The efficiency of water-softening installations largely depends on the quality of the salt used.
Hard water costs money
Water is more than just H2O. Water also contains various high concentrations of calcium and magnesium ions and this leads to scaling and furring. This will reduce the life and efficiency of heating equipment, pipes and taps. Besides this, hard water also reduces the cleaning power of soaps and detergents and causes unsightly scale on baths and crockery. As a result, water is softened in order to save money and avoid inconvenience.
Water-softening
Water softening installations remove unwanted calcium and magnesium ions by a process referred to as ion exchange
