Help !!! 1 cold radiator

[AFCWhacker]

Help me please before the wife throws me out. We have 1 problem radiator downstairs (front room), that just does not heat up. We had a new boiler fitted last year and all the other rads in the house seem fine. I have drained the entire system, removed and flushed out the rad, poured in cleaner, checked that the pin is out etc. but no joy. Both pipes to the radiator are cold unless I bleed through and drain off water but then the pipe gradually loses all it's heat again.
Being a non plumber I am now at a loss of what to do know ... any help or advice would be greatly recieved before the real cold weather comes in,
Thanks in advance....

try turning off all other rads and see if the pump pushes through to it.

Check it's been piped correctly to

Seemed to work okay prior to the new boiler installation so I'll try that, If it does work what do I do then .... thanks for the advice by the way.

Worked a treat and the front room rad was red hot when I knocked the others off. Gradually opened the others and in a short space of time the heat had completely gone again, put the system on again this morning and the front room rad was stone cold again ... do I have to sacrafice a number of rads to have the other one working all the time or is there anything else that I can do .. thanks for the help again..

Any advice anyone

sounds like system is not balanced correctly

could also be too much 15mm pipe to that rad especially. air getting in constantly...?

Turn the working radiators lockshield valve fully off, then open only 3/4 to 1 full turn.
This will restrict the flow through these, and allow the faulty rad to be fed.
