Hello to all. My name is Mike and I am more or less a lazy prepper. I am planning on moving this fall to an area near Pittsburgh and hopefully buy a small hunting camp or some such setup with my brother and his wife.

Please try to excuse my digression as my mind not only wanders, it sometimes leaves me altogether . . . . .

Hypothetically let's say we use a 55 gallon drum for our furnace. We all know the basic setup, but to improve heat transfer/dissipation could we weld fins on the sides of the drum. They would run at an angle going upward to the front. This would add additional surface area for heat transfer. It would also give a subtle 'push' to the heat released so that it would go forward into the room, to a degree, instead of straight up.

OR

3" or 4" 'duct pipe' could be welded to the sides of the drum. Each end (both top and bottom) would be facing forward into the room. This would cause a draw at the bottom to pull in cool air from the floor and again force warm air out into the living area instead of straight up. Once started, this would create additional circulation in the room.

I feel that the 'duct pipe' scenario would work best to increase surface area AND force more warm air into the living area.

Now then, would this adversely affect the combustion in the top of the barrel? By increasing surface area one might think that the internal temperature could possibly be lowered. I realize that this could affect the efficiency and possibly the natural operation of the furnace. Obviously this would need to be put to the test. I myself will not be able to try this until I move, but it seems like it might make the heating more efficient and comfortable. Just a thought.

So, what do you think?
