Hello I hope someone can help!!!
I have 2 rads in an fairly new extension (2006). I noticed they were cold and so have bled them but there is no air in there as water comes straight out. I did find a radyesterday which needed bledding in the bathroom so did this with the system off and then represurised the combi system after to 1. The rads came on and worked fine yesterday however today I woke and switched on the system to find the same 2 rads arnt working again-however no rad needs bleding and the pressure seems fine.
Does anyone have a clue what I can do please as it is Arctic
Thanks

Its clear that the water is taking the easy route back to the boiler.
Therefore, its a question of balance.
Has someone altered the lock shield valves?
Turn down each of the working radiators down to re-distribute the water.
