Default Noisy TRV.

Now the radiator (or just the valve?) makes a loud noise when the
system is running - not quite a hissing noise - more like a "rushing

Is the TRV bi-directional? If it is, you may well have installed it set
for the 'wrong' direction. If it's like ours, you simply remove the
sensor head, rotate a collar and then reinstall the head. No need to get
wet!
