valve, recessed so it is out of the way of brooms and scrubbers. Temperature and pressure relief valve? Standard. Even the heating element benefits from Rheem's years of water heater experience. The heating element is thermally fused to protect against dry-firing and its low watt density gives it a long life. Rheem brings all this together and backs it up with a limited lifetime warranty that's "...warrantied not to leak as long as you own your home."* And while the bigger Marathon unit might have you thinking this point-of-use is just a superhero sidekick, this water heater has a couple extra benefits. First, it's perfect for applications where larger water heaters won't fit, such as apartments, recreational property, and restrooms in offices and commercial buildings. Second, Rheem includes light duty commercial use in the warranty with 10 year limited tank and 1 year limited parts.
