My system is still playing up. The only way I can get all radiators to
now work is to close them all and then open then one by one. However,
whilst doing this I am bleeding each radiator and NO air is coming out
- I havent a clue where this airlock is. I have also advanced the pump
speed from 1 up to 2 in an effort to apply more pressure to the system
and force the air around to *somewhere*. Im stabbing in the dark to be
honest so any suggestions are more than welcome.

A suggestion I saw on here a couple of weeks ago, which worked for me
just before Christmas....

Close off all but one radiator. Bleed a substantial amount of water
(about a pint) from that one. Turn the system on and wind the pump up to
maximum speed. Repeat in turn for other radiators. This finally fixed an
airlock I'd been chasing for weeks.
