looking at these radiators, I guess it would be beneficial to run the stack temperature high? Say with an MPD wide open? My stoves pipe runs directly out the back through a wall thimble to the outside. Am I missing out of some possible extra heat? I was under the impression, the less 90* turns in the run, the better the draft would be. But I can also understand how the internal black stove pipe would provide a little extra warmth. Not sure where the trade off is.

Joe,

Can you check the pipe temp right at the thimble and see how it compares to someone's with the same stove, running at about the same temps, but with a longer pipe ?

Many of the older stoves with long internal flues, and longer runs of stove pipe, can get into the five to one ratio and higher, of the stove's hottest outside temps to the stack temps near the thimble. Not sure how close the newer stoves regularly get to that, but comparing that ratio to similar stoves would give you an idea of what yours can, or can't, do with more pipe.

Paul, my heat exchanger temp is running 500* right now. And my stove pipe is at 100*. In this pic you can see where the thermometers are. The black one on the stove pipe is not situated there anymore. I've moved it more towards the back side of the baro, or closest to the thimble Naturally it runs cooler there. When it was mounted as the photo shows, it would run hotter when the MPD was closed.

The heat exchanger acts somewhat like these radiators you guys are talking about. But once again, if my stove pipe was running up the wall, "inside" the house, would I be extracting more heat out of this set-up?

Joe,
About 5:1 and the stack at about 100, I'd say your doing very well at heat extraction. And, . . any better and it may not work. :shock:

Don't forget that if you take too much heat out of the stack, the draft can suffer. Then it gets counter-productive, . . and even possibly unsafe.

Wow!!!! I googled dumb stoves and some of those things were unbelievable works of art. As to using one of those things and have it effect your stove efficiency that is not the first thing on your mind when you hook one of those things up. Burn it hot and get that draft going because you want high stack temps going to the dumb stove where it will give up that heat.

Another concept from our forefathers lost to time.

Yeah you're right Larry I saw one that looked like George Washington I would imagine if you could find one like that for sale the price would be high
