Ferolli expansion vessel

[NEILC25]

I need a new expansion vessel, problem is I've got a optima 901 and the flue goes up about a foot and then into the back wall and the vessel is at the back, it's one of the round ones, I've got to get a engineer into do it, I'm assuming that they take the flue out and lift it from the back, or do they take it out from the side?

Or can you install an external one ?

As above fit an external. Cheaper and will prevent boiler dismantle again in the future.
