What type of heating do you use? Any recommendations to heat
my shop: it's about 20x20 with a 12 foot ceiling.

Solar (unshielded remote fusion reactor). I have a 50x50x14 shop
and plan to heat it with three 6x12 panels this winter. Last
winter I used a single 6x12 panel to keep shop temperature above
freezing; and estimate that three will provide a comfortable
daytime working environment (most days).

I don't know about your locale; but a shop the size of yours here
could probably be kept decently warm with a pair of south-facing
6x8 solar panels. The advantage, of course, is that there isn't
any fuel requirement.
