I use this dimmer and I'm pretty happy with it. I still keep a constant watch on temps because the temps vary in our house throughout the day.

If the UTH is suppose to cover 35% of the floor, then I'd say mine is too small even though I went by what it stated on the package. Is 35% what is recommended?
