One of the most commonly found factors limiting the life of water heaters is interior corrosion. The water inside the heater tank can be very harmful to the system as the harsh minerals it contains can build up and eat away at the steel surfaces, a process which is only worsened by the high water temperatures.Known as soft water anodes, magnesium pencil anode rods are an excellent anode to protect the inside metal surface of the water heater tank from rust by electro-chemical action. The sacrificial magnesium rod (the anodes) corrodes in place of the tank (the cathode). The lifetime of a water heater can be greatly extended when the anode rods are replaced at regular intervals.Water heater anode rods are typically made of either aluminum, magnesium or zinc. Magnesium anode rods tend to be consumed quicker than aluminum or zinc anode rods due to the higher voltage they create during the sacrificial process. Despite this, magnesium anodes are an increasingly popular choice as dissolved magnesium in water can offer many health benefits.
