Through 30+ years of heating with wood and three previous stoves, I've never much worried about moisture content. If the wood was cut and split and stacked in the winter and seasoned through the spring, summer and fall, it always burned well. This is the first stove that seems really sensitive to the moisture content. I have some wood that is two years old and it definitely burns better, although it burns up a lot faster. I found that mixing one- and two-year-old wood seems to works best for me.
An update on the damper, it works great and significantly increased the heat output of the stove. Also, the wood lasts significantly longer, all things you would expect from a damper. I also like being able to open it before I open the door of the stove, which lets any smoke clear the stove first. There is a reason stoves have had dampers from the dawn of time.
As to the fans, they are still the biggest disappointment. They don't move enough air for one. Worse, as the winter has gone on, they have gotten progressively louder. I'm thinking it is because they inevitably suck in ash, since the folks at Jotul foolishly decided to leave off any kind of functional ash lip. I try to be tidy, but when the stove burns for days at a time, ash is going to get sucked in. Anyway, I expect the fans are suffering from this. Also, I noticed when the stove was being installed that the fans are very loosely mounted, held in place by a single screw. I mentioned at the time that I expected they would rattle, and they do. And because there are two fans, which unavoidably turn at slightly different speeds, they get a harmonic vibration going between them that makes its own rattle. Really annoying.
I expect over the summer I will try to find a powerful well-made single squirrel-cage blower that will fit the space. I'll let folks know if that works out.
