Lol just bleed the damn thing. 1.5 bar of pressure behind the air bubble, its coming out if the waters hot or cold
Central heating should be very scientific and predictable. But it isn't

Have you got a drain on that rad ? if so connect up a hose and open it up about half way and turn the fill valve on, or use one of the kids/wife for this, let it run for a few minutes, then shut off at rad and fill valve, check pressure and listen for noise ! I assume you have checked the ABV on the boiler is ok ?

will have to cheak this but as the thermostatic valve and shut off valve would save to be swaped for feed and return can this make a differance ?
i can only explain it as bubbling for about the first 10 or 20mins

specialy if they are not fitted on the flow. the older ones aren't suitable to be fitted on the return and the valve chatters .newer ones can be fitted on flow or return

ok up date it took a while and been hetic for the last few weeks
any how i had one of my i cant sleep nights so i was up before the heating come on this morning
checked and found the trv on the rad in the front room and the one in the hallway ar the wrong way round the hot is on the shut off valve and the trv is on the cold side when heat comes through
as bright spark said these are not old 4 years ago but on the chance of there causing the problem whats the easy way to swap them over
its a combi boiler so reducing the presure in the boiler will allow me to remove only one side at a time but if i have to remove the piece that is in the rad as well im thinking drain the system is going to be easyer ? just means a good chunk on addatives again as well
other way reduce the boiler pressuse change one side on the pipe shut off the new valve do the other side chane that valve on the pipe and then remove the rad and change the fittings in the rad and hope it all lines up
