All of the water in my radiator system was drained in March as I needed a new radiator fitting. Due to the nice weather back in that month, I only turned the heating system on 3-4 times more, yet one radiator needing bleeding as a lot of air had got (although I think that after a drain out, one should expect to have to bleed a radiator - is this correct??). Due to the colder weather now the time has come to turn on the central heating system again. If the radiator keeps filling up with air what would happen I was away for a while and unable to bleed it .... would the air eventually fill all of the radiators on the system or just block out the defective radiator and leave the other ones alone?

Let's try guessing:
I think it's an open system with a feed & expansion tank in the loft, full of brown sludge.
I also think he's got a hot-water cylinder
I think he's got a pump by the cylinder and a three-port valve electrically operated with a room stat and a cylinder stat.
The reason for draining was to fit a new radiator, which was a different size to the old one so it wasn't enough to just close the rad valves.
When he took the radiator off the water was clear and there was no black sediment.
I think he lives in a hard-water area.
No chemical cleaner was used to loosen the old sediment so it has probably settled and hardened inside the boiler, which now clonks and gurgles when it is started up.
He's also got an immersion heater in the cylinder which he was using during the summer. His boiler is a 30-year old Potterton Flamingo and it has not been serviced for 6 years.
Who else wants to make a guess?
