  • 120 to 130 for below floor (AKA: staple up) heating

Wow, that would indicate that in slab would be MUCH more efficient. Especially in a heat pump situation I'd imagine. I knew under floor had to be pretty hot, but its nice to see on top of floor in the mix too. Good info AC Hacker!

I'll hopefully contribute to this thread soon, been so stinkin busy lately.
