Maybe if the flow from the boiler is connected to the top of the
radiator and the return to the boiler is connected to the bottom of
the radiator you might get some natural (gravity) circulation. The
tappings for the radiator would need to be as close to the boiler as
possible. (i.e. like a gravity H/W tank)

Not with microbore pipe!

It's no use frigging about - but far better to move the pump nearer to the
boiler. The rad tapping can then be *after* the pump - and it will work
fine.
