If the expansion vessel and centred flue were that of the Rapid then it would be perfect!
Ah, gotcha!
I'm inclined to agree about the centralised flue, and I understand that the next generation of all models will have that.
Not so sure about the expansion though. I'm quite a fan of separate expansion, both in terms of access, and to keep the boiler casing small. And, (although I appreciate you GSR types might not see it the same way) it can be maintained by a non-GSR engineer.
