But the insulation must make a difference - I figured that heat rises,
and can't rise as efficiently if the ceiling is insulated. Just
wondered if anybody had experienced this, or if there was a heating
contractor who'd encountered this problem.

It is not "free" heat because without the insulation some of the heat (a
small amount) will move upstairs and then the basement will get cooler
calling for more heat. I suggest that unless you need the heat down there,
turn it down as far as it can go or turn it off.
