On overcast days, it was about 10 degrees warmer inside from the sun, and out of the wind, it felt like the tropics. I was very comfortable stripping and sanding. The temps went down at night though, so Titebond turned white and came undone. I understand some glues don't have this problem. I had an old-fashioned propane radiator that I used on days I needed to fiberglass. Ultimately, this was only marginally successful. When it was 20 outside, I got it up to 45-50. I didn't mind that the Raka took 5 days to harden. I did a less than perfect job glassing the interior because it didn't flow very well. If I had waited for balmy days, even that would have been more successful.
Condensation was a minor problem. Especially with snow on the plastic (I routinely shook it off the top, but it was 6' up the sides this year), it was like a tent when you wake up in the winter. It would snow or rain inside when you shook it first thing in the am. Tools get a light rust after a few months if not kept up.
I think those tank-shaped contractors propane heaters would have the place toasty quickly. With my leaky doors at each end (necessary for hot days), there was plenty of ventilation to make a kerosene heater feasible too. I tried a small electric space heater, and an quartz heater. They blew my circuits so I couldn't tell how they would work.
If you want it warm enough to work comfortably, this will do. If you want an inside climate, you need to keep looking.

Is there any viable way to heat this kind of shed? I am interested in
