[b]Hi, I have just changed the radiator after decorating our bedroom. But seem unable to get the air out of the system. I have bleed all radiators a number of times and there is a quite regular gush of air/bubbles running to the radiators, any thoughts please?[/b]
another thought is bleed your radiators one at a time from the ground floor and lock each one off by the valves on both sides ( make sure boiler is off)then open both sides of the radiator that is cold and turn your boiler on. Keep bleeding until all air has been pumped out.
