Matt, again..."If the system is not re-dosed, and 95% are not, then
the
Magnaclean prevents blockages". Got it?

The same ignorance that would cause people not to replenish their
inhibitor
will predicate against the use of an expensive alternative.

If it is fitted on a boiler change or new installation then it is
there,
even when the house changes hands and the new owners are ignorant of
inhibitor. How many service engineers replace inhibitor? How many
bother to check if it has been replaced?


Given that in reality inhibitor should
last many years despite what it recommends on labels, the statistics
you
quote bear little resemblance to reality.

I haven't quoted ant stats.

Yes you have. You said that 95% are not. Where is your source for
this statistic?

Me. I know these things.
