Two diferent things Joe.joeq wrote: ↑Tue.

I'm not sure about the coal capacity comparisons of the 2 stoves, but wondering about the potential differences in either heat out-put, or burn times. Not compared to each others, but from OEM, to their modified states. Pauls would be a little more accurate, because he's been running a while, B4 the mag install. But because Scott has had the extended barrel from the beginning, might be a little more difficult to compare.
I would assume the extended barrel would be good for better heat/room transfer, and Pauls mod would benefit more with longer burn times. So I guess the 2 mods aren't a good comparison, because they're both accomplishing 2 different objectives.
Scott increased the heat radiating surface area of his stove to extract more of the heat being generated.
I increased the fuel storage area inside my stove and reduced the tending time needed. One benefit MIGHT be that it increases the barrel surface temp by pushing the hottest gases closer to the barrel. I've yet to see clear proof of that, but it's early goings.
What I have seen is my stove tending time is about 1/10th what it was without the mag. And there is no wasted heat output requiring recovery time. It was about 5 minutes from dampers opened to dampers reset, including ash shaking, empting the ashes, and topping off the mag again.
If I had two ash pans and only had to swap them, I could reduce that dampers opened to dampers reset time even more.

) it used half of a number 17 antique coal bucket. That's about 17-18 pounds of nut coal. And as you can see in the picture, the mag was not empty. I'm guessing by that, that I could have waited until about 12 hours passed to ash and reload the 20 pounds of nut that the mag holds.
