How do you heat your workshop? Ours is currently not heated. It has no insulation but it is well ventilated. We just got it set up in October and it is far too cold to work out there in our winters. It has a limited amount of electricity as it is not on it's own circuit, what is the best way, in your opinion, to heat it? We are considering a propane heater that goes on top of a propane tank (like for a BBQ)
