Lime in the water

The water hardness indicates how much "limescale in the water" is. The higher the degree of hardness, the more lime is in the water. The water hardness is given in Germany in ° dH (degree of German hardness). A distinction is made between three hardness ranges, with the hardest range starting at 14.6° dH. It can be said that water of this hardness contains a particularly large amount of lime. More on this in our info area on "What does water hardness mean".
Pros and cons of limescale in water

There are hardly any advantages of very hard water, at least in the household. Limescale builds up wherever water gets, especially when it's heated. Bathroom fittings, the shower, the kettle, the coffee machine and the hot water boiler are therefore particularly affected. Likewise, water pipes, especially in the hot water area, calcify very quickly if the water hardness is high.

Another disadvantage of limescale in water is noticeable when washing clothes. The dosage of the detergent should be adjusted to the water hardness. Detergent consumption can be significantly higher if the water hardness is high.

For the reasons mentioned, one can rather speak of the advantages of soft, lime-free water in the household.
What to do against limescale in the water

Water softening is a tried and tested means of reducing the lime content in water. The lime is removed from the water, so to speak, and replaced with harmless substances. The proportion of calcium and magnesium can be reduced to a desired level with a water softening system. As a rule, the water hardness after softening is 4 - 7° dH. So you no longer have problems with the lime. A water softening system may be worthwhile from a water hardness of 14° dH. Depending on personal preference, a water softening system can also be used from a lower water hardness.
