How can a metal rod save your hot water tank Visalia? Unknown to many homeowners, there are very intricate processes that take place inside your water heater system. While you are taking a bath or doing laundry, on the other side of the hot water tank is a metal rod shielding the water heater from all kinds of damage. What role does the anode rod play? Every water heater system, whether electric or gas water heater Visalia, consists of an anode rod. It is that part of the water heater, which is made of a steel core but coated with magnesium or zinc metal. Usually, it is incorporated into the appliance through an opening on the outside; hence, forming a connection between the rod and the interior walls. The anode rod is a core element of water heater systems as it prevents it from rusting. The Electrochemical Process To fully comprehend how the electrochemical process, you should have a rough idea of how metal corrodes. Corrosion occurs when a particular metal is oxidized; hence, causing it to deteriorate. Corrosion is a recurrent process. This is where the anode rods come in to prevent such corrosion. Typically, the metal used in making the anode rod is more active than the metal that the anode is protecting. This way, connecting the anode to the exposed metal using a volume of water does not lead to rusting. On the flipside, the anode rod is bound to rust with time. Ultimately, the active metal is eaten away, leaving your hot water tank prone to rust. For safety, you should replace the anode rod before it rusts. Choosing the best weapon Ideally, there are three kinds of water heater anode rods: magnesium, aluminum, and zinc anodes. Magnesium is the most commonly used material for new water heater models. The reason for this preference can be attributed to its efficiency in preventing rust. The only drawback of magnesium anode rods is with hard water. Aluminum anodes have better chances when working with hard water. However, they also have weaknesses. For instance, exposure to aluminum poses a health hazard. The zinc anode rod is made using aluminum. It also has traces of zinc, which help to counter effects of sulfur's pungent smell.
