The figure of 114.2 mg/L CaCO₃ comes from one detailed analysis of the Wurzelbach supply (WVG 1), taken on 20 April 2026, and falls in the soft band. The utility's document does not say that this works supplies the whole town, so other districts may differ. Soft water means slow scale build-up, though the sample alone cannot show seasonal changes.
German law (WRMG) uses 3 bands: soft < 8.4 °dH, medium 8.4–14 °dH, hard > 14 °dH.

What it means at home
- Visible kettle scale every few weeks; vinegar or citric acid is enough.
- Water heater and washing machine: some long-term scale; a scale inhibitor slows it.
- Dishwasher: medium salt setting.
- Softener optional; pays off mainly with a gas boiler or tankless heater.
How much salt will you use for softening?
Optional. A scale inhibitor or a small softener protects the heater; soap savings are modest.
Descale a coffee machine or kettle about every 3 months (typical manufacturer guidance for this hardness).
