What Is an Anode Rod, and Why Is It So Important?

There is no way in which to overstate just how important your water heater is. Just think of everything that you use hot water for around your home. When you wash your linens, run the dishwasher, or take a hot shower in the morning, you are relying upon your water heater to provide you with a bountiful supply of hot water. That is why it is so important that you do everything you can to ensure that your water heater remains in outstanding working condition. If you use a tank water heater in Bloomington, IL, that means keeping a high-quality anode rod in your hot water tank.

An anode rod is a rod that resides in your hot water tank. This rod is made from magnesium or aluminum, generally. Magnesium rods are more expensive, but are also preferred for their performance quality. The job of the anode rod is very straightforward. It protects your hot water tank from corrosion by basically offering itself up as a sacrifice. The rod attracts corrosive elements in the water in your hot water tank, so that it will corrode before the interior of your tank does.

It is important that your anode rod is checked from time to time, as a corroded rod means that your water tank is once again at risk. Most modern hot water tanks are steel with a thin glass lining, but this can crack and expose the steel to water. Magnesium rods may outperform aluminum rods, but they also tend to have shorter lifespans.

Once your water tank starts to corrode, it’s serviceable lifespan is pretty much over and done with. Keeping a fresh anode rod in place is much less of a financial burden than replacing a corroded tank. If you have any questions at all, give a member of our staff a call today.
