I have removed and replaced a radiator on my system and now the pressure is low. Can you show me how to represurise the system. Do I need a special key for the boiler valve?

there is usually a tap - looks like a little wheel i think. It is placed somewhere under the boiler - can be hard to locate (mine is actally beneth the boiler and to the right - so its a bit awkward to access) - but its there, and you can correct the pressure quite easily.
