The 2024 NNGYK data put Nyírkércs, in Szabolcs-Szatmár-Bereg county, at 295.4 mg/L as CaCO₃. That is very hard water. The report does not describe the supply source, so no claim is made about it here. A softener or scale-reducing filter is worth considering for a water heater.
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).
