( Pretty much any woo dhas the same btu content per pound so as long as you are buying it by the ton, it shouldn't matter as far as cost is concerned. )
Well, not exactly. Attached is a little chart that will give a better explanation of the btu's available in certain woods. Besides some of the soft woods, like pine, being undesirable because of the creosote they will build up in your chimney, the moisture content is important. If you are buying wet wood, you are paying for water. Basically all water in the wood must be heated to 212 degrees for it to boil out; this produces no heat. Only after that moisture is gone does the wood start to break down, creating fuel gasses, which is at just over 500 degrees.
- That chart's last column just calls out "units" required to make 1 million btus. That chart maker gets an F. What unit is being referred to? Once complete, that chart is great for cordwood. Doesn't really work for pellets since the moisture level is controlled and the pellets compressed to a consistent density. The chart is dependent on density inherent in the cordwood.
