Kettles
The problem relating to scale can be seen particularly clearly in electric kettles. Such appliances are used to heat water very quickly and strongly. In the case of untreated water, scale is deposited on the walls even after only a short time. This reduces the efficiency of the kettle and more time and energy is required to heat the water.
Under normal conditions , Merus is not able to fully prevent precipitation of the scale either. However, if Merus is used correctly, far less scale is generally produced. If a little cold water is always added to the kettle after boiling, the treated water is able to partially dissolve the scale again. If no satisfactory result is achieved despite the use of Merus, this may be due to the fact that the kettle generates an electrical field which reduces or cancels the effect even when not in operation. You should simply disconnect the mains plug when the kettle is not in use.
