The 2 corners where I think would be viable installation locations open out to either the front of our house, or a) too near electrical service or b) Inside of a screened porch. I can't find pictures of what the exhaust looks like on the outside but from what I've found in installation manuals, it requires a 10" square that is going to overlap multiple pieces of siding. Sounds ugly for the front of the house. I am confused as to why these stoves are so inefficient and therefore have large exhausts. We just want to warm up our living room so it is nice and comfortable and toasty. Our forced hot air setup leaves us dried out, drafty and is not inviting at all. If I exhaust UP instead of OUT, with a gas stove, do I still need to use the $$$ triple wall DuraVent type chimney, or can I use cheap pipe like my "Power vented" Furnace uses?? Is there any other product I'm missing out on??
