Product Description
46" Magnesium Anode Rod for Solar Water Heater Thermal Storage Tanks
The WNRLN WMR-ST46 is purpose-designed for the unique demands of solar water heating systems. Solar thermal storage tanks operate at consistently higher temperatures than conventional water heaters—often reaching 80-95°C during peak solar gain. Standard anode rods can exhibit accelerated consumption at these temperatures. Our heat-stabilized AZ63 alloy formulation maintains consistent electrochemical performance and protection efficiency across the full solar operating temperature range.
Key Features
- Heat-Stabilized Alloy: Maintains protection efficiency at temperatures up to 95°C
- Extended 46 Inch Length: Full coverage for tall solar storage tanks
- Solar Keymark Certified: Approved for solar thermal system components
- Consistent Protection: Stable performance across temperature cycling
- UV-Resistant Packaging: Suitable for outdoor solar equipment storage
