Not sure if any members are serious wood burners for heating their homes. I came across this chart of BTU values and thought it was interesting. Our winters a fairly mild in NW Arkansas but I still burn 4-5 ricks of hardwood each winter. That's a 1-1/3 to 1-3/4 cords in yankee terms. Enjoy cutting, splitting and stacking. Kinda a hobby that gives me a little exercise. Wife, cats and the dog tend to gather around the fireplace on a cold night.
