I have installed a new rad in the bathroom, when I first let the water back into the system the rad bleeds air all the way to the top with pressure then after a few minutes it only feels warm at the bottom and when i try to bleed the rad there is no pressure to push out the air.

Problem solved due to bleeding radaitor's with the pump off.

thanks

you dont say what boiler ie, combi/system.
first thoughs, after you bled rad did you top up the system too 1-1.5bar? (combi or sealed system) .
is the header tank topping up and any valves you closed re-openned (vented system)
