Any opinions on this thing? They claim to have sold 100,000 of them.
Here is Ian S's original description of the device:
----------
Hi folks, at my daughters new home today, installing odds & ends & she
asked me to install an "Electronic scale remover". Being a skeptical
person, I had a look at this device ($500.00) & decided not to instal
it until I knew more about it. Hopeing that someone reading this will
be able to prove me wrong & tell me that it really does work. It is
supposed to remove scale & prevent it's reformation in pipes, valves,
plumbing, hot water systems etc. It consists of a plastic box,
plug-pack (Wall Wart?) & some hook up wire to wind around a water
pipe. The wire is wound around a water pipe for 25 turns, then along
the pipe for 100 to 150 mm (4" to 6") then another 25 turns in the
same direction then back to the unit. The plug pack is 12 Vdc @ 500
mA. The box has a well made p.c.b. with a voltage reg. a couple of
LM358N's 2 transistors & a 16 pin I.C. that has had the type No.
removed by abrasive paper & some passive components. Having 2 coils of
wire wrapped around the pipe would seem to me to be using some form of
magnetic field, but the instructions say "Applicable to all pipes,
Copper, Ferrous & Polymer pipes" I would have thought that with the
power levels available, there wouldn't be much of a field inside a
ferrous pipe.
