How does a powered anode rod work

The answer is YES. Since the sacrificial anode must sacrifice itself to protect the hot water tank, it is important that the anode is large enough to last for several years. However, the powered anodes rod do not work in the same way, so they are much smaller.

When purchasing a hot water tank, it is important to know that a sacrificial magnesium anode is installed by the manufacturer. This anode slows down corrosion but degrades quickly. To ensure adequate protection, you should change the magnesium anode every few months. However, this anode is about 4 feet long and since it is not easily replaceable, not many people take the time to do so. Those who decide to call a plumber to replace the anode are going to receive an expensive bill. Unlike sacrificial anodes, FixOdor impressed current anodes use electricity to prevent corrosion inside hot water tanks. Since electricity is an unlimited resources, the electric anode does not need maintenance and is designed to last more than 5 years.

When two different metals are connected or bonded , a current flows from one metal to the other. This action is called electrolysis and is true for all metals. When two different and bonded metals are placed in fresh or salt water, then the water will react with the higher noble metal first. One metal will oxidize away, while the other metal stays intact. This is a natural chemical reaction. In the case of water heaters, the water heater tank is made of steel.

A powered anode rod, also called electric anode rod relies on current to stop corrosion inside the water heater tank. If current goes out, protection will reduce until current is coming back. Traditional magnesium anode rod relies on the rod itself to reduce corrosion. Corrosion will attack the rod before attacking the tank. Those are also know as hex head anode rod. Cathodic protection is used to mitigate corrosion damage to active metal surfaces. Cathodic protection is used all over the globe to protect pipelines, water treatment plants, above and underwater storage tanks, ship and boat hulls, offshore production platforms, reinforcement bars in concrete structures and piers, and more. Sacrificial Anodes are highly active metals that are used to prevent a less active material surface from corroding. Sacrificial Anodes are created from a metal alloy with a more negative electrochemical potential than the other metal it will be used to protect.

I definitely wanted to know what goes on behind the scenes when it comes to the magic of these little rods, and you probably do too. It turns out there is no real secret. For a better explanation of how that happens, however, read on! Powered anode rods produce small electrical currents that scatter electrons before they can bind to and corrode a water heater tank. The currents also destabilize calcium molecules so that they cannot attach to the tank, thereby mitigating limescale buildup. At the lower end of a powered anode rod is the metal rod itself, which is made of titanium and is relatively thin.

OK, I had already purchased the shorter version because it was half the price and it claims to protect up to 80 gallons. That corrosion protection is a long term protection compared to old sacrificial magnesium anode rod factory-installed inside your tank. Click to expand Joe was on time and did a great job with the installation Ashley B. These rods are built to last longer than regular magnesium rods. Once the powered anode rod is connected to the power supply included inside the box, the corrosion inside the tank will be stopped completely. New posts.
