What problem does Sentinel KalGUARD address?

Almost two thirds of the UK is supplied with ‘hard’ mains water which, when heated, deposits limescale onto internal surfaces of pipework and the heat transfer sufaces of boilers, and other appliances. These deposits compromise the efficiency of water-heating appliances and systems, making them ultimately more expensive to run. Limescale is also unattractive when encrusted onto shower heads and taps and can be unhygienic, providing places for bacteria to hide.
