If you use a water heater with a tank, you should be aware of the fact that there is a component called an” anode” within that tank. You certainly don’t think about it on a daily basis, if at all, but this anode plays a vital role in protecting the tank of the water heater.
What is an Anode and how does it work? Steel is a very useful material. But any material, no matter how sturdy, is eventually going to rust when it's combined with water over a long period of time. We understand this, so we have created lines of defense to help your water heater last longer.
Inside your tank, there is a glass coating this lining prevents water from even coming into contact with the steel of the tank. But even this glass coating may have pores or imperfections that may expose the steel to water.When this occurs, the water within the tank then moves on to the steel that the water heater is composed of. This is when the second line of defense comes in - The Anode.
An anode rod (sometimes called a sacrificial anode) is typically made of Aluminium, magnesium or Zinc and is a crucial component that serves a specific purpose: to protect the metal tank from corrosion. Here's how it works:
Corrosion Protection:
The main material used for water heater tanks is usually steel, which is susceptible to corrosion when it comes into contact with water. Water naturally contains dissolved oxygen and other impurities that can accelerate the corrosion process. When corrosion occurs, it can weaken the tank and lead to leaks or failure of the water heater.
Sacrificial Anode:
To prevent the tank from corroding, a sacrificial anode rod is installed inside the water heater tank. Typically, this rod is made of a more chemically active metal than the steel tank, often magnesium or aluminum. The term "sacrificial" means that this anode rod will corrode preferentially to the steel tank.
Electrochemical Reaction:
When the water heater is in operation, the anode rod undergoes an electrochemical reaction. It releases electrons, which flow to the steel tank, effectively protecting it from corrosion. In this process, the anode rod corrodes over time, gradually sacrificing itself to preserve the integrity of the tank.
Regular Replacement:
Eventually, the anode rod will be depleted, and it will no longer provide effective protection. Therefore, it's essential to inspect and replace the anode rod periodically, typically every 2 years, depending on water quality and usage. This maintenance helps extend the lifespan of the water heater and prevents premature tank failure.
The anode is more reactive to corrosive elements in the water than the tank itself is, so the water will essentially eat away at the rod before moving on to its main course: the tank. When you are diligent in replacing your anode as needed–typically every few years, you may be able to double the lifespan of your tank.
Many factors, such as the water quality in your area will influence the lifespan of an anode, so it should be inspected regularly.
Regular water heater maintenance is a worthwhile investment. We at Venus,strongly recommend that you should at least have your anode checked every few years after your Product Guarantee period of 2 years. If your anode is past a certain point of degradation, then our service technicians can replace it so that your water heater stays in good operational shape.
It is strongly recommended to go through the User manual of your Venus water heater to understand the Terms and Conditions of service.
The User Manual clearly states,
CAUTION
Anode’s protection is important to ensure tank’s life.
Anode maintenance is needed to ensure product guarantee.
If you don’t invest in service for your water heater on a routine basis,
The Company's liability under the guarantee will be limited only to defects which occur under conditions of proper installation, normal operation, and under proper use. It excludes defects occurring because of lack of anode maintenance,
