This may or may not be true. And if true, may or may not be a issue. I know that in my truck, my camper, or house, it has never been a issue for me. AFAIK, the real difference is you use one over, the other under you. Somebody told me heat goes up.
Hot/heated air does indeed go up.
Radiant heat radiates up, down, sideways ... wherever the surface(s) of the source(s) are pointing.
The hot wires in either a mattress pad or an electric blanket shoot out their radiant heat all around the wires up, down, sideways, etc.. I know ... as I've used electric blankets on top of me for decades, and they in fact do warm me just fine when lying under the bottom side of the blanket. ;)
P.S. Now - for the real challenge - how many of us RV'ers use electric mattress pads or blankets when camping without hookups?
