is it a closed or vented system? that is to say - combi boiler or tank in the loft and a hot water cylinder somewhere.

vented can be poured into the loft tank as it is refilled, but as you mention pressure, it's probably combi so it goes in through an upstairs rad (towel rails are good as the plugs are often on top) carefully funneled into the end plug on a normal rad (if there is one) or pumped into the filling loop with a kit like a rapid dose. pressure is restored by opening the filling loop till the pressure is up at say 2 bar, then bleeding all the rads and topping the pressure to the region of 1 to 1.5 bar

See FAQ's for advice on filling a system with a filling loop or a WB internal charge key. Better still your MI's.
