Bleeding Radiators squence

[Starship1]

I wonder if anyone can tell me if there is a sequence to bleed radiators, as i have trapped air in the upstairs, At the moment all upstair radiators don't seem to be heating to max, whilst the downstairs are. I have opened the bleed screws to the rads upstairs and the air starts to release, but unlike the downstairs they don't release all the air. Do i have to close valves on other rads then bleed the last in line or ????.
I have a Worcester Combi Boiler with 3 rads down stairs, 3 rads upstairs..

Thanks..

You will need to top the pressure up on boiler

Take a look at that

Take a look at that

Thanks Simon, Hvae the idea, but any additional info as i already seem to have my hose in place, is it just a matter of opening each valve ( see image below).

Just open valves and look at pressure gauge til you hit 1 bar

Best to turn boiler off electrically while you do above and turn back on once all topped up and vented ok :smile:

Thanks guys. Just one question all seems to be ok with the exception when heating the system the pressure bar is showing 2.0 is this exceptable ?. Or do i have to release some pressure.

 

[SimonJohns]

That'll be ok. Have you turned the valves back off properly?

 

[Starship1]

Valves turned completly off.
All rads running nice and hot now. pressure as below.

 

[SimonJohns]

If your heating is on. It's normal for the gauge to rise.

Thankyou Simon, very grateful for your help. just one last question, is there a danger point on the gauge, if so is there a way of releasing pressure, just so i know for the future if called upon.

Pressure releif valve will take care of any pressure over 3 bar

If you did over fill during top up,just get an old towel and let out excess through a vent on a radiator

Thanks All for the help. all is running spot on now.
Happy new Year to you all.
