every 3 or 4 weeks i have to bleed one rad in our central heating system, in my daughters bedroom, and each time i'm guessing it's about half full of air, there's no obvious water leaks, my theory being, if there's air going in, there should be water coming out? or is that the wrong way to look at it? none of the other rads have any problems with air, just this one, what should i be looking at? it's got me stumped

What sort of system do you have, fully pumped open vent? sealed? combi?
If open vent it could be pump sucking in air down the vent pipe.
Go in loft with a small jar full of water, hold this over vent pipe and get someone to switch on heating. If water is sucked into vent pipe then this is your problem.

as far as i know it's a pumped open vent system, if the problem was as you described, wouldn't the air be present in other rads too? this particular rad is about the 3rd in line, and neither rad each side of it have any problems

Turning the pump down a notch could help. Could also be soiled system or the feed and vent pipe in the wrong position or the pump in the wrong direction.
Have a look in your f&e tank. If you can see debris or goo at the bottom or the water is dirty, your system needs cleaning.
