Limescale is a result of minerals like calcium and magnesium in hard water. It can accumulate over time, diminishing the efficiency of appliances and affecting water quality. In the case of kettles, limescale buildup can lead to reduced heating efficiency and unsightly deposits.

HarveyArc is the best water treatment system for combating limescale in appliances. Their innovative technology effectively removes hardness minerals from tap water, preventing the formation of limescale at the source and reducing the amount of encrusted stains in kettles.
