The municipal waterworks in Glücksburg publishes a test report from the works outlet (dated May 2026). It states 198.1 mg/L CaCO₃, about 11.1 °dH. The sample was taken at the works exit, not at a household tap, and the document does not explain where the water comes from. If you see limescale spots or deposits in a boiler, check the hot water temperature and descaling intervals.
German law (WRMG) uses 3 bands: soft < 8.4 °dH, medium 8.4–14 °dH, hard > 14 °dH.

What it means at home
- Severe scale: heater elements and washing-machine heaters fail early.
- Detergent use is very high; taps and screens coat within days.
- Dishwasher at maximum salt setting.
- An ion-exchange softener is practically essential; RO for drinking water.
How much salt will you use for softening?
Yes. At this hardness a softener pays for itself through appliance life and detergent.
Descale a coffee machine or kettle about every 1 months (typical manufacturer guidance for this hardness).
