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.

AIUI, it depends on the composition of your tap water. You *may* get away
without inhibitor, but it's always *safest* to use it.

To the OP: Is yours a vented system? If so, can't you save the water and put
it back into the header tank so as not to lose the inhibitor? That's what I
do.
