seen all of them but being from manchester and starting apprenticeship in the early 70's lots of high rise flats so se and u ducts, first time i saw a vertex i thought what the F*^!Never seen one, or a SE duct etc etc etc or a half the things you have to learn on your ACS .
It was a Worcester 240
I can’t really see the reason for having it over a standard flue
vertex flues the ones i cam across is an estate in lymm where they all have istors on 1st or 2nd floor flued through roof and air taken from loft spaceMy take on it: (FWIW, I have never fitted one, but came across a few).
Remember the VF is not balanced, sealed or (although I may be wrong here), fanned.
I think the VF raison d'être is ventilation. It was perfect of you had an internal room, or, say, a completely glazed exterior wall.
I cannot remember, but maybe there were no vertical PF's when the VF was introduced.

yes with soffitt ventsThat is pretty much the definition of a vertex installation!.
In your scenario, was the loft properly vented?
Also, I implied that that the vertex would be used in a room where normal ventilation would be awkward. Obviously, the other benefit is that there is no draughty vent in the room in which the boiler is fitted.
As long as they are big enough to support the boiler requirementsyes with soffitt vents
