Well?
No idea because I moved out in 2010. But I did have a similar problem with one of the radiators in this house and it turned out the valve was stuck - I watched a video on YouTube of how to fix it.
In case that’s why you were asking
ETA which is what I was supposed to do in the old place but clearly didn’t bother despite the advice

@tis the time of year !
I've just re-read this, and had a thought.
Unlikely. but some rad designs are meant to have a low surface temperature - for safety reasons.
I know someone [not me] who bought a house locally, one of the previous occupants had been a bit of a DIYer and they had installed a mixture of rads (and a towel rail type, but not in the bathroom !). the rads also included two different low surface temperature designs and three different manufacturers of the 'normal' ones ... The whole system took a bit of playing with to get it balanced, but that was achieved. Only had to change one rad and that was because it leaked.

How does that even work? Radiators are supposed to radiate heat - if the heat isn't present at the surface of the rad, how does it get transmitted to the air further away?

The rad is covered / cased to prevent it being touched directly, this doesn't prevent heating by convection ie warmed air ...

I'm not laughing at you - it's a really good question. and I've always thought that about those decorative radiator covers - some heat must get trapped inside surely?How does that even work?

Yeah, some heat does get trapped - the case itself gets warm and then re-radiates some of that heat. It's not really significant in a properly designed system.
When calculating rad sizes etc, there is an estimated loss to allow for when using covers - I can't remember the exact amount, if using trvs you'll end up varying the setting anyway, to achieve the relative warmth ...
Don't know why they ended up being called radiators as most of the heat is transferred by convection.How does that even work? Radiators are supposed to radiate heat - if the heat isn't present at the surface of the rad, how does it get transmitted to the air further away?
