Are there other ways to protect yourself from lime besides a softening unit?

Yes, there are alternative limescale protection systems that work with an electric current. These systems form microscopic seed crystals from the lime in the water. There, excess lime preferentially settles on these seed crystals and not on pipe surfaces or heating devices. If the water hardness changes, the device adjusts its settings fully automatically.

Calcium and magnesium minerals stay in the water. Pipe installations and boilers are, nevertheless, optimally protected against limescale damage up to 80 °C. Apart from a low electrical energy consumption, you do not need any other materials – even changing cartridges is not necessary.

Please note: These devices don’t soften the water, as do systems that work on the principle of ion exchange. This means that you won’t not enjoy the comfort that soft water offers.
