When there is no inhibitor in a system, the slightly acidic water causes galvanic corrosion to occur between the copper pipes, brass fittings and the steel radiators. Without getting too technical, there is an electrical cell generated which causes hydrogen gas to be formed, this gathers at some point, and you have to let this "air" out. The result of this corrosion is eaten-away radiators, black water formed , and expensive replacement of rads.
Surprisingly it is easily prevented by "FERNOX' cost about £15 and protects for years
The reason heating engineers don't put it in is rather simple, as it gives them continuing work in 8 years time !!!
You could call it built-in obsolescence.

Finally,, someone that knows what they are talking about and not just here trying to get points ... Listen to Xenon,, here is a site for you to go to and read about Fernox.

Next time you vent , see if you can light the air (GAS/AIR) with a lighter,, if it lights , it is from corrosion in your system and you need to install some chemicals to offset this problem. Call a licensed heating contractor to solve your problem.

when you bled it you have to top up the cistern you should find a tap next to your main boiler so even though you let some air out unless you replace it with water you will still have air i hope this makes sense to you

I had the samwe problem, it turned out to be an air lock. I had to get someone in to do it for me.

check the pressure of your boiler it might be low
