How a Powered Anode Rod Stops Water Heater Corrosion
How a Powered Anode Rod Works Quick Summary A powered anode rod replaces the traditional sacrificial anode with an electrically driven corrosion protection system. Instead of slowly dissolving into the water, it uses a small external power supply to protect the steel tank from rust. These systems can last the life of the water heater, dramatically reduce odor problems, and are especially effective in softened or high-temperature water. When properly installed and powered, it can significantly extend a water heater’s lifespan—but only if you understand how it works and where … Read More
How a Water Heater Anode Rod Works
Why Every Water Heater Needs an Anode Rod (And What Happens When It’s Gone) Quick Summary All tank-style water heaters contain at least one anode rod. The anode rod is designed to prevent corrosion from damaging the water heater’s steel tank. The metals most commonly used in anode rods are magnesium, aluminium, or an aluminum-zinc alloy. These metals are used because they corrode more easily than steel, so they corrode rather than the steel tank. Well, until the anode rod is gone, then the tank corrodes. In other words, anode … Read More
