Radiator only hot when turned right up

Hi. One radiator is my house is only warming up when it is turned to just above 3 on the dial ( I don't know the technical term). I'd like to keep it on 1-2 during the night but it stays stone cold. My FIL bled all the radiators a month ago, does this mean it needs doing again? Any advice would be gratefully received! Thanks

Hi, it sounds like a possible faulty thermostatic valve to me, also make sure the thermostatic head is screwed on correctly.
