My garage is 3 car (864 sq. ft.) I would like a top load wood stove something like Harmans TL300 but I think that would be overkill, I have insulated doors (1) 16x8 and (1) 9x8, 10' ceilings 2x4 walls with rolled insulation and blown in attic; the garage is pretty tight and easy to heat. I will eventually leave the entry door to the house open, except screen. Is there any smaller stoves anyone can recommend with a lot of these same features? Or will the TL300 tame down this low? I like the idea of the handle also moving the damper for the top load. I also would like a non cat. stove. Thank you
