What is the function of the magnesium rod of the water heater?

At first I thought that the magnesium rod was used for heating, but later I realized that it was not. It turns out that water heaters use heating pipes for heating. The real function of the magnesium rod is to protect the inner bladder.

In order to better prevent the inner tank from being corroded, it is necessary to find a substitute to absorb the scale. Then the magnesium rod is a good choice. The metallicity of magnesium is more active. When the water in the inner tank heats up, after a chemical reaction, the magnesium dissolves in the water. After a long time of use, the magnesium rod will become thinner and thinner, and finally "disappear".

You don't have to worry about whether the magnesium element dissolved in the water is harmful or not. Magnesium is physiologically non-toxic. Therefore, if you use a storage-type electric water heater to take a bath, you can use it with confidence.

Magnesium rods should be replaced regularly

It should be noted that the magnesium rod should be replaced regularly, if the magnesium rod in the water heater does "disappear". It is easy to affect the inner tank in the later stage, and it is also easy to cause leakage.

Under normal circumstances, it takes 1-2 years to check and replace it. When removing and replacing the magnesium rod, you can also clean the electric water heater by the way.
