Magnesium anode Ø25 to the boiler heating element

The Magnesium Anode Ø25 mm for Water Heater Heating Element is one of the most important components for protecting a storage-type electric water heater from corrosion. Its primary function is to absorb the electrochemical corrosion that naturally occurs during the operation of the water heater. By acting as a sacrificial anode, it protects the inner tank, heating element (TEN), and other metal components from premature deterioration.

The anode is manufactured from a high-quality magnesium alloy that gradually dissolves during normal operation. This is why it is commonly referred to as a sacrificial anode—it corrodes instead of the steel tank, significantly extending the lifespan of the entire water heater. Timely replacement of the anode helps prevent costly repairs or complete replacement of the appliance.

The Ø25 mm magnesium anode is installed on the flange of the water heater heating element and is compatible with many models of domestic electric storage water heaters designed for this anode size. It effectively slows down corrosion, minimizes limescale buildup on the heating element, and helps maintain stable, efficient, and energy-saving operation.

Technical specifications:

• Anode diameter – 25 mm
• Mounting – M8
• Anode length – 200 mm
• Leg length – 220 mm
• Thread length – 15 mm
• Does not emit bad odor in water

Key Advantages

• Effectively protects the water heater tank against corrosion.
• Extends the service life of the heating element (TEN).
• Manufactured from high-quality magnesium alloy.
• Reduces limescale buildup on the heating element.
• Easy to install and replace.
• Compatible with many domestic electric storage water heaters.
• Ensures reliable and long-lasting operation of the water heater.

Applications

The Ø25 mm magnesium anode is designed for use in domestic electric storage water heaters equipped with flange-mounted heating elements that accommodate an anode of the corresponding size. It is intended for routine maintenance, repair, and replacement of worn sacrificial anodes.

Maintenance Recommendations

• Inspect the condition of the magnesium anode every 12–24 months, depending on water hardness and operating conditions.
• Replace the anode when it becomes significantly worn or has lost most of its magnesium material.
• When replacing the anode, it is recommended to clean the heating element and the inside of the tank from limescale deposits.
• Installing a new magnesium anode during every maintenance service significantly extends the service life of the water heater.

The Ø25 mm Magnesium Anode is a small yet essential component that plays a critical role in protecting your water heater from corrosion. Regular replacement helps prevent tank leaks, protects the heating element, reduces maintenance costs, and ensures reliable, long-term performance of the entire water heating system.
