If you’ve never heard of sacrificial anodes, then the concept of powered anodes may sound like something out of a science fiction movie. However, these innovative devices have been making waves in the industry for quite some time now.
A Different Approach to Water Heater Protection
Most water heaters on the market use sacrificial anodes. These anodes are inexpensive, durable, and require no electricity. As water fills the tank, a chemical reaction occurs between the anode and the steel tank. This reaction protects the tank by directing ions from the anode to the steel, preventing rust. However, sacrificial anodes eventually wear out, leading to potential tank corrosion.
In contrast, powered anodes, also known as impressed-current anodes, work on an entirely different principle. Rather than relying on a sacrificial reaction, these anodes draw ions from an AC outlet to protect the tank. This means they don’t get used up over time. Although powered anodes are less common in water heaters, they have been widely utilized in various industrial applications.
The Advantages and Considerations
While powered anodes offer unique benefits, they also come with a few caveats. For regular water heater situations, they may not be cost-effective due to their higher price and potential for breakage. Additionally, powered anodes require electricity to function, rendering them ineffective during power outages. However, most outages don’t last long enough to cause significant damage. It generally takes several months without proper anode protection for a water heater to rust to the point of leakage.
But where powered anodes truly shine is in situations involving water softeners and odor problems. Water softeners, by exchanging salt for hardness, increase water conductivity. This puts more strain on sacrificial anodes, causing them to wear out faster. In addition, if there are sulfur or anaerobic bacteria present in the water, they can contribute to unpleasant odors. Powered anodes, on the other hand, only focus on protecting the water heater from rust without generating any odors. While they don’t eliminate odors or kill bacteria, they prevent the odor problem from occurring during their operation.
A Smarter Solution
Considering the advantages of powered anodes, they offer an elegant and cost-effective solution to combat smelly hot water and premature tank failure caused by water softeners. Instead of constantly replacing water heaters, homeowners can rely on powered anodes to extend the lifespan of their tanks. Of course, other solutions like Rheem’s Marathon plastic-lined electric water heaters or tankless heaters are also available, but they come at a higher price point than powered anodes. Other alternatives, such as UV systems and well chlorine injection, may work in some cases, but their effectiveness is less certain.
