Anybody use a hobby evaporator (Halfpint, Mason, Starcat, etc.) as a wood stove when not making syrup?

I have a stainless cover for my Halfpint (14 or 16 gauge custom) and I'm considering using it (with a gasket and blocks on the corners to hold it down) to heat the shed while working out there until the sap starts running. Wonder if anyone's done something similar?
