Use heat duct as fireplace pipe

[Waterdownredneck]

Hi all, my chimney pipe fell apart and I need to get a new one. I use an old fireplace with the top sides cut off and hotel pans, been going great for years. Rather than expensive fireplace stove pipe do you think 8” heat ducting would work for the rest of this year? Thanks for your thoughts.

Yes it will work for this year

Heat duct (28 or 30 ga) won't hold up with the extreme heat, but you can use 24ga stove pipe, it will give you a few years.

I used heat duct on my first homemade evaporator. I didn't have a blower and i don't think i was getting as hot as most evaporators, though i did get a pretty decent boil. Anyway the heat duct lasted a couple years. Lasted longer than the body of the (not insulated) evaporator, which warped terribly and was unusable after three years.

By the way, your setup sounds very similar to my first evaporator i made! http://mapletrader.com/community/showthread.php?29303-Evaporator-from-small-wood-burning-stove-cheap!
