The warranty length on a Rheem hot water heater depends on the specific model line and fuel type, as Rheem uses warranty duration to distinguish its product tiers. For standard residential tank water heaters, Rheem offers several warranty levels. The basic Performance series sold at Home Depot typically comes with a 6-year limited tank and parts warranty. The step-up Performance Plus series may have 6 or 9 years. The Performance Platinum, Professional, Professional Classic Plus, and Gladiator series often come with 9-year or 12-year limited tank and parts warranties. The premium Marathon series with a non-metallic polybutene tank offers a lifetime limited tank warranty and 6-year parts warranty. For point-of-use small tank models, warranties are often 6 years. For Rheem tankless gas water heaters, the warranty is usually 12 years on the heat exchanger, 5 years on parts, and 1 year on labor for residential use, though some high-efficiency models have 10 years on the heat exchanger. Commercial tank and tankless models have shorter warranties, typically 3 to 5 years. To keep the warranty valid, Rheem requires professional installation, product registration within a certain period, and proper maintenance, and labor coverage is typically only one year. Always read the warranty card that comes with your specific model for exact terms and exclusions.
