Hi Tony,
Solar would be nice but would definitely be more work than most other
choices!
Our shop has about 200 square foot more than yours and the winter
temps are definitely colder here than in North Texas where you're
located.
I'll talk to Susan about your arrangement since she has been in your
shop and can relate to it in size and comfort level.
Thanks!
Brad
