One radiator wont heat up

[shaq]

Hi, i have flushed my heating system and put and inhibator in. one radiator now wont heat up,i have tried balancing the system but it feels as though the valve is blocked as there is heat upto the valve in the pipe... only problem is this is a new valve and was working beforehand ( system was flushed as changed a rad in a different room which funnily enough had the same problem. hope someone can help :confused5:

Airlock. Close all other rads bar that one. Should push it through. Failing that, tray under each end and run water from each end with opposite one closed.

Small microbore plastic/copper pipes by any chance? Try as suggested above from SimonG.

Hi by closing all the other rads will push the air out ? does that mean i clsoe all the rads then run the heating and then bleed the rad ?

Yep. ?

As above ... turn all off bar the one not working. If that doesn't clear the issue then you're looking at a restriction in the radiator/radiator circuit or pump flow.
