Features: _x000D_ 1. Magnesium rod, also known as anode rod, is mainly composed of magnesium. _x000D_ 2. In the water heater liner, it and the inner liner (mainly iron) are in contact with water at the same time. Due to the chemical principle, the primary battery is formed, which can prevent corrosion and scale. _x000D_ 4. When the water temperature exceeds 40, scale will be generated in the water heater. The combination of magnesium rod and iron can protect the inner container from corrosion. _x000D_ 3. Made of environmentally friendly magnesium alloy for durability _x000D_ 4.
