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.
I have a question, how do you insulate a screen top? And how the ball is going to get fresh air? Excuse my ignorance, please!
