I also put some thought to this and I think you COULD heat it with
gas. If it were me, on the back or side of the garage (least visable
side) on the outside, I would build an enclosure in which to house
the gas furnace. I would line it with sheet concrete (can be purchased
to be used behind ceramic tile in bathroom showers) to fire proof it.
The unit would have to have an outside air inlet through a water proof
grill of some sort, to provide oxy for the furnace flame, and the flue
would exit it to the outside.
Air ducts from within the garage could be run in and out of the chamber,
for the air flow. The fire box portion of the furnace is isolated from
the air flow portion (it better be if you do not want to get overcome
with fumes) so there would be no danger of an explosion. The duct work
could have seals around it to the actual wall that it passes through,
so that dust would not enter the furnace chamber.
The chamber would have a door on the outdoor side, for service to the
unit. The chamber could be from ground level up, or, higher up on
the outside wall, depending on the type of furnace selected. It would
have to have a forced air blower and should contain a furnace air
filter in the system to keep the dust from the shop out of it. Keep
plenty of filters on hand, you would probably have to change them
often. How does this sound?
