Sat here - the rad to my right keeps gurgling and making noises that I
assume is air passing round in it. Yet it's red hot - and when bled -
there's nowt in it. Any air in the system collects in the top of the
tallest rad - and that is the subject of my post earlier this week.
So what the hell is it if it's not air? It's making that gurgling
noise like it should be air - now I'm flummoxed.
if it's red hot then maybe you've got steam! if the boiler temperature is
too high and producing steam in the system them you would get "steam hammer"
in the system making those noises. Can you slightly reduce the boiler water
Q, it's not that hot - but uniformly hot with no cold spots or dead
spots. Very odd.
I can turn the stat down a spot and see if it makes a difference -it's
not even on half now tho! And it's only a small boiler :)

Probably is air, drawn in down the vent pipe by the pump being set to

Air will generally collect in the first rad from the boiler, this may
or may not be highest one.

It doesn't always collect at the highest point - life's not that simple.
If you're not using inhibitor (Fernox) that's worth a try - for some
reason it seems to quieten down this sort of noise. However, if you've
just re-filled the system it should eventually go away if it's not sealed.
