Isn't an Aqua dial a conventional ion exchange unit?
They do work as we all know.

Its the electronic descallers that don't which it waht the OP asked about.


Descalers are not water softeners.

Descalers only claim to prevent hard scale build up in certain places.

They are supposed to modify the type of crystals that are produced so
that instead of scale constipation, you get carbonate diahoerrhea.

This - if it works* - may well protect central heating pumps, and even
stop appliances scaling up, but it does nothing for soap consumption and
will still leave calcium stearate scums everywhere on the bath.

*and even the most positive tests seem to indicate it only works close
to the device in areas of cavitation like pumps.
