What is the purpose of powered anode rod?

Published and updated

Our response

The purpose of a powered anode rod goes beyond preventing corrosion. It’s a comprehensive solution that addresses various common water heater issues, enhancing the longevity and efficiency of your heater.

  1. Eliminating Odors: Powered anodes, unlike sacrificial ones, can help prevent the unpleasant “rotten egg” smell often associated with water heaters. This smell is caused by the reaction of bacteria with the sacrificial anode, producing hydrogen sulfide gas. Powered anodes inhibit this reaction, thus preventing the odor.
  2. Reducing Air in Hot Water: A powered anode rod can help to mitigate the problem of air in your hot water system. This is a common issue caused by the interaction of water with the sacrificial anode, resulting in the production of hydrogen gas. Powered anodes significantly reduce this reaction, thus minimizing the air in your system.
  3. Preventing Sediment Buildup: Sediment buildup at the bottom of the tank is often a result of the sacrificial anode’s degradation. Powered anodes don’t degrade, hence, they help to prevent sediment buildup, leading to a more efficient water heater.
  4. Minimizing Noises: The operation of a powered anode rod can help reduce the noises that come from a water heater. These noises are often caused by the popping and hissing sounds of steam bubbles formed by the sacrificial anode’s interaction with the water. Since powered anodes don’t interact with the water in the same way, they help to minimize these noises.

A brand like Corro-Protec provides high-quality powered anodes that effectively address these issues, enhancing the performance and lifespan of your water heater. Their powered anode rods are not only designed to last over 20 years but also provide peace of mind by tackling these common water heater problems.
