Another radiator problem

    OK so I have a sealed heating system with one radiator that's cold at the top / middle hot at the bottom, I know the the obvious answer is bleed it which I am doing constantly, air comes out and you can hear a gurgling sound from the in pipe like more air coming in.
    Do I have a leak?
    Or not enough water in my system?
    any ideas?
    Thanks

    What is the pressure showing on the pressure gauge?

    I meant the pressure on the pressure gauge beside your filling valve or on the boiler. Pressure of the expansion vessel cannot be checked unless water was drained away from the vessel.

    You need to turn on the filling valve and bring the pressure back to just over 1 bar. Then re-bleed all the radiators and then again bring the pressure back to just over 1 bar.
    Check pressure relief valve discharge pipe for leakage and all automatic air vents in the whole system for leaks.
    If nothing found keep an eye on the pressure over the next few days.
