Confused As Hell - Boilers

[snb1]

remember diversity (BS6400-1 only applies if more than 2 appliances fitted )for combi boilers is 0.8 , cookers is 0..4
30*08
11*0.4
24*.8
that only equates to 47.6kw so well within spec

Would you apply it to 2 combis?

Do the 2 rooms in the outbuilding require HW from the new boiler?

Until the op tells us what the 2 rooms usage is all discussion is pointless. I suspect the brief was vague and it generated so many options..
