It's hard for me to say for several reasons:
- We have a machine shop in the garage. The lathe and mill draw 220 3-phase; running them is like running three dryers simultaneously.
- I have a dedicated small chest freezer for snake food. It's in the herp room so the exhaust from it helps heat the room. As a result the room doesn't need supplemental heat in the winter, but in the summer it can actually get too hot in there if I'm not careful.
