Lochinvar & A.O. Smith 100108283 Heating Element

The Lochinvar & A. O. Smith 100108283 Heating Element is a high-performance 4500W 240V water heater element designed for precision heat transfer in residential and light commercial applications. This screw-in heating element features an 11-inch insert length and is constructed from premium copper with a zinc-plated finish to enhance corrosion resistance against aggressive water conditions. Engineered as a genuine OEM replacement part, it ensures exact fitment and electrical compatibility with a wide range of Lochinvar, A. O. Smith, State, and American water heater models. Utilizing a high watt density design, this component provides rapid thermal response times to maintain consistent tank temperatures during high-demand cycles. The integration of 1-inch NPSM threading allows for a secure, leak-free mechanical seal when paired with the included gasket. Field technicians rely on the 100108283 for its ability to restore original equipment efficiency without the risks associated with generic after-market heating elements.

• OEM Compatibility: Guaranteed fit for A.O. Smith and Lochinvar series LT(A), LS(A), and LM(A) units.
• Durable Construction: Zinc-plated copper sheath minimizes mineral scale buildup and galvanic corrosion.
• Optimized Heating: 4500-watt output at 240 volts provides fast recovery for domestic hot water systems.
• Standard Fitting: Features a universal 1-inch NPSM screw-in thread for streamlined installation.
• Technical Reliability: Engineered to meet exact factory specifications for current load and thermal distribution.

What causes heating elements like the 100108283 to fail?
Failure is typically caused by scale accumulation on the copper sheath or "dry firing," which occurs if power is applied before the tank is completely full of water. Regular tank flushing is recommended to maximize component lifespan.

Can I use this element in a 208V system?
Yes, but the wattage will drop to approximately 3380W. For optimal performance in a commercial 208V environment, verify the specific recovery requirements of your system before installation.

Are the gaskets included with the replacement part?
Yes, this genuine OEM part typically includes the required rubber gasket to ensure a watertight seal upon installation.
