Rheem-Ruud SP10870QL Resistored Element

The Rheem-Ruud SP10870QL is a professional-grade 6000-watt, 480-volt resistored heating element specifically engineered for high-demand electric water heating systems. As a low watt density (LWD) component, it utilizes a foldback design to increase the surface area of the Incoloy stainless steel sheath, maintaining a watt density of approximately 84 W/in². This thermal profile is critical for reducing scale buildup and preventing localized overheating in hard water conditions. The resistored design is a key technical feature that balances the electrical potential between the element and the tank, effectively extending the service life of the sacrificial anode rod. Featuring 1-inch NPSM threads and a 1-1/2 inch hex head, this screw-in water heater element is a high-performance OEM replacement part compatible with Rheem, Ruud, Richmond, and most major commercial tanks. At 19.21 inches in length, it provides the robust heat transfer required for industrial and light commercial applications.

Key Benefits for Professional Installation

• Enhanced Corrosion Resistance: The Incoloy stainless steel construction resists high-temperature oxidation and chemical sheath failure.
• Advanced Thermal Management: The foldback configuration and low watt density minimize sheath temperature, reducing mineral calcification.
• Universal Tank Compatibility: Standard 1" NPSM threaded mounting ensures a precise fit for a broad range of 480V electric water heaters.
• Internal Resistor Technology: Protects the integrity of the water heater tank by regulating galvanic current flow.
• Comprehensive Kit: Each unit includes the necessary installation gasket for a reliable, leak-free seal.

Common Questions

Is the SP10870QL compatible with non-Rheem brands?
Yes, as long as the tank supports a 480V, 6000W configuration and utilizes a standard 1-inch NPSM screw-in port, this element serves as a direct replacement for brands like A.O. Smith, State, and Bradford White.

What are the benefits of a resistored element over a non-resistored version?
A resistored water heater element contains an internal resistor that limits the current between the element and the tank, which helps prevent premature anode depletion and protects the tank lining from electrolytic corrosion.

Can this element be used in a 240V or 208V system?
This is a 480V specific heating element. Installing it in a lower voltage system will result in significantly reduced wattage output (P=V²/R), which will lead to insufficient recovery times and poor equipment performance.
