How long is it acceptable to run the system

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.

Interesting view form a professional.

It's certainly interesting, no question about that.

From my own experience inhibitor is essential if you have steel rads.
Without it you end up with loads of crap in the system.
