    heat loss is heat loss whether its for radiant or warm air....i think the loopcad helps you determine whether the radiant will satisfy the heat load or add supplemental heat. i have used the loopcad for multiple radiant and snowmelt jobs great results ....i have also done these jobs without it

    Correct, only MJ8 does cooling loads. You can switch between MJ8 and ASHRAE on the heating side. There are some differences in the calculations, but from a designer standpoint the real difference is different climate databases and differing abilities to create custom roof/ceiling assemblies.
