BS!
You forget about or don't know how bulk insulation works. It's sole purpose is to prevent air movement in the insulated space thus eliminating convection heat loss. All bulk insulation...

"bubble crap"
I agree!
Look at the emissivity of the low temp 80 deg. subfloor radiating downward to its receptors, looking at either a properly placed and transparent bubble and aluminized reflective film or,...

Ah, come on, AC!
The atoms may be moving within the air molecules but the air substance may be stationary, at zero velocity, for heat transfer purposes.
Natural convection is a gravitionual...

Jeff, You have a point, being that inasmuch as that the upward facing 'visable surface' of the bat will absorb downward radiant energy from the subfloor and, because of its low mass, will quickly...

Do we agree that there is no gravitational forcing function to cause convection heat transfer in the downward direction beneath a heated floor? By conduction transfer, the warmest, lowest density...

Adding clarity to coluqualisms
'Heat' does not "rise" in any sense of the word. Heat energy flows from a hotter body to a colder body by any or all of the stated means.
In Convection heat transfer, a hot (lighter) fluid may rise...

The black wires in and out are thru a current sensing resistor. The red wires are just a pass thru so only one needed to power the meter and could be tied to the other side of 220AC or to neutral.
