Depending on whether you want to get rid of limescale in the long term or at least reduce its negative effects, there are two different methods.
A water softener is the right solution if the limescale content in the water is to be permanently reduced.
Limescale protection devices form tiny crystals of calcium carbonate from some of the limescale dissolved in the water, which in turn bind the remaining limescale to themselves. This prevents the limescale from settling in the pipes or boilers. The ideal solution for everyone who wants to leave valuable minerals in the drinking water and still enjoy safe limescale protection.
