I have used this in the past when moving radiators round but never on a

On a pressurised system Id just drop the pressure to zero and cut the
pipes. You shouldnt lose too much water whilst cutting and fitting the
valves. (Interestingly enough, I also fitted full bore taps to my kickspace
heater as the small ones were too restrictive. I also got rid of the
flexible connecting pipes by using large €œU€� shaped loops of plastic 15mm
pipe thats much less restrictive and still allows the heater to be pulled
out.)
