Jim,
Interesting comparison.
2" underfloor insulation seems a bit too thin, i use 4", which in metric units is R2.5 and this is in mild temperate Melbourne, Australia with annual average temperature of 15C.
What temperatures did you enter forSite:GroundTemperature:BuildingSurface? i would check the heat losses through the floor for the radiant case.
Cannot remember how to access the attached idf. How to access attachments?
regards ooi
