One thing that I've observed and heard a lot from other woodburners is that newer stoves tend to be far more fussy about dry wood. I can run whatever I have in my old Defiant by mixing dry with not-so-dry. But my Pacific Energy Vista won't tolerate that nearly so well. Dry wood burns, other wood really doesn't want to. So I'm wondering if we're comparing apples to apples here? Obviously I'm an older stove fan, but in fairness it should be noted that there's more to it than EPA or non-EPA. Newer stoves seem to require a stronger draft than many older ones too, so that can make it seem like the stove is the culprit, when it may not be. Just a few thoughts...
