Also, do you use only one UTH or do you have one on each side? I find that colder areas, and homes, require the use of a UTH on each side with a thermostat for each one. More expensive in the initial output, but a lot better for stable temps in the longrun.
Yep, I have only 1 UTH on the hiding place, however the room temperature is 80 degrees, but do you think that I should place another UTH at the other end, or above the other one, you know, on the side?
