Why? *Surely if your boiler is powerful enough you don't need to mess around like this. *If your boiler can't heat all the radiators at once, your boiler is too small for the system. *Even with all my radiators on full blast, the boiler doesn't run continuously.

I suspect then you have a microbore (8mm, 10mm) sealed system radially
distributed by a central manifold. Must not be operated without
corrosion inhibitor else you will possibly not be able to flush the
crap out the radiators while in situ. No leaks are tolerable, and
less likely.
