Could be a motorised value that isn't working fully
I think I have that problem. In the summer when the hot water is on the radiators come on too. TRVs help but I really need to get the valve checked/replaced.
Yeah thats probs it, sometimes you can change the motor or the head or sometimes you need to change the full unit if you cant change them.
