Halastó, in Vas county, shows 75.0 mg/L CaCO₃ in the 2024 NNGYK dataset (HUMVI), which counts as moderate. That is lower than the very hard readings common elsewhere in Hungary. The local water source is not stated, so we do not name it. Limescale should be mild.
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
- Visible kettle scale every few weeks; vinegar or citric acid is enough.
- Water heater and washing machine: some long-term scale; a scale inhibitor slows it.
- Dishwasher: medium salt setting.
- Softener optional; pays off mainly with a gas boiler or tankless heater.
How much salt will you use for softening?
Optional. A scale inhibitor or a small softener protects the heater; soap savings are modest.
Descale a coffee machine or kettle about every 3 months (typical manufacturer guidance for this hardness).
