Rheem-Ruud SP10869NL Resistor Element

The Rheem-Ruud SP10869NL is a high-performance resistor element designed for field service in heavy-duty electric water heaters. Featuring a 5000W 240V rating and a stainless steel (Incoloy 800) outer sheath, this low watt density (LWD) heating component is engineered to withstand scale buildup and reduce the risk of dry-firing failures. The integrated resistor is a critical feature for contractors, as it helps regulate the sacrificial anode rod depletion rate, significantly extending the service life of the tank lining in harsh water conditions. With a 19.24-inch insertion length and a 1-inch NPSM threaded connection, this direct replacement water heater element fits Rheem, Ruud, Richmond, and Vanguard models, ensuring a precise match for voltage and wattage requirements. This screw-in heating element provides consistent heat transfer and durable performance for high-demand residential and commercial plumbing applications.

Key Benefits

• Incoloy 800 Sheath: Provides superior resistance to corrosion and high-temperature oxidation.
• Internal Resistor Technology: Balances the electrical potential to preserve the magnesium anode rod.
• LWD Foldback Design: Distributes 5000 watts of power over a larger surface area to prevent sediment bonding.
• Universal Compatibility: Standard 1-inch NPSM threads and 1-1/2 inch hex head for standard socket wrench installation.
• Operating Efficiency: Rated for 3755W at 208V and 5000W at 240V to meet specific site electrical configurations.

Common Questions

Why should I use a resistored element instead of a standard copper one?
A resistored element like the SP10869NL is essential for glass-lined tanks. It prevents the heating element from over-consuming the protective anode rod, which maintains the integrity of the water heater tank and reduces long-term maintenance costs.

Can this element be used in a 208V electrical system?
Yes, this 5000W water heater element is dual-rated. When installed in a 208V system, it will output 3755 watts. Always verify the amperage rating of your circuit breaker and wiring before installation.

What is the cold resistance reading for a new SP10869NL?
Technicians checking for continuity should expect a cold resistance reading of approximately 11.5 ohms when the element is functioning correctly.
