The Scale Wizard makes a simple solution to limescale removal in hard-water areas.

All of us have hot water systems (cylinders, immersion heaters, combi-boilers, heat exchangers) running somewhere in our homes, and most of us pay the 'workings' little or no attention - until they break down! Over time, however, these workings can be gradually coated in more and more scale.

The Scale Wizard is a device designed to slow down the amount of scale build-up on such systems; this is an electronic water conditioner designed to control hard water scale using a patented, modulated, electronic signal system that changes the calcium structure and prevents it from forming hard-water scale.

Scale Wizard comes from an innovative company of twenty years standing which has invested in solutions that offer real benefits for consumers around the home and sells directly to the public.
