Lochinvar & A.O. Smith 100110124 Heating Element

The Lochinvar and A.O. Smith 100110124 480V 18KW Heating Element is a heavy-duty, screw-in replacement engineered for industrial-grade commercial electric water heaters and boilers. Designed for high-demand applications, this 4500-watt density element features an Incoloy sheath to resist scale buildup and prolong service life in harsh water conditions. As a direct OEM replacement part, it ensures precise fitment and thermal transfer efficiency for Lochinvar SY and A.O. Smith DRE/DVE models. When diagnosing water heater recovery failure or high amp draw issues, this 18000-watt heating element provides the specific resistance required for 480V three-phase systems. Proper torque and a new gasket are essential during installation to prevent flange leaks or dry-firing. This component is critical for maintaining peak performance in commercial hot water systems where downtime is not an option.

Common Questions

Is the 100110124 element compatible with single-phase systems?
This element is rated for 480V and is typically utilized in three-phase commercial water heaters; always verify your unit's wiring diagram and voltage rating before installation.

What causes an 18KW element to fail prematurely?
Scale accumulation and sediment buildup are the primary factors. Regular tank flushing and ensuring the element is fully submerged before energizing the circuit prevent "dry-fire" failure.

Does this element include the replacement gasket?
Technicians should verify the presence of the O-ring or flat gasket in the assembly to ensure a watertight seal against the tank bung.
