Just had a leaflet for this gadget, Scalewatcher, put through the door. It
claims to prevent new scale forming in the water pipes and reduce what is
there. Appears to be a small unit with wires wrapped around the pipe and
costing around £3 per year to run. I have a vague feeling that I heard of
similar gadgets years ago. Has anyone any knowledge of this kit and is it
worth pursuing (gut feeling says not)? They don't mention the price
either, any idea what that would be?
You will now predictably get a few replies from others stating that they are
'snake oil' and any proof that they work is fabricated.
I installed one a few years ago and the scale formation in my kettle was
reduced quite a bit over a period of time and I imagine my boiler too -
however - with my electric shower, instead of the scale forming and
gradually killing the heater can & element, the scale partially formed on
the element and was then ejected in tiny bits which were perfect for
blocking the shower head even straight after cleaning it out.
My opinion is that they do slow the formation of scale to a certain degree
but this is only beneficial in certain circumstances.
Whoa! we got a device that sounds exactly like that I think we paid about
ten quid for it in a local DIY store. It's a small box full of electronics
with a row of green and red LEDs which indicate if it's working OK (all
green is OK if any red one light, you should turn it off then back on to
reset), then you have two lengths of thin wire, one from each end of the
device and about 3ft long. You mount the device on a pipe as close to the
main water inlet pipe to the house as you can, then wrap each length of wire
around the pipe either side of the device - I assume forming some kind of
electro magnetic field?? not that calcium is magnetic!
Anyway, we've had this....must be 20 years and all I can say is, if it
works, then I'd hate to see the state of my kettle if this wasn't
connected! - how do you judge? How does it work?
