Temporarily removing a Victorian-style radiator

[Rouleur]

We could do with moving two of the below rads out of the way to allow the room to be carpeted. This may be a silly question but would closing the valves on either side allow me to unbolt them from the pipes without having to drain the system? In my head doing so would isolate the rads.

Or is it not a major problem for a carpet fitter to work around them?

Thanks very much for the advice.

One further question - will the heating system still work with the rads disconnected?
