Sorry for stupid question but if you don't know you don't know.

Can I turn off the 'bypass radiator" in the hall (has no TRV) as long as I keep another radiator, (any other, somewhere) open?

Or is this bypass radiator somehow plumbed differently and must never be closed?
 
Yes that’s fine if it’s one with a trv best to remove the head then you can shut it
 
Thanks, basically I moved the thermostat from the hall to the living room. The hall radiator is the only one without a TRV so was worried about closing it (don't want this rad on anymore, cost of living you know!) But two big rads in the living room will remain open at all times. Just don't want to break the pump or blow up the boiler! I guess the purpose of the "bypass rad" is just to ensure there is some sort of heat sink?
 
Exactly and for somewhere for the pump to pump when the trvs shut etc hence removing a trv head
 
On one rad yes think some models still have a max temp then they shut off so best to remove

Hmm, wouldn't know how to go about doing that, I assume the whole system would need depressurised? Fairly sure on the max setting it should be "always open". (this is the type I have)

But I don't know for sure about these things
 
Do you see below the openings there is a line bottom side turns eg undo it til it stops then hold the valve and lift / pull the top off might be tight so might need a wiggle

The valve is a danfoss ras c2
 
Ah I see, so if I take the plastic top off that will stop it closing ever? I just assumed the actual valve control was inside the brass gubbins. Didn't realise the "top bit" did the thermo stuff. So this is it fully and forever open now?
