This figure is over 3 years old; hardness may have changed.
Ramada is listed in zone LO1 of SIMAR Loures-Odivelas. The only LO1 report we could use is from Q4 2022: 65 to 85 mg/L CaCO₃ across 3 analyses, and the 75 mg/L shown is the midpoint. It is old and covers the whole zone, not Ramada alone. A newer SIMAR report would replace it. Moderate hardness means light scale.
Portuguese operators report "dureza total" in mg/L CaCO₃ to ERSAR.

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).
