Hard water and Limescale |
Hard water in simple terms is caused by rainwater
passing through chalk and/or limestone, where it collects deposits of mineral
salts. The principal salt contributing to hard water is calcium bicarbonate .
The calcium bicarbonate is in a solution form, but precipitates out into calcium
carbonate,which is a sub-microscopic, insoluble molecule. The molecules are attracted
to each other, and adhere to the wall of pipes, etc, creating limescale deposits.
To get a mental picture of this process, simply bring to mind the stalagmites
and stalactites found in caves. The calcium carbonate content of limescale exceeds
98%, therefore if the sub- microscopic molecules can be made to reject instead
of attract, limescale cannot form.
The higher the temperature, the more limescale will form. Therefore limescale
build-up will be greater in the hot water system, particularly immersion heaters
and boilers.
Limescale in your water heating system translates into lower heat transfer. Heating
your water through limescale takes longer, this means your water heating costs
will keep rising as the scale increases. Limescale build-up also dramatically
reduces the life and increases maintenance costs of appliances such as, washing
machines, dishwashers and your water heating system. Combination boilers are particularly
susceptible to limescale as well as the problems above, it can cause poor hot
water flow and noise/kettleing within the boiler - it is strongly recommended
in hard water areas that a scale inhibitor be fitted.
Most of us are familiar with the problems related to hard water, however there
is also a plus side. It is now medically accepted that hard water reduces the
risk of heart disease, and the high calcium content is also beneficial for healthy
bones and teeth, particularly in growing chitdren. |
Scale Manager II does not alter the chemical composition of your water; therefore
the health benefits of consuming hard water are retained. |

Scale Manager II
The world's best electronic water descaler - to treat all types of hard water
in all domestic situations
Scale Manager II is the maintenance free solution to hard water problems,
it will remove existing limescale and prevent further build up without the need
for chemicals, salt, alteration to
the plumbing or a separate drinking water supply. Scale Manager II does not
alter
the chemical composition, but does achieve the advantages of a limescale free
home. |
