Causes of Limescale Problems
Heating systems such as hot-water boilers and kettles always develop a hard and chalky deposit on their heating surfaces. This deposit is referred to as Limescale, and is formed by calcium carbonate present in the water. The amount of deposition is normally directly proportional to the concentration of the calcium carbonate.
The direct effects of Limescale problems include; damage to the system’s components and general reduction in operation levels. Heating systems should therefore be well maintained to prevent this deposition. You can find further information at the Water Guide website
