How does a powered anode rod work

Here at Brothers Plumbing, Heating and Electric, our water heater professionals can install and maintain power anode systems. These systems help protect the steel water heater tank from corrosion. Powered anode rods can lengthen the service life of your home water heater.

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.

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. A powered anode related to electricity being fed into the anode to impose a flow of current rather than relying on natural electrolysis. The length and size of the anode, as well as the current sent by the rectifier will influence the life expectancy of the anode. Corro-Protec anodes have been designed to work for more than 40 years, no matter how hard your water is.

They use electrical current to replace the loss of electron inside the hot water tank happenning because of the corrosion process.

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.

Powered anode rods, also known as impressed current anodes, are advanced corrosion prevention devices that can be used in water heaters. They are designed to provide longer-lasting protection to the tank than sacrificial anodes by reducing the corrosive action of hot water on the metal tank. Galvanic corrosion occurs when two different metals are in contact in an electrolyte water in this case , with one metal the anode corroding to protect the other the cathode. In traditional water heaters, a sacrificial anode made of a more reactive metal such as magnesium or aluminum is installed. This anode sacrifices itself by corroding first, thereby protecting the steel of the water tank. However, these sacrificial anodes eventually get completely consumed and need to be replaced, otherwise, the water tank starts to corrode. In contrast, powered anode rods work on a different principle called impressed current cathodic protection.

How does a powered anode rod work

A water heater powered anode rod acts like the sacrificial anode rod. It prevents rust from eating away at your water heater tank. They are both suitable for a wide range of water heaters. But does one outperform the other? All water heaters have a small component called an anode rod. You will hear this essential water heater part referred to as sacrificial. The metal used to make these anode rods is weaker than the rest of your water heater tank. Rust attacks weaker metal first.

Explain the informations you are looking for. Note that you don't need nearly as much torque to tighten as they do when they torque the ones from the factory. Buy It Now. What i can't say is whether the "short" anode rod makes any practical difference in the typical application on a home water heater tank, or even matters in edge cases very tall water tank, short anode, water electrical conductivity very low. Search Advanced search…. Last edited: Nov 12, The current supplied by the FixOdor powered anode will stops the bacteria that create the smell in the hot water tank. Total: 6 members: 0, guests: 6. All you have to do is follow our step-by-step installation guide to replace your magneisum anode rod with our FixOdor powered anode rod. Get the most durable and versatile anode available. Some high-end powered anode also offer audible alarm on the control module to let you know if the powered anode rod stops working. After that period, you only need to replace the anode rod. If current goes out, protection will reduce until current is coming back.

A lot of people take their water heater for granted, assuming they can install it and simply forget about it. For the most part, this is true. Tank style water heaters are fairly simple devices and do fine with a minimum of maintenance

How Power Anodes Work A powered anode relies on electricity being fed into the anode to impose a flow of current rather than relying on natural electrolysis. You don't need a lot of torque. He showed up early and was very professional. A powered rod will prevent this reaction. Install the app. Perhaps it is implied in your response, but you didn't say it. I got the new one under warranty. It has an extendible titanium wire to allow you to adjust to the height of the WH. When two different metals are connected or bonded , a current flows from one metal to the other. FixOdor relies on current to completely stops corrosion inside your water heater.
