Lochinvar & A.O. Smith 100063315 Element

The Lochinvar & A.O. Smith 100063315 Element is a high-performance, 240V screw-in element engineered for high-demand commercial and industrial water heating applications. This 4500-watt heating element features a tin-coated copper sheath that provides exceptional resistance to corrosion and mineral buildup, ensuring long-term thermal efficiency in harsh water conditions. With a total length of 13.25 inches, this direct replacement water heater element (formerly part numbers ELE1408 and 100142494) is built to facilitate rapid heat transfer and maintain consistent tank temperatures. Designed for a precise fit in Lochinvar and A.O. Smith boilers and commercial units, it effectively handles 3750W at 208V, offering versatile compatibility across various voltage configurations. For field technicians and contractors, this OEM water heater part ensures your system operates at peak recovery rates while minimizing energy consumption and downtime. Its rugged construction and 1-3/8 inch hex head allow for high-torque installation without compromising the seal integrity of the tank flange.

Key Benefits:

• High-Wattage Performance: Delivers 4500W at 240V for rapid recovery and high-volume hot water demands.
• Superior Corrosion Resistance: The tin-coated copper sheath protects against aggressive water chemistry and scale accumulation.
• Broad Compatibility: Replaces legacy part numbers ELE1408, ELE1408K, and 100142494 in commercial and residential systems.
• Dual-Voltage Capability: Rated for efficient operation at both 240V (4.5kW) and 208V (3.75kW) cycles.
• Durable Screw-In Design: Standard 1-inch NPT threads and a 13-1/4 inch immersion length ensure a secure, leak-proof fit.

Common Questions:

Is the 100063315 element compatible with 208V systems?
Yes, while it is rated at 4500W at 240V, it functions as a 3750W element when installed on a 208V circuit, making it suitable for a wide range of commercial electrical configurations.

What indicates it is time to replace the water heater element?
Common signs include a significant drop in hot water recovery time, audible humming or "singing" from the tank during a heating cycle, or a tripped high-limit switch due to localized overheating from sediment buildup.

Does this element require a specific tool for installation?
Contractors should use a standard 1-1/2 inch element socket to ensure proper torque on the hex head without stripping the threads or damaging the tin coating.
