Softening unit or alternative lime protection: When do I use each method?

Both systems protect your drinking water installation from calcification. The most important difference is that the softening unit removes the hardness from the water. The alternative limescale protection system leaves the lime in the water – but ensures that it does not settle in pipes. For this purpose, the device forms microscopical “seed crystals” which flow with the water into your building installation. There, excess lime preferentially settles on these seed crystals – and not in the pipes or on the surface of heating systems.

So if your sole concern is to protect your installation and your appliances, choose the alternative limescale protection.

If you appreciate the comfort, caring effect and better taste of soft water and you want to clean less in your bathroom – then a softener is better choice.
