Stadtwerke Weiden's 2026 analysis gives a calculated hardness of 153.5 mg/L CaCO₃ (8.6 °dH, 1.54 mmol/L), in the utility's medium band. The method is computed from the measured minerals rather than read directly. The utility's own page states 8 to 9 °dH, which agrees. Weiden is in the Upper Palatinate, where the crystalline bedrock tends to give softer water, but the analysis does not name the source.
German law (WRMG) uses 3 bands: soft < 8.4 °dH, medium 8.4–14 °dH, hard > 14 °dH.

What it means at home
- Fast scale on taps, shower screens and kettle; white spots on glassware.
- Water heater: efficiency loss and element failures within years if unprotected.
- Dry skin and dull hair after showering are common.
- Softener recommended; jug or reverse osmosis for drinking.
How much salt will you use for softening?
Recommended, especially with a heater or boiler: scale cuts efficiency and shortens its life.
Descale a coffee machine or kettle about every 2 months (typical manufacturer guidance for this hardness).
