What is a magnesium anode, what is it for, and how often do they need to be changed?
The anode is a very important part, which is installed by the factory in each boiler. The anode works without connecting any wires, it is located near the heating element and plays the role (lightning rod).

During operation of the heating element in boilers, electric boilers and other household appliances. (at the moment of sharp water heating, heated streams quickly rise up, when cold streams go down, there is a constant movement of water and bubbles such a movement (like clouds at the time of a thunderstorm) form energetically charged particles.) a stray current is created, it is like a micro lightning is looking for a more convenient place to hit the body, since the body is the ground for this process.
The anode just serves as this (receiver) of the strike, (lightning rod) since it consists of a variety of conductive alloys (magnesium, aluminum, zinc, etc.), taking the blow, the anode transfers currents through its body to the tank body, itself is slowly destroyed.
In boilers, the anode is usually installed directly in the heating element, in some boilers, it is installed on top of the tank, in a special place, and in some it is completely hidden so that not every master can find it. The main reason for the breakdown of heating elements is the destruction of the anode.
After the decomposition of the magnesium alloy, the stray current continues to break through for some time into the remains of the threaded connection (anode studs), but it quickly oxidizes and the current finds a more pleasant place, usually the shell of the heating element, the discharge clings to one place and continues to discharge, turning the shell of the heating element into (rusty foil ) at this point, micro holes appear, through which water passes into the middle of the heating element, the boiler gradually begins to beat with current, while the heating element continues to heat up, the water that has entered the heating element begins to evaporate, but it cannot quickly exit through the micro holes, it turns into steam and breaks the ten.
Therefore, some boilers are equipped with protection against electric shock (ouzo)

which cuts down power at the slightest hint of a leak.
Many are interested in the question, which heating elements will last longer without an anode, copper or stainless? for 20 years of work in this direction, we have come to the conclusion that copper heating elements are more durable, but do not think that you can put them without an anode and they will work, this is not so, copper will only last for some time longer, because due to good current conductivity, the discharge does not cling to one place, but walks mainly over the entire surface, gradually biting the shell of the heating element.
The branded anode is made from a quality alloy and the pin is cast deep into the anode itself, which increases its life.
The branded anode has a granular composition and a regular, even slot in the end.
