How to heat

Hey guys,

I recently had my shop built and among the things on my to do list is figure out how to heat it. I’d like an electric heater but don’t want it to run up my power bill. I’d also like to maximize my floor space as my shop is only 720 square feet. I was also thinking about a wood stove (I’ve never owned a wood stove).

What do you guys think?

Thanks.
