Are powered anode rods any good?
Overall, there are quite a few advantages to using powered anode rods. They don't degrade, prevent smelly water (by killing anaerobic bacteria that leads to that rotten egg smell), and protect your hot water heater from corrosive elements in the water. Probably the best powered anode rod today is made by Corro-Protec.
What type of anode rod is best?
Magnesium anode rods are expected to work better in a home with soft water. Aluminum anodes are appropriate for homes with hard water and a high PH. Zinc anodes work best if a home is starting to smell like rotten eggs and is best for replacing water heaters that already dissolved.
Do anode rods work?
Anode rods are critical in extending the life of your water heater. Unfortunately, anode rods have life expectancies far shorter than their water heaters. While your average hot water heater will last 10 years, anode rods only have a 5 year life expectancy.
How does Corro-Protec powered anode rod work?
The Corro-Protec system includes a titanium anode and a current rectifier. When the rectifier is connected to the nearest outlet, the rod in the tank supply a small amount of current into the water heater. This current completely stops the loss of energy from all metals to which the ground is connected.
What is better magnesium or aluminum anode rod?
However, aluminum rods are the better choice for a water heater that heats up sulfate-tinged water. Sacrificial anodes change sulfates into hydrogen sulfides. When a magnesium anode rod is used, the level of hydrogen sulfide can get too high and cause a rotten-egg stench in your hot water.
How long will water heater last without anode rod?
The longevity of water heaters without anode rods is about: 5-8 years. The actual lifespan depends on water hardness, water heater type and quality, when the anode rod was removed, and how hot the water is. In extreme cases, the water heater may only last 3-5 years without an anode rod.
Can anode rod causing rotten egg smell?
The most common cause of smelly water is anaerobic bacteria that exist in some water and react with the magnesium and aluminum sacrificial anodes that come with most water heaters to produce hydrogen sulfide gas, making the classic rotten egg odor.
What is the best anode rod for smelly water?
zinc anode rodPreventative method #1: Use a zinc anode rod One way to prevent the hydrogen sulfide smell is to use a zinc or aluminum-zinc alloy anode rod. The reason is that zinc doesn't react the same way with bacteria as magnesium or aluminum (by itself).
How does a powered water heater anode work?
Powered anode rods work by neutralizing bacteria inside your water heater to preventing a “rotten egg” smell in your hot water coming from the tank. Powered anode rods work well at protecting the water heater tank against corrosion as well as controlling the bacteria inside your water heater tank.

If it doesn't begin to smoothly turn clockwise.
Does the length of an anode rod matter?
The length of the anode rod is important in the case of a sacrificial anode. Indeed, as its name suggests, it sacrifices itself to protect your tank from corrosion. As a result, the more magnesium or aluminum there is on the anode, the longer the protection time of your water heater will be.
Why does my hot water smell like rotten eggs?
The most common odor problem from water heaters is a rotten egg smell that comes out of your faucets and fixtures when running water. This smell is typically caused by sulfate bacteria that can develop within the tank.
What is an anode made of?
Made of titanium, the anode is covered with MMO (Mixed Metal Oxides) which will offer better conductivity. The MMO is made up of different metals and the manufacturers seem to want to keep their mixture confidential. It is very important to check the width, length and thickness of the rod portion which is covered with MMO to conclude its service ...
Why do anodes smell?
Smelly Water. Powered anode rod are very popular because they stop the sulfur smell in hot water. Current supplied by the powered anode will kill the bacteria that creates the smell in the hot water. This is the cheapest long-term solution available on the market.
How long does a sacrificial anode last?
It's the same with the different types of anodes. Sacrificial anode will last between 2 to 5 years and powered anode will last up to 50 years. In addition, powered anode rod will give you some benefits that you will never have with sacrificial anode.
What is a sacrificial anode?
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. The sacrificial anode will be consumed in place of the metal it is protecting, ...
Why is it important to check the width, length and thickness of the rod portion?
It is very important to check the width, length and thickness of the rod portion which is covered with MMO to conclude its service life. It is the most expensive part of the anode, which is why some manufacturers reduce the required quantity, which reduces the efficiency and the lifespan of the anode. Power supply quality is also important ...
What is cathodic protection?
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.
Do powered anode rods degrade?
Overall, there are quite a few advantages to using powered anode rods. They don’t degrade, prevent smelly water, and protect your hot water heater from corrosive elements in the water. Since powered anode rods don't degrade like magnesium rod, they are designed to last for a very long time).
What is an anode rod?
What is a Powered Anode Rod? Powered anode rods are non-sacrificial rods (meaning they don’t degrade like a normal anode rod) which use electrical pulses to deal with corrosive elements in your water. These pulses scatter the harmful electrons, preventing them from accumulating along the lining of your tank.
Who makes the best powered anode rods?
Probably the best powered anode rod today is made by Corro-Protec. Their powered anode rod comes in 3 different sizes to perfectly match up with the size of your water heater tank. Other models, such as the more expensive CerAnode expandable rod, can be used to replace both your normal sacrificial anode rod and your hot water outlet rod.
Why use anode rods in water heater?
They don’t degrade, prevent smelly water (by killing anaerobic bacteria that leads to that rotten egg smell ), and protect your hot water heater from corrosive elements ...
Powered Anode Rod vs Sacrificial Anode Rod
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? Let’s find out.
What Does The Anode Rod Do?
All water heaters have a small component called an anode rod. You will hear this essential water heater part referred to as sacrificial. That’s because an anode rod stands between your costly water heater and rust.
How Long Will The Sacrificial Anode Rod Last?
An anode rod will spare your water heater tank the effect of corrosion for roughly 3 to 5 years. How long it lasts is based on the quality of your water supply.
What Do Water Heaters Powered Anode Rod Do?
The water heaters powered anode rod does the same job as the anode rod that comes with your water heater. They keep your water heater tank safe from rust. But they do that job a bit differently.
How Do Powered Anode Rods Work?
We won’t go into the science of it. But these impressed-current anode rods work using small doses of electrical pulses. Those pulses repel the corrosive elements in the water.
How does a magnesium anode rod work?
How Magnesium Anode Rod Works. The magnesium anode rod will sacrifice itself to protect the water heater. Since corrosion always attacks weaker metals first, the magnesium anode will corrode until it is about 50% consumed. After that, the tank will start to rust and will last couple years.
What is the metal with the more negative potential compared to the cathode?
What is Corrosion And How to Stop it. Anode :The anode is the metal with the more negative potential compared to the cathode. Cathode : The cathode is the metal where reduction occurs (gain of electrons). Electrolyte : The electrically conductive medium in which the anode and cathode reside.
How long has Corro Protec been in the lab?
Although the technology has already existed for several decades in the industrial sector, we have been testing Corro-Protec in the laboratory for more than 12 years in order to offer you safe and effective products. It allowed us to determine the components needed to manufacture the anode in order to provide the best possible protection all the while remaining affordable. Corro-Protec use a titanium rod covered with mixed metal oxyde (MMO) made to last over 20 years.
The Anode Rod
An anode rod is a long metal rod, usually formed of magnesium or aluminum around a steel wire core. The rod is inserted into the water heater storage tank, where it slowly degrades. As long as the anode rod is degrading in the tank, the tank lining will be protected from rusting.
Checking the Anode Rod
Eventually, the anode rod will degrade to the point where it can no longer attract the ions that cause rust. At that point, the rod will need to be replaced in order to maintain protection for the water heater tank. A water heater tank with an expended anode rod is no better off than one without an anode rod at all.
