Novaj, in Heves county, is reported at 242.7 mg/L CaCO₃ in the NNGYK 2024 drinking-water data, which is very hard. Most Hungarian tap water is groundwater, and the report gives one value for the village without a zone split. Appliances that heat water will collect scale over time. Regular descaling helps.
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).
