Heating - airlock?

[chris-red]

Long story short:- I replaced a rubber seal in the divertor valve in my combi this requried draining the first floor rads. After I replaced the seal I filled and bled the system. Now we have 1.5 bar in the system and no air coming out any rads when I bleed it. All heat up except one not even the pipe before the TRV is stone cold. There is also gurgling when the heating starts. I'm guessing there is air in it somewhere how can I purge it?

Close all the radiators on the system apart from the affected one, which will divert the whole boiler output it and hopefully clear it

What floor is the boiler on and how did you bleed the system?

[Nobby the Bastard]

Have you refilled your system with water? At least one Worcester combi boiler has a sealed system that you have to refill by putting a key in and then turning on the water knob inside the boiler.

Yes it was refilled with water. The boiler is on the ground floor. To refill it I turned on the isolators to allow filling and put 2 bar in the system. I then went round all the rads opening the bleed valves until air stopped coming out I then pressurised the system again to 2 bar and bled out more air until I went round all of them with no air escaping. I topped the system up to 1.5bar

I just tried having the heating running with all other rads off (except bathroom) and no joy I had hear gurgling from the rad but whenever I bleed it water comes out.

Gonna try turning the others on one by one to see if anything moves.

Chris , does the offending rad have a thermostat on it ?


If so take the top of and wiggle the pin and give it a tap , don't go to mad .

I take it it worked before the system was drained. ?
