At this level limescale builds up slowly but steadily. White traces appear on faucets and shower glass within months, and the water heater loses a little efficiency every year. Light protection already pays off.
What it does to your home
Water heater: even a thin layer of scale insulates the heating element and drives energy use up.
Appliances: dishwashers, washing machines and coffee makers scale up and fail years early.
Fixtures and skin: white spots on faucets and glass, dry skin and dull hair after every shower.
