Lochinvar & A.O. Smith 100208654 Rod

Protect your commercial water heating assets with the Lochinvar 100208654 Magnesium Anode Rod. This 1 x 24-inch sacrificial rod is a critical component for maintaining tank integrity in Lochinvar Shield SNA285-500 models and high-capacity A.O. Smith commercial water heaters. As a veteran-grade magnesium anode rod, it provides superior cathodic protection compared to aluminum alternatives, especially in soft to moderately hard water conditions. The 1-inch NPT connection ensures a secure, leak-free fit into the tank's tapping, while the 24-inch length provides ample surface area for attracting corrosive elements that would otherwise compromise the steel tank lining. For contractors servicing CHV 150-200 gallon or CHH 250-300 gallon Hi-Power units, this OEM replacement part is the standard for preventative maintenance. Regularly replacing a depleted water heater anode rod is the most cost-effective way to prevent premature tank failure and ensure the long-term reliability of a commercial hot water system.

• Magnesium composition offers the highest electrochemical potential for aggressive corrosion defense.
• Exact OEM fit for Lochinvar Shield and A.O. Smith commercial units simplifies field installation.
• 1-inch NPT threads provide a standard interface without the need for specialized adapters.
• 24-inch sacrificial length is optimized for high-volume commercial storage tanks.
• Corrosion mitigation prevents the buildup of rust and sediment, maintaining system efficiency.

When should this 100208654 rod be replaced during maintenance?
Technicians should inspect the rod annually. If more than six inches of the core wire is exposed or if the rod has thinned to less than 1/2-inch in diameter, it has reached its depletion point and requires immediate replacement to maintain tank protection.

Is this rod compatible with other brand tanks?
While primarily designed for Lochinvar and A.O. Smith Shield series, any commercial tank utilizing a 1-inch NPT port can physically accept this rod, provided the 24-inch clearance is available within the tank interior.

Why choose magnesium over aluminum for this specific part?
In most commercial applications, magnesium provides a more robust sacrificial reaction. It is preferred for its ability to protect the tank more effectively in a wider range of water chemistries without leaving the "jelly-like" aluminum hydroxide sediment often found with aluminum rods.
