I have a shop in the garage and I am currently heating it with K1 and a small radiant heater. I live in Northern Ohio, so the winters can get a bit chilly. I do not keep heat on all the time, only when I want to work of projects, generally weekends and some of the warmer nights. I do get a bit concerned with wood dust, but fortunately I have not had any problems as of yet.
What would any of you suggest as a good heating system? I do have Natural Gas.
