Sealed system Rad - need to take out for 4 days
Discussion
I'm having my place painted and need to take out a rad out of a sealed system (It's too close to the wall to get behind and paint in any way shape or form.
Does it matter that it's on a sealed system?
I have thermostatic rad valves on the radiator, so can I just close them off and take off the radiator (Obviously catching all the water from the radiator?
Assuming this is all ok, when I put it back, do I need to do anything clever to re-fit the radiator and topping up the system?
Hope this makes sense?

just thought, do I need to drain the whole system?

Just to say Thanks for the advice, taken me a while to come back as in Barcelona right now.
- I definatly cannot get a roller behind the radiator, it's far too tight
- I like the idea of putting the rad at 90 degrees, but not sure I dare do this
- I think capping it off by closing the TRV, using the allen key and then putting a cap on.
My wife went to get the end caps and has come back with some washers which don't really seem to fit too well. If I use them, I reckon I'll ruin them in the process.

Should be able to get some brass caps with a fibre washer in them to go over where the rad comes off.
Locking off the valves should in theory be okay. But if you have a TRV, this'll open if the temperatures drop too low to prevent freezing. When these were installed you should have been given a cap that screws down onto the TRV instead of the actuator head.
Yes, it just seems that the washers are a little too big. I'll be using the allen key to close the valve, and will check through my spares to see what other washers I haveLocking off the valves should in theory be okay.

Just thought I would update this as I did this last night with a firend and the radiator is now off and despite a little water leakage... our own fault for not properly turning off the TRV and the pressurised water coming out a little, all went well.
Some learnings for the amateurs amongst us.
- Think about the wieght of the radiator with water in (Mine was very large) as it's heavier than you think.
- Make sure your friend is at the TRV end as any pressurised water will splash him (Ha Ha)
- First time round took an hour (I know it seems like ages, but we were very cautious), next time will be about 20 mins per rad
- It was a good tip to put your finger in the holes to stop water coming out... make sure you have plenty of buckets/towel just in case
Thanks to all who contributed... just need to re-hang in a couple of days
