I'm insulating, sheetrocking, plumbing, and rewiring my garage to make
it a more comfortable place for year-round woodworking. (yes, this
is California, but it gets down to below freezing in the winter and
into the 100's during the summer up here in the northern end of the
state). I'd like to heat the shop in winter and felt natural gas
is the best choice from a cost and convenience point of view (there
is gas already present for the water heater). My question is:
What type of furnace would be best for this situation?
I recall a similar topic came up several months ago, so perhaps
someone can help out here. I'm concerned with a large flame in a
room full of sawdust, but a friend with a larger commercial shop
has that exact situation. In fact, I was just in a huge high school
shop last week and they too had two gas furnaces hanging from the
ceiling. The two types of gas furnaces I'm aware of are the wall
type and unit heaters. Unit heaters are the large beasts that hang from
the ceiling in commercial buildings (they come in smaller sizes also).
Cost for either type is roughly $250-300 range (furnace only).
