    Hard water is water which has dissolved minerals in it, specifically Calcium and Magnesium. Hard water provides a good source of these minerals and is good for you to drink, but when boiled it leaves mineral deposits (limescale) and when surfactants (detergents) are added to the water then do not foam properly. Solutions to this are the use of ion replacement (replacing calcium and magnesium with sodium) or magnetic treatments.

    disadvantages - generally waste of time, energy and money
    When hard water is heated, the carbonates precipitate out of solution, forming scale in pipes etc. They clog and narrow pipes, scale prevents efficient heat transfer, so a water heater with scale will have to use a lot of energy to give you hot water. Soap is less effective in hard water because its reacts to form calcium or magnesium compounds

    advantages - some say it tastes better, Ca and Mg good for you (suposedly for those prone to heart attacks- and Ca is good for bones and teeth)

    hope thats helped a bit

    I really don't like the water up preston way for some strange reason, in fact I can't actually drink it.

    Hard water I have no problem with, flouridated and water treated with chlorine however.... Im probably just spoiled from scandinavia where they pretty much use Ozon everywhere, but I don't like the taste of halogens in my water...
