Rheem's Marathon Eclipse Medium-Duty non-metallic electric water heaters are designed for harsh environments and have the 10-year limited warranty to back it up. One of the most durable electric water heaters available, Marathon Eclipse is constructed of multiple layers of filament-wound fiberglass that give the tank unmatched strength. Non-metallic means no anode rod which means no smelly water normally caused by chemical reactions with sulfates. The polyethylene outer shell resists dents, scratches and salt air. Marathon Eclipse is available in 85 Gal. and 105 Gal. capacities.
