Kelemér in Borsod-Abaúj-Zemplén county is reported at 506.9 mg/L in the NNGYK 2024 survey, which is very hard and among the highest values in this batch. The survey does not give the water source, so the cause is not confirmed here. Scale will form quickly on heating elements, and a softener is worth considering.
Hungarian suppliers report total hardness in German degrees (nk°) or mg/L CaO; the limit is 50–350 mg/L CaO.
