Terpes (Heves) has a reported hardness of 154.4 mg/L as CaCO₃ in the 2024 NNGYK data, in the hard category. That is lower than several neighbouring villages in the same dataset. The report does not name the source, so we do not explain the difference. Some scale is likely in kettles, but it should be less severe than at the very hard end.
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
- Fast scale on taps, shower screens and kettle; white spots on glassware.
- Water heater: efficiency loss and element failures within years if unprotected.
- Dry skin and dull hair after showering are common.
- Softener recommended; jug or reverse osmosis for drinking.
How much salt will you use for softening?
Recommended, especially with a heater or boiler: scale cuts efficiency and shortens its life.
Descale a coffee machine or kettle about every 2 months (typical manufacturer guidance for this hardness).
