people have asked about having to burn not totally dry wood. Just for the heck of it I took a 20" round of hickory I cut last winter, been sitting outside. Split off the sapwood and split out a section of heartwood which weighed 11#. Hickory heart is 80% moisture by wt so if it was totally green it should dry down to 6.6# Set this pc in behind my wood stove and after 3 days it was down to 10#, another 5 days and down to 9# but little change in the last day and it was -4 last night so stove was a little warm. I'll keep drying till it reaches equilibrium which I don't think is much more. Bottom line, my conclusion is that if you are short on dry wood, splitting some dead wood pretty small and getting it into a heated area for a few days will make a dramatic difference in how it burns. Yea, I already knew it but I wanted to quantify it. And I was bored! lol
