I'm considering giving one a try on the cold input to a Combi.
However these electronic descalers are advertised to work (or not)
with a magnetic field applied to the water, so - Is there any
problem with them interfering with other systems, e.g. the chip in the
boiler itself, or the thermostat control system which in my case is
wireless??

The chip?
