Reports may cover only some parameters, so values shown may come from different samples. A « < » indicates a detection limit, not an exact concentration. Extraction checks are automated; they do not establish overall drinking-water compliance.

Hard water isn't dangerous. It's just demanding.
Hardness measures the calcium and magnesium in water. At 32°fH, Kehlen is above the comfort threshold (12°fH) — limescale builds up and shows in daily life.
Appliances
Limescale builds up in the water heater, washing machine and dishwasher, shortening their lifespan.
Fixtures
White deposits on taps, shower heads and glass — endless cleaning.
Soap & laundry
Soap lathers poorly, laundry comes out rougher, you need more product.
Taste & feel
Limescale shows in coffee, on skin and hair after showering.
Your water every day
Understand limescale at household level.
Select your home type and household size to explore the annual estimates associated with your local water hardness.
Your annual estimate
Potential limescale removed and estimated savings.
The calculation changes with local hardness and the selected household size. It uses a reference consumption of 135 litres per person per day.
Water heater and water-heating appliances
Soap, shampoo, laundry and detergents
Descaling products and routine cleaning
Wear, service calls and equipment life
Indicative estimate. The limescale figure is the CaCO₃ equivalent contained in the water used. Savings are shown as a range.
Frequently asked questions — water in Kehlen
Is the tap water in Kehlen drinkable?
Consult your municipality’s current analysis report for your supply zone or locality. Water hardness describes limescale and is not sufficient to establish the water’s compliance with health requirements.
Is the 32°fH value exact for my tap?
It's the official network value for your zone. The hardness at your tap may vary slightly depending on network blending and your building's plumbing.
