Can limescale build up on a powered anode rod?

Published and updated

Our response

Limescale may form if the anode is too close to the walls of the hot water tank and the current flows too quickly between the anode rod and the tank. Corro-Protec powered anode, unlike other anodes, has a design that prevents this type of reaction. Indeed, the white plastic present in the top of the titanium anode prevents this kind of reaction and ensures that the anode is well positioned in the tank.
