With the colder weather upon us, the central heating has been switched on
again and it's going to be another month or two before the radiators in
question are reconnected. How long is it acceptable to run the system
without inhibitor in it. If necessary I could put it in this weekend, but if
it's not reeally necessary for a couple of months then I'll wait.

My central heating system is over 30 years old and for the last 6
years (At least) has run without inhibitor. It's possible it's never
had inhibitor in it.

As long as you put the Fernox in next spring I personally wouldn't
worry.
