SčVK publishes 219.2 mg/L hardness as CaCO₃ for Vintířov in the Ústí region, a very hard value. The Chomutov area is a mix of volcanic uplands and basin sediments, and the utility page does not name the source for this village, so the cause is unconfirmed. Expect scale on kettles and heaters, and descale them regularly.
Czech suppliers report "Vápník a hořčík" in mmol/L; the recommended range is 2–3.5 mmol/L.

What it means at home

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).
