The latest and easiest system to install and maintain is something called the Water-King 1, produced by Lifescience Products Ltd, in Oxfordshire, at a cost of £129.75 ($299cdn). Instead of chemicals or magnetism, the Water-King 1 (also available are models 2 and 3 for larger premises) uses low-frequency radio waves to change the chemical structure of water - and softens it.
The Water-King 1 consists of a small plastic box that contains a microchip and two wire "aerials" that are wrapped around the mains inlet. It is then plugged into a 12-volt power supply and left alone. It is child's play to install and takes about 10 minutes. Running costs are about £2.00 a year.
Gavin Beaumont, of Lifescience Products Ltd, said: "The whole ethos of the company is to treat the probelms in life with low frequencies and radio waves instead of the more invasive things like salts."
It may sound a bit New Age - but I like the idea of the stuff I drink and wash with not coming into contact with any additional salt or chemicals or with some kind of filtration system. Each Water King 1 is sold with a five-year warranty.
I have fitted one to the water supply entering my cellar. It is too early to see any real effect yet, but apparently the low-frequency radio waves are altering the ionic structure of the water.
They are actually making it ionically "impure" and therby halting the precipitation of limescale. Instead, the crystals form into white, chalky, translucent dust, which is easily swept along with the flow of water.
"The existing limescale or marble, the hard deposits on anything warm or hot, start to break down and take this new amorphous form of crystal. It loosens up and after a few weeks it can easily be picked off," claims Beaumont.
