Hidegség in Győr-Moson-Sopron is listed at 364.1 mg/L CaCO₃ in NNGYK's 2024 water-quality data, a very hard value. We have not confirmed which waterworks feeds the village. Scale buildup on heating elements and glassware is the likely consequence.
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).
