Hard water is water that contains dissolved minerals such as magnesium, iron and manganese, and most often calcium. Water naturally becomes hard as it moves over and through the earth to either a reservoir or into an underground aquifer. Hard water is probably the most common water problem found in municipal and well water supplies. Hard water can cause what is known as scale (normally calcium carbonate, or limescale as it is more commonly known) to build up inside appliances and equipment that utilise water, but particularly ones that heat the water such as boilers, dishwashers, washing machines, cooling systems etc. This can have a significant impact on energy consumption and efficiency.
