Standard water heaters are equipped with the magnesium anode rods (identifiable by weld bead on the plug), and they work the best where water is not hard (softer). If the water is hard, magnesium anode rod in hot water heater do not last very long, usually couple of years. Magnesium anodes are used as they corrode at a faster rate than the iron.
