Lochinvar & A.O. Smith 100142501 Heat Element

When you are onsite and dealing with a failed 6000 Watt Screw In Heat Element, getting the exact OEM replacement is the only way to ensure the system returns to its design performance specification. The Lochinvar & A.O. Smith 100142501 is a high-output 6kW heating element engineered specifically for heavy-duty commercial and residential water heating applications. Built with a copper-sheath and tin coating, this screw-in water heater element provides superior thermal conductivity and resistance to lime scale buildup in hard water conditions. As a Lochinvar replacement part, it integrates seamlessly with A.O. Smith electric water heaters, maintaining the precise heating element wattage required for rapid recovery times. This 240V/480V compatible component is a direct fit for HVACR technical parts inventories, allowing for a clean 1-inch NPSM thread installation without the need for flange adapters or heavy modifications. This is a critical water heater repair part for maintaining consistent BTU output and operational efficiency in high-demand environments.

Key Benefits for the Technician:

• Maximum Heat Transfer: The 6000 watt rating ensures high-density thermal output for rapid water temperature recovery.
• OEM Compatibility: Specifically designed as a 100142501 element for Lochinvar and A.O. Smith units, ensuring a perfect seal and electrical match.
• Durable Construction: The tin-coated copper sheath resists corrosion and mineral accumulation, extending the service life in harsh water conditions.
• Standardized Threading: Features a standard 1-inch screw-in base for universal compatibility with most commercial water heater tanks.

Common Technical Questions:

Is the 100142501 compatible with 208V systems?
While this is a 6000 watt element typically rated for 240V, using it on 208V will result in a lower actual wattage output (approximately 4500W). Always verify the nameplate voltage of the heater before installation to ensure the electric water heater element meets the required heat load.

Can I use this element to replace a lower wattage part?
Increasing the heating element wattage can overload the circuit breaker and wiring. Only replace with a 6kW element if the original specifications and the electrical service of the building support the 25-amp draw per element.

Does this include the gasket?
Standard practice is to replace the heating element gasket (GKT2513 or equivalent) during any element swap to prevent high-pressure leaks once the system is pressurized.
