Coyote,
I admit that I burned some obviously wet wood in our fireplace earlier in the season. However, I haven't done that recently - my wife put a stop to that. She's got a good head on her shoulders. Also, I was not burning a hot fire daily; I was keeping the combustion air supply choked down all the way. You guys have made me see the error of my wicked ways.
I don't really know a better way of verifying if a piece of firewood is seasoned than to use a moisture meter. From what I have read, 20% - 25% moisture means the firewood is seasoned. Please correct me if I'm mistaken. That's also the moisture range recommended in our fireplace manual. In addition, I have read that if the wood is significantly drier than that, the logs will burn up too fast.
Yes, it is commonly thought by lots of people that wood will not season until the tree is cut into firewood lengths and split. However, I've never read about anyone's actually testing that theory using actual data. Well, in my case, that theory doesn't seem to be backed up by my data. I'm just stating my findings.
Anyone who has spent much time in the woods has seen dead trees off the ground that are dry as bone. Obviously, cut and split firewood should dry faster than uncut wood. But that doesn't mean uncut wood will never season; it just may take a little longer.
The trees I'm cutting up and burning were stacked off the ground on our log pile 2 1/2 years ago. We are reading 20% moisture content for both hickory and poplar firewood that was cut, split, stacked, and covered about 2 or 3 months ago.
You can draw whatever conclusion you choose. Basically I have learned that people will believe what they want to believe - and I'm not really any different.
After we clean our chimney, I have no qualms about lighting a nice hot fire, sipping some hot tea beside the fireplace, and enjoying reading people's comments in this thread.
Best regards,
Obed
