Description
Sacrificial Anode Rods For protecting solar water heater tanks A sacrificial galvanic anode rod is used to prevent corrosion to a more noble metal. When attached to the noble metal, the anode will corrode before the noble metal will corrode. In relation to a water heater application, the sacrificial anode rod is inserted into the tank and the metal it is protecting, the inside of the tank, is not going to corrode unless the anode rod corrodes away first. Anode rods must be checked yearly for corrosion. If the rod has corroded a significiant amount, then it must be replaced with a new anode rod. If the anode rod is changed out ceaselessly as needed, the tank’s lifetime will on a regular basis expand from years to decades. The Different Types of Anode Rods The kind of anode rod chosen for a water heater depends on water quality. Magnesium rods are intended for soft water or not-so-hard water applications. As it corrodes, magnesium will dissolve into the water, making a healthy water for drinking. Aluminum rods are used for hard water or even salt water applications. Aluminum rods mixed with zinc will assist eliminate sulfur dioxide smells (rotten eggs) from water, so as to be present when there is heavy amounts of Iron in the water.
