Magnesium anode protects heating elements and tank walls from scale formation and corrosion

It can be added here that some models are equipped not with magnesium, but with inert anode rods, which are much more efficient and require frequent replacement. However, this convenience is also reflected in the cost of the boiler.

6. Type of electric heater. You can choose a boiler with a "dry" or "wet" heating element.
