my radiator in my bedroom (1 floor up from boiler) is playing up, its only half full, the bottom gets hot so i tried to bleed it, air comes out of the bleed valve for a couple of seconds but then nothing else does (like water) and the issue remains.
tried it hot and cold.
ideas?

1. Turn the pump off.
2. Check your roof tank level, if that is not full you will mot drive out the air.
3. Check the valves are open on your radiators.
4. start at the nearest point to the boiler
do not forget the domestic cylinder.
5. If there is a lot of air or hydrogen in a particular rad, you will not always get it out in one go.
6. Check the water treatment level after a full bleed and restore rad valve settings.
check it again after a week.

Make sure ther is enough water pressure on the boiler before you bleed the rad. When no water comes out when you are bleeding it is an indication that the water in the system is low. Water pressure should be between 1 bar and 1 and a half

When bleeding rads, remember that as you release air from the system, the system pressure drops. To get the system back up to pressure, you need to re-fill with water. Find your filling loop (probably a flexi fitting with tap), connecting your heating to mains water. Turn on the filling loop until system is back up to recommended pressure (check individual boiler instructions for said pressure), and hopefully your heating will be up and running once more.

DONT bleed with the pump on as more air could be sucked in, they need bleeding in a circular sequence to push all the air out. You may need to do this daily for a few days. If this doesnt work get a plumber to flush the system.

check that the bleed valve is not getting blocked, try poking a piece of fine wire into the hole with the valve removed. be ready to either turn off the rad or get the valve screwed back in pronto. if the rad has a thermostatic valve it could be sticking they are prone to this.

Sounds like your system is low on water. Check the boiler feed valve.

Firstly, make sure both taps either side of radiator are fully open, then open the bleed valve and see what happens; best to try with the water pump running (central heating). Hope you have success with this.

you need to bleed all the radiators at the same time to get rid of the air pocket. You may need to drain and refil the whole system.

when you bleed radiators you you need to do all of them,if that does not work then you might have an air blockage in the system that will need to be sorted out

Sorry cant give an opinion on this one. Get a plumber is the safest option.
