Balatonbozsok (Fejér county) is listed at 220.4 mg/L CaCO3 in the NNGYK 2024 report, which is very hard. Being near Lake Balaton does not tell us the source, and we have not verified it. Hungarian tap water is mostly groundwater. Scale on kettles and shower fittings is likely.
Hungarian suppliers report total hardness in German degrees (nk°) or mg/L CaO; the limit is 50–350 mg/L CaO.

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).
