Confused — We are in the process of remodeling a home in upper N.H.
We have used Zip R on the exterior sheeting, Zip board on the roof sheeting and foamed the interior to R-27 wall and R-38 roof. We were ready to install radiant floor heat using warm board.
I am thinking mini split for the 2nd floor bedroom and return hot water for the main floor and basement.

I think you forgot to ask a question.
Like Martin , I think something is missing . if your structure is already standing and you are going to do radiant floor I suggest WarmBoard R . I also suggest having a detailed room by room neat loss done by someone qualified , someone not restrained by what the program he is using tells him . A proper design will be key to you not receiving a terrib;le job by someone stating they are an expert .
Perhaps the clue to your unasked question can be found in your first word: "confused." Perhaps you are asking, "How should we heat this home?"
