Do we need a warm garage....

The through the wall vs through the roof argument will go on forever. It worried me to cut a hole in an almost new roof but the advantages of not needing double insulated elbows and not needing any pipe supports tilted it to the roof. A properly installed roof flashing will last a long time.

Yeah, no argument from me. Use what works for you. I don't have any double elbows or pipe supports. Very easy to disassemble and clean if needed. Minimal heat loss. Works for me.

My concern is snow accumulation taking out the chimney on the roof. My neighbor down the road had his taken off by snow last winter. He just installed a propane furnace and took the exhaust through the wall. Said he would never go through the roof again. He gave me his wood stove for my new pole barn so now I'm worried about a through the roof chimney. We do get an average of 3-4 foot of snow. Is this a valid concern?

Hopefully those with roof chimneys can chime in with suggestions. That would suck and could be catastrophic.

I don't know how you guys that get that much snow live like that!!!!

My wood burner stack is through the roof been there since 1978. We average over 60" of snow and in early 2000s had over 100" of snow.Most 90+ furnaces will go through the wall cause the cooler warm air does not have the rise. They do have a special stack that can through the roof.

Yeah my 90+ propane furnace in the shop is vented thru the wall with plastic pipe.

When we get temps below 20F and dry air I can shut my wood stove damper all the way and my stove will still draft. So I know my setup works well in that regard. If I was struggling with it I would move to roof exit if I thought it needed it. Otherwise, for me, I just prefer going thru the wall.

We are cold enough it'll all be snow. Been spitting off and on for a couple hours. Coming from the South. I just got back from the farm which is 6 miles South of here. Ground is mostly white there. Just dusting laying around here. 21 degrees SE wind 5 mph.

I'm scratching my head on this. We get an average snowfall of 6 to 7 feet per year and usually build up a maximum of about 3 feet on the ground. The pole barn roof gets less buildup because of more heating from the sun and it will slide off. My chimney sticks up about 5 feet above the roof surface. I never notice any snow piling up abnormally around it and I've never heard of a chimney affected by snow.
