hard water

Hard water is water that has high mineral content (in contrast with "soft water"). Hard water is formed when water percolates through deposits of limestone, chalk or gypsum which are largely made up of calcium and magnesium carbonates, bicarbonates and sulfates.
Hard drinking water may have moderate health benefits. It can pose critical problems in industrial settings, where water hardness is monitored to avoid costly breakdowns in boilers, cooling towers, and other equipment that handles water. In domestic settings, hard water is often indicated by a lack of foam formation when soap is agitated in water, and by the formation of limescale in kettles and water heaters. Wherever water hardness is a concern, water softening is commonly used to reduce hard water's adverse effects.

    Compact format water softener

A colossal waste of time. Not to mention the...

    I have just had to replace a Wickes electic shower; the new one is a Mira Sprint multifit.

My water is rated a Very Hard, so I guess it's...

    Eddy Electronic Water Descaler - does it work in hard water area?

    I've been looking at water softeners/descalers as there is too much limescale everywhere in my flat (hard water area in London).

    Electrolytic scale reducer versus polyphosphate in hard water areas

    Does anyone have a experience with electrolytic scale reducers in hard water areas (400ppm) versus polyphosphate (Combiguard)? I like the idea of the SESI as it's basically a fit and forget (10-15 years) and there's also no annual maintenance cost.
