Lochinvar & A.O. Smith 100110123 Heater Element

The Lochinvar & A.O. Smith 100110123 Heater Element is a heavy-duty 15kW commercial replacement designed for high-demand water heating systems. Engineered for 480V applications, this immersion heating element provides the rapid thermal recovery necessary for large-scale facilities. It features high-grade Incoloy nickel-alloy sheathing, which is specifically selected by technicians for its superior resistance to scaling, sediment buildup, and high-temperature oxidation. This medium watt density element replaces the obsolete part number 9004855105 and is the standard 60003-12 configuration for multi-element configurations. Built with forged steel flanges, it ensures a rigid, leak-proof seal under high pressure. This OEM water heater part fits standard 2-1/2-inch bolt-circle flanges, making it a drop-in solution for A.O. Smith DRE, DVE, and DHE series as well as Lochinvar CMC and SU series. Every unit includes a premium integrated replacement gasket to streamline installation and prevent service callbacks.

• Extreme Corrosion Resistance: The Incoloy alloy sheath prevents premature failure in hard water conditions by resisting pitting and stress corrosion.
• High-Efficiency Output: Rated at 15,000 Watts (15kW) and 480 Volts for optimized BTU recovery in commercial boilers and tanks.
• Universal Flange Fit: Designed for 2.5" bolt-circle patterns, compatible with both round and square flange mounts.
• Reduced Maintenance: Medium watt density design lowers the surface temperature of the element, significantly reducing lime and mineral accumulation.
• Precision Engineering: Features a 22-inch maximum "A" dimension to ensure proper clearance within the tank assembly.
