1" Stainless Steel Resistored Screw-In Element, 240 V

Rheem SP10869ML – 4500W, 240V Stainless Steel Resistored Screw-In Heating Element

The Rheem SP10869ML is a 4500-watt, 240-volt screw-in resistored heating element engineered for direct replacement in electric water heaters requiring stainless steel elements. This low-watt density component is built to extend the operational life of the water heater by minimizing scale accumulation, making it particularly effective in areas with hard water.

Constructed from high-grade stainless steel, this element resists corrosion and provides long-term reliability under demanding thermal conditions. The resistored design reduces dry-fire burnout and contributes to consistent recovery performance, making it well-suited for professional service and retrofit work.

Key Features

• Low-Watt Density: Delivers reduced surface temperature, minimizing calcium buildup and improving heat transfer longevity.
• Stainless Steel Sheath: Provides enhanced corrosion resistance compared to copper or zinc-coated elements, especially in aggressive water environments.
• Resistored Core: Designed to limit surge currents and mitigate the risk of premature failure.
• Screw-In Mounting: 1-inch NPSM threaded base with gasketed design allows straightforward replacement in compatible flanged ports.
• OEM Compatibility: Matches specifications for select Rheem, Ruud, and Richmond electric water heater models.

Technical Specifications

• Part Number: SP10869ML
• Wattage: 4500 Watts
• Voltage: 240 Volts AC
• Element Type: Screw-in, resistored, stainless steel
• Thread Size: 1" NPSM
• Application: Electric water heaters (Rheem-compatible)

Installation Considerations

Installation requires access to the tank's element port and proper sealing with a new gasket. Ensure that the tank is fully drained and power is disconnected before performing service. A standard 1½" socket wrench for elements is typically required. It is strongly recommended that replacement be performed by a licensed plumbing or electrical professional to ensure code compliance and operational safety.

For Contractors

The SP10869ML offers a reliable field solution for service calls involving element failure, dry-firing, or poor recovery performance. The resistored stainless configuration is particularly effective for extending element service life, reducing callbacks in high-mineral water regions.

Performance Advantages

• Long Service Life: Resists pitting and scaling in high-demand installations.
• OEM Quality: Manufactured to match Rheem factory specifications for thermal profile and thread engagement.
• Improved Safety: Resistored element lowers inrush current, helping prevent electrical arcing during cycling.

Summary

The Rheem SP10869ML is a professional-grade replacement element that delivers high thermal performance with enhanced resistance to corrosion and dry-firing. Its stainless steel construction and low-watt density design make it ideal for long-term reliability in both residential and light commercial water heaters.
