What is hard water limescale?
Calcium and other dissolved minerals occur naturally in our water supply. Water is described as ‘hard’ when it contains higher than average levels of these minerals. If hard water is heated past 55 degrees or left to stand, these dissolved minerals solidify and form a white crust known as limescale.
How does limescale damage appliances?
Limescale can be unsightly on kitchen and bathroom taps and reduces the effectiveness of detergents. However the invisible effects of limescale are far more serious. Limescale coats the heating element in your boiler and other hot water appliances, making them less energy-efficient and more likely to break down.
