New radiator goes cold after an hour

[Andrew Morris]

Hi again guys funny thing is it cloudve been the trv or balancing. I've done some adjustment to both and the radiator is staying on all the time now and every radiator is running red hot. When looking at the balancing around the house every lockshield was fully open so I'm guessing these rads had no chance really. I really do appreciate the time and effort you his took in trying to help me out I really appreciate it
