Heating a cold-climate off-grid superinsulated house
The house will be in New England, northern zone 5, high elevation, open to north winds. Good southern exposure but lots of windows for north view. Cathedral ceilings up to 18-20. Proposed insulation R40 walls, R65 roof, triple glazed European windows; very tight. (<1.0ACH50) There will be a PV system with battery back up and possibly solar thermal. Do minisplits work for off grid situations? Solar thermal with radiant wall heaters? Anyone have experience with superinsulated off grid homes in this climate?
