Er... move upstairs 'til Monday? An extra jumper would be good too. I think you'll need some help, I can't see why it's not working.

Drain system, open rad bleed valves so they also empty.

Now go round and close ALL the rad valves - ie both ends.

fill system and bleed each rad in turn as follows. Work from radiators closest to boiler to more distant ones.

Open ONE valve on ONE radiator. Bleed this one until you think rad is about half full. Stop. Close that valve and open other valve continue bleeding rad then close open valve.

Move onto next radiator and repeat.

The theory?? When you refill system the water will enter rad via easiest route. If you have an airlock in the pipe you can easily bleed the air from the radiator using water entering via non airlocked end. By bleeding in above way water is FORCED to flow through BOTH pipes.

I have found this method to work 99 times out of 100 where I have encountered airlock problems in heating systems. For the odd occasion I have other methods. I can ALWAYS remove airlocks from a heating system without too much problem.

Lets know if above works.
