Heating Vaillant boiler?

How easy is it to change a expansion vessel on a vaillant VCW-BG242 Eh Boiler and how do you go about it

The boiler would need to be removed from the wall to carry out expansion vessel replacement. The vessel is on the back of the boiler, once off the wall the process of replacement will become evident and straightforward.

An easier solution may be to fit an external expansion vessel if the room for it is available.
