Here's another idea. Heated floor mats that are designed to go under carpeting.

So, a layer of dri-core, then carpet pad, then heated floor mat, then carpet. But, not exactly a cheap way to go. May not have to do entire floor, but enough of the floor to allow the floor to radiate heat instead of coldness.

For my room 11 x 12, 2 of the 5.5 x 8 floor mats would pretty much cover it. Just leave a few feet unheated near the screen end. Cost $600.
