Changing the always on radiator?

sevenhills

The boiler is less than 2 years old, I am not sure where the thermostat is. The photo is the rad at the bottom of the stairs, all the other rads have a on/off valve.
The control is a 'Danfoss' in the kitchen, also less than 2 years old, but very low tech.
The boiler is a Worcester, cannot see any model numbers, I will have another look and get back.

The thermostat will be fairly obvious.. It will probably look something like this -

Should be pretty easy to spot and should be in the hallway.

I guess I meant the thermometer which gives the temperature reading and then switches the rads off.

this is what switches the rads off

That is a valve not a TRV but a lockshield and there will be one at the other end. If you unscrew the screw the plastic cap will come off and the valve turned clockwise will shut off the flow, do this at both ends. Then open the ones on the radiator in the lounge, does it have similar valves or TRVs, like a big knob with numbers on it.
If it has a TRV then you can unscrew the valve head and this will leave it fully open.

Count the number of turns (and make a note of it) so that you can reset the valve to its original setting later on. No need to mess with the lockshield at the other end as water won't flow through the radiator.

Note - Messing with the lockshields could upset the balance of the system and result in one or more radiators running hotter than others.

Think you wrong you will need to turn off at both ends

So please. Explain how a TRV will stop the flow of water through a radiator when only one is fitted and there is a lockshield on the other side.

Nah freebear is right, but you might get a small amount of flow/convection through the open valve
