Replacement for Baxi 100 HE

[Stuart R]

I have a Baxi 100 HE boiler and it's been good over the 20+ year lifetime.
I'd like to replace it with something similar. I'm thinking that a boiler form the same manufacture might have connections in the same place (easier for the engineer to fit a replacement).
Question: Are some ranges of boiler made with connections in the same place? If so, can anyone suggest which boiler might be the same connections as the Baxi 100 HE.
Thanks.

i think a (baxi) main sits on the same jig.
