Thank you all for your help. Tried all suggestions without any luck so called in local heating engineer who spent an hour trying all those suggestions too. Conclusion is blocked pipes so having some pipe work replaced. Half a day’s work, apparently. Oh well, at least I learnt a few things that...

Opposite valves are open. Screwed all the way upwards. ?

Cheers. It’s a Valliant Ecotec pro 28. 10 years old. Should the pin push in all the way? It does in the bedroom but only moves slightly in the hall. Different make valves though.

Checked pin on bedroom thermo and it appears to be fine. That rad is lukewarm at the top now. Cold at bottom. Heating been on a couple of hours. Other rads very hot. Except the original problem one, of course. Might be time to call a plumber!

Okay, done that but, unfortunately, hasn’t worked. Water in rad seemed okay. Bits of black stuff (magnetite?) but was free-flowing. Water n and out pretty much the same. New evidence though: Discovered rad in bedroom (nearest to combi boiler) is also cold. The pipe with the thermo valve on is...
