Removing Radiator with Danfoss Thermostat

[JimOram]

Usual story, I want to remove a radiator to decorate but I'm not confident I've found the LOCKSHIELD VALVE. The radiator has a Danfoss Thermostat. When I remove the thermos cover, I can see a pin (that's pushed in and out controlling the temperature) protruding from the center of a nut. Will turning this nut isolate the radiator so that it can be removed? I don't want to unscrew this if it just removes the "pin parts". There's nothing else that could be used to isolate the radiator so I'm guessing this nut is what I'm looking for.

No,put it back altogether again see this picture assuming it similar TVR and on the right you will see the thread which is already in your radiator and the nut nearest to it is the one you undo

If you're not confident,you can loosen both nut on each side and lower the radiator onto the floor supported with timber packing of the floor height then tighten up nuts again.Personally I would do it this way as it has been known the TVR open up and let out water if you removed the radiator.

Thanks for responding so fast.

So, to make sure I've understood...

I can, if confident enough, just turn the valve to off (the cold symbol) as well as the one on the other side of the radiator, and remove and drain the radiator. The trouble with this is that water can still come out of the valve.

Alternatively, I can roll down the radiator, a process I'm familiar with.

Assuming I've got that straight, I have a couple of questions...

How much water are we talking about? Are we talking about a situation where it floods my house while I'm out or is it managable with towels, etc.

Can I cap it if I decide to remove? Someone mentioned this to me but I've not seen any ca[s in the stores. I could go to a specialist plumbing merchant if such parts exist. Any ideas?

Just to clarify the situation. The Lockshield valve is on the opposite side of the radiator with a small plastic cover which needs to be removed so you can turn the valve off before slackening the coupling nuts between valves and radiator.
I follow what masonsa is saying, providing you can unhook the radiator from the wall brackets, you can leave the radiator laying horizontal as against vertical while you decorate behind it.

i can answer that one.

the water you will have will fill a bowl (or two) it is what you have inside the radiator now.

yes you can turn both off and remove radiator, but as it is a TRV you MUST cap it otherwise if the trv "senses" the room is too cold it will open up and allow as much water as your sytem has onto the floor

Depending what TVR model you've got,I've heard they can open up if the room temperature is cold,but I would still cap it anyway.Pop down to the plumbing merchant to get something made up to cap the TVR or as you said "Alternatively, I can roll down the radiator, a process I'm familiar with".As usual put down old rag/towel round pipe area.

Yes you can obtain 'capping plugs'. The type you are looking for is similar to the coupling nut but without any hole through and inside it is fitted with a rubber disc, obtained one a month ago from B & Q warehouse.
There are other types of capping plugs available

Sorry, forgot to mention if you want to lower your radiator,you might not be able to unhook the radiator off the brackets if the bottom pipe is in floor screed as there'll be no movement to allow you to do it.
