Yes a lot of heat goes up the pipe. The problem is, most of the new high performance stoves, like my Jotul, need a vertical pipe or they wont draw well. You put 2 90 degree bends in my pipe and the stove will smoke all the time, be very hard to light.

probably not a good idea to have a case of dynamite next to a wood stove-----just my opinion.

If I'm not burning locust only I have to pull it once a month +/- and clean.

I would be more scared of 12 quarts of liquid fuel sitting on top of the stove, than I would a case which used to contain dynamite.

Easy to light and draws like hell. ![[Linked Image from i.imgur.com]](https://i.imgur.com/olGX1Tj.jpg)

The OP chimney heat exchanger would be more efficient with counter flow.

Waiting for the chimney fire that takes out his barn...
That setup will fill up with creosote so fast, he will likely notice the pipe glowing red just above the stove before long.

Drawing cold air off the floor has a purpose, but doesn’t make the stove itself more efficient. Plus, it blows out the door every time it gets opened. Better to point into the room.

Fer crying out loud. Just wrap some 3” flexi pipe, in a spiral fashion, around the outside of the single wall pipe coming out of the stove.
Yeah, it’ll look silly, but no sillier than that, and it won’t make cleaning complicated, like that mess...

That setup will fill up with creosote so fast, he will likely notice the pipe glowing red just above the stove before long. Yup. All those direction changes & the low temp at the top 90. Maybe he disassembles the whole mess & cleans it monthly. Not my idea of an improvement. At the old house there was a device on the smoke pipe with a heat exchanger & a fan that came on when the coils got up to a certain temp. It worked well.

couple of small fans blowing the heat from the pipe around makes more sense than all that.

Anyone ever watch "Homestead Rescue". The head guy had pics on his home where he made a square arrangement of his flue pipes. Off the stove he teed, one went left, another tee went right, a short straight that joined both side with tees back together. All this to collect heat off the pipes.
Then an episode came along where his house burned down! Nothing ever said what caused it, but I have my idea!
A flue pipe running cold will collect creosote fast.

When ever I had to calculate the covected part of heat transfer I would write, "blah blah, reynold's number, blah blah, laminar flow, hand wave, estimate, here is my invoice for engineering"
Some smart guy now designing artificial reality at Microsoft tells me that is the best I could do because interactive air movement needs a cell size so small, no super computer could ever solve. That is why we still use wind tunnels.

Yes that would be four nineties. I am not too good with math. Thanks for the correction. I doubt my stove would even draw with four nineties.
