Speaking of which, I want to get Thermostatic Valves for the upstairs
bedrooms, as they get hot a lot quicker than the ambient temperature
downstairs where the main thermostat is. Any recommendations on good,
reliable makes? I've heard a few stories about some of them getting stuck
on/off and doing buggar all after a while ...

I've heard they last 10 years or so. I replaced the old ones here with
this tpe:

they work, and no noise like with some.

Of course it means a drain down and you may have to replace the old
olive. I think very old valves have an imperial thread even. While
your doing this you could re-plumb the new rad so you dont need
extenders.
