How to heat

Good looking shop, same square footage as mine, my only regret was not putting in-floor heating when I built it. As mentioned, good insulation will go a long way to keeping costs down, something I still need to do. Had my last garage well insulated, was only 440 square feet, did not have heat, but was noticeably warmer to work in winter. Wood will probably be the most economical choice, maybe a pellet stove type, and use fans to circulate the air, I am still considering adding heat at some point, when I can afford it.
