BK has a similar video and capability of burning huge logs but I found that it’s really tough to fill the firebox with those giant splits so you actually get less fuel in the box that way.
I was telling a buddy of mine just the other day that with my smaller stove, I found myself bringing the wood to the house last winter and before I brought it in would split it down some more to get a better fill in the stove. I found it to run pretty good. But it is nice to be able to find yourself frustrated with a particular split and claim "that's an allnighter" and be done with it.
The solution is a mix of split sizes to pack the stove fully but when I split several cords in one day I find it very difficult to vary the split size. You get into production mode. I do like getting a big hoss in there when I can.
I've found big chunks stone cold and still there in the morning. What good is that ? A good ratio of surface area usually makes the best fire and burn rate. Plus probably makes for an efficient burn as well. In these days of the woke wanting to save the planet by any measures necessary I can't see promoting poor burning practices.
I don't think using big splits is a poor burning practice. It's just not the best way to get the maximum fuel charge so your burn times suffer. If your fuel goes out before burning then I would suspect your fuel quality or draft settings. That big split was probably still wet in the middle.
