Radiator problem

I have a problem with the last radiator upstairs, when the heating is on, it stays cold, so i turn the heating off and bleed out all the air in the radiator, it then fills up with hot water, as soon as i turn the heating back on the radiator drops cold and fills back up with air again !!

Ive tryed numerous things but nothing seems to work
Has anyone got any ideas ??

Whats the proper procedure for balancing the radiators ?

Constantly filling with air is not a balance problem. You must find why air is getting into your system. If it's a fully pumped open vented system, then its likely to be pulling air down the vent. You need to tell us more about your system type.

Even if there is an air problem the rad should still get hot.

Have you checked for a blocked feed?

The site FAQs give info on balancing and checking feeds.

Not sure were you mean, at the TRV ?

The rad does fill with hot water when your bleeding it , once all the airs gone and you re-start the heating it slowly goes cold and fill back up with air again
