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
