Lochinvar & A.O. Smith 100108346 Heating Element

The Lochinvar & A.O. Smith 100108346 heating element is a high-performance 240V 3800W replacement component engineered for precision and durability in commercial and residential water heating systems. Featuring a 13.125-inch incoloy sheath, this low watt density heating element is designed to reduce sediment buildup and scale accumulation, which is critical for maintaining thermal efficiency in hard water conditions. The nickel base screw-in design (1-inch NPSM connection) ensures a secure, leak-free fit during field installation. As a genuine OEM water heater part, the 100108346 provides exact electrical specifications and physical dimensions required to restore system integrity without the risks associated with universal alternatives. This Sandhog element (cross-reference 9000225015) is the primary choice for technicians requiring a reliable A.O. Smith 3800 watt element that stands up to heavy cycling in high-demand environments. Verify the specific tank diameter and port clearance before threading the element into the heater.

• Enhanced Corrosion Resistance: The incoloy nickel alloy construction provides superior protection against high-temperature oxidation and chemical scaling.
• Reduced Maintenance: Low watt density design spreads heat over a larger surface area, significantly slowing mineral accumulation and extending the service life of the component.
• Precision OEM Fit: Guaranteed compatibility with Lochinvar and A.O. Smith units requiring a 13-1/8 inch immersion length.
• Easy Installation: Standard 1-inch NPSM screw-in base allows for straightforward replacement using a standard element wrench.

Is the 100108346 compatible with 208V systems?
While it will physically fit, operating a 240V element at 208V will result in a significant drop in wattage output (approximately 2854W), which may lead to slower recovery times. Always match voltage ratings for optimal performance.

Does this element include a gasket?
Yes, this OEM replacement kit typicaly includes the necessary rubber gasket required to establish a watertight seal upon installation.

Why choose incoloy over copper elements?
Incoloy is a specialized nickel-chromium alloy that handles "dry firing" and aggressive water chemistry much better than standard copper, making it the professional standard for longevity.
