Hi guys, I am pricing for a large heating job and looking for some advice to aid my confusion!!. The new extension is considerably larger than the existing cottage, and materially very different, I intend to use the whole house calculation to size the boiler my head is swimming because the new and the old will require very different heat requirements, would it be better to separate the two buildings, I am commited to getting the right system for this job, I am sure I will raise many more questions so apologies in advance, thanks guys!:willy_nilly:
