How long is it acceptable to run the system
without inhibitor in it.

I had always used Fernox .... when I had my new system commissioned, my
CORGI man (been in business 30+ yrs) told me he NEVER adds inhibitor, it is
not needed and just a marketing ploy.

Well, that voids the manufacturers' warantees on most new boilers.
Does he offer his own warantee instead?

Interesting view form a professional.

Not really.
