Lochinvar & A.O. Smith 100108290 Heating Element

The Lochinvar & A.O. Smith 100108290 Heating Element is a heavy-duty, 240V 4500W water heater element designed for high-efficiency thermal transfer in residential and light commercial applications. This 12-inch copper heating element features a Corrogard zinc-plated finish to provide enhanced resistance against corrosive water conditions and sediment buildup. For field service technicians, this unit is a direct OEM replacement part and is technically identical to 9000095015, ensuring seamless water heater element compatibility across a wide range of Lochinvar, A.O. Smith, State, and Reliance brands. This screw-in heating element simplifies the replacement process in standard 1-inch and 1-1/2 inch ports. Utilizing a mid-line watt density design, it balances rapid recovery times with long-term sheath integrity. Always verify tank saturation before restoring power to prevent dry-fire failure of the 4500 watt 240 volt element during commissioning.

• Corrogard Protection: The zinc-plated copper sheath is specifically engineered to resist scaling and galvanic corrosion in aggressive water environments.
• OEM Compatibility: Replaces 100108290 and 9000095015, maintaining the original equipment manufacturer's performance and safety specifications.
• Optimized Recovery: The 4500W output provides a high BTU-per-hour transfer rate, essential for maintaining consistent hot water delivery in dual-element configurations.
• Universal Screw-In Design: Standard threading and an included gasket ensure a leak-proof seal and straightforward installation for HVACR contractors.

• Can this element be used in a 208V system? Yes, however, when operated at 208V, the output will drop to approximately 3500W. Always confirm the application requirements before down-rating.
• What tool is required for installation? A standard 1-1/2 inch element wrench or deep well socket is required to properly torque the hex head without damaging the flange.
• Is the gasket included? Yes, this replacement heating element ships with the necessary rubber gasket to provide a secure, watertight seal.
