A Deep Dive: The Science Behind What Makes S.O.S. Protect Special

Water heaters are integral to both residential and commercial properties, providing hot water for everything from cooking and cleaning to heating and sanitation. However, over time, one of the greatest challenges faced by water heaters is corrosion.

While traditional anode rods can help prevent this problem to some extent, S.O.S. PROTECT ® powered anodes are revolutionizing how we protect water heater tanks. But how do they work? Let’s take a closer look at the science behind powered anodes and how they offer enhanced protection to your water heating system.

What are Powered Anodes?

Unlike passive anode rods, powered anodes use a modulated electrical current to actively stop the corrosion of the tank. This is accomplished by constantly checking the electrochemical landscape inside of the tank to make sure that there is no possibility for corrosive phenomena to take place. 

Essentially, a powered anode generates a controlled electrical current that works to impose a “cathodic protection” on the steel tank, which helps neutralize the corrosive effects of water in the tank. The result is a more consistent, long-lasting method of preventing corrosion compared to the passive and maintenance demanding protection offered by traditional anode rods.

The Science Behind Cathodic Corrosion Protection

To understand how S.O.S. PROTECT ® powered anodes work, we need to delve deeper into the principle of cathodic corrosion protection. This is the same science used to protect metal structures such as pipelines and ships from corrosion. In a traditional, non-powered water heater, the metal tank naturally becomes the anode (the part that is corroding) and the anode rod becomes the cathode (the part being protected). Corrosion occurs when the tank’s steel is exposed to the water, and electrochemical reactions occur at the surface of the metal. These reactions are driven by the electrical difference between the tank and the anode rod. Iron that is in contact with oxygen rich water will always want to go into solution and then turn to iron oxide. This is the process of corrosion. In a traditional water heater using a sacrificial anode, the anode will corrode instead, supplying a current to the tank. The generated current will change the electrochemical landscape at the tank, turning it to the cathode, stopping any corrosion phenomena. This can only happen as long as the sacrificial anode is not used up. When a S.O.S. PROTECT ® powered anode is introduced, it also supplies a small electrical current to the tank, turning it into the cathode and reversing the natural process of corrosion. The powered anode acts as a “supercharged” version of the traditional rod, continuously providing perfect protection for the tank without being used up.

The Key Mechanisms of S.O.S. PROTECT ® Powered Anodes

  • Electrochemical Protection: At its core, the S.O.S. powered anode applies a constant, low-voltage electrical charge to the tank, which inhibits the electrochemical reactions that lead to corrosion. It essentially reverses the corrosion process by ensuring that the tank is always maintained as a cathode, making it impossible for corrosive elements in the water to attack the steel.
  • Enhanced Control of the Protection Process: S.O.S. powered anodes give you more precise control over the corrosion protection system. While traditional anode rods are reactive and need to be replaced when worn down, S.O.S. powered anodes are actively working 24/7 to protect the tank. The electrical charge can be adjusted based on the water quality and tank size, optimizing corrosion prevention for each specific system.
  • Continuous Protection: Without the Need for Frequent Replacement One of the most notable advantages of S.O.S. PROTECT ® powered anodes is their longevity. Traditional anode rods degrade over time and must be replaced every few years. S.O.S. powered anodes, however, are designed to last much longer. The electrical current helps extend the life of the system by preventing wear on the anode itself, resulting in significantly reduced maintenance costs.
  • Adaptability to Water Quality Conditions: Not all water is created equal. In areas with hard water, high mineral content, or aggressive water chemistry, corrosion happens more quickly. S.O.S. powered anodes will adapt to meet the needs of varying water conditions. The system can adjust the electrical output based on the mineral concentration in the water, offering more effective corrosion control in challenging environments.
