Lochinvar & A.O. Smith 100108358 Heating Element
The Lochinvar & A.O. Smith 100108358 Heating Element is a professional-grade OEM replacement part designed for high-performance residential and light commercial water heaters. This 120V 1650W element features a 10.75-inch immersion length and is constructed from high-quality copper (CU), providing superior thermal conductivity and scale resistance in standard water conditions. As a low-watt density heating element, it reduces surface temperature during operation, which minimizes mineral buildup and effectively extends the service life of the heater in Lochinvar JR and JT series models, as well as various A.O. Smith electric water heaters. For service contractors, this part ensures a precise fit and match to original factory specifications, maintaining the energy efficiency and recovery rate of the system. Whether you are performing routine maintenance or a critical repair, utilizing this genuine 100108358 water heater element ensures compatibility with the existing internal tank threads and electrical 120V circuits.
Key Benefits:
- Direct OEM Replacement: Ensures seamless compatibility with Lochinvar and A.O. Smith equipment, eliminating the risk of mismatched thread pitches or wattage ratings.
- Optimized Copper Construction: The 10.75-inch copper sheath offers rapid heat transfer and reliable performance in diverse water chemistry environments.
- Efficient 1650W Output: Perfectly balanced for 120V electrical configurations, delivering consistent recovery times and maintaining setpoint temperatures.
- Extended Component Life: The low-density design prevents localized hotspots, reducing the likelihood of premature burnout and sediment-related failures.
Common Questions:
Which models are compatible with this element?
The 100108358 is primarily designed for Lochinvar JR(A) and JT(A) models, as consistently specified in manufacturer technical charts, and serves as a direct replacement for part number 9000253015.
Does this include the sealing gasket?
In most service applications, it is standard practice to replace the element gasket (typically part 100108414) simultaneously to ensure a watertight seal at the 1-inch NPSM connection point.
Can I use a higher wattage element instead?
Engineers advise staying with the 1650W specification unless the circuit breaker and wiring are rated for higher amperage to prevent electrical safety hazards.
