Rheem Marathon 5 50 Gallon Electric Water Heater

Product Description

The RHEEM MARATHON 5 is a 50-gallon residential electric water heater built for long-term, reliable hot water delivery. This unit uses electric resistance heating elements to maintain stored water temperature and is designed for standard residential plumbing installations. The non-metallic tank construction common to the Marathon product line resists corrosion and eliminates the need for a sacrificial anode rod. Licensed plumbers and HVAC technicians handle installation in homes, light commercial spaces, and multifamily units where a high-capacity electric storage water heater is required.

The MARATHON 5 is suited for residential applications requiring a 50-gallon storage capacity. It fits standard utility closet, basement, and garage installations where a vertical electric water heater is the specified replacement or new-install solution. This heater is appropriate for homes with moderate-to-high daily hot water demand and is commonly spec'd by plumbing contractors on new construction and replacement jobs alike.
