As high as you can get it - the higher, the easier to bleed. If you can
manage a couple of foot (60cm), that works very well.

Any chance you could convert to a sealed system? Saves loads of hassle
in this circumstance.

what boiler and system have you as you could convert to a sealed
system, These work better and you dont need a feed and expansion tank
just a small expansion vessel.

Provided your boiler is suitable, why not take the opportunity to convert to
a sealed (non-vented) system? Then you won't need an expansion tank at all.

The expansion tank should (boiler permitting) be dispensed with altogether.
