HARD WATRT
As so common problem for millions of households across the country.Hard water means excessive dissolved minerals, specifically calcium and magnesium in tap water various in different countries.
Hard water is a negative impact because of much limescale it brings, Thus, in water heaters the heated hard water forms a scale of limescale deposits on the tank surface and reduces the heat conductivity of heaters sometimes even leading to its breakdown. and this contributes to inefficiency and costly electricity bill . Limescale has been known to increase energy bills by up to 25%.
