The smaller the heater, the less exhaust

... and the less exhaust, the less water vapor you'll have. I had a pretty big heater, and when used a lot, there'd be plenty of condensation on everything that was cold metal or cold glass. When I was a little kid my dad heated a 2+ car garage with a very small style of blower heater, and I don't recall condensation issues, but the place never got very warm either, maybe 40 degrees was the best it would do in cold weather. That's why I think a heater that's too small to cause issues with exhaust fumes or moisture condensation might be too small to provide a truly "warm" work environment, but I'm just "putting two and two together" on that score based on the little bit I've seen.
