How do I remove a c/h radiator and fit stop ends?

[verdigris]

I need to remove a radiator but leave pipework (10mm copper) sealed off under the floorboards. What is the best way to do this? I have ordered two brass 10mm compresssion cap ends.

Turn off mains cold water.
Drain central heating system from lowest point.
Cut pipes.
Cap off pipes.
Turn water back on.
Bleed all radiators.
Turn on heating / Test.

Thanks for that. That does seem to be the sensible way to do it.
I am on a Combi boiler and a 10 mm system. I was hoping not to have to drain the system. If I shut down all radiators at both ends, so no pressure from them. Would it be possible to cut the pipe and quickly put the stop end on with only slight leakage?

I think you would be wise to call in expert help. The task is very simple but can end up causing damage. You are asking for guidance up front, which is comendable, but if things start to go belly up, you will be in deep water (no pun intended). Good luck

Thanks for that. Perhaps I can get BGas to renew the water in the system and do the capping then. The Fernox or whatever they use has been in the system about six years. How often should it be renewed? I mentioned it at the last service and got a 'not necessary' answer.
