    Its a great quick resource and gives a good idea of heat source on a stacked level. I see other charts and others have different numbers churning out some noticable discrepancies (no fault to the author!) Just wondering why a few are different with BTU's.

      It seems that everyone does their own studies. I did my best to average all the work done by others, which basically gave me a larger data pool to source from and allowed me to add species that weren't necessarily on all of the lists.

    Once again Adam rocks the forum! Yet one more reason for all wood burners to be a member of the best forum on the net! Sortable PLUS drying times what more can a wood burner need from a firewood chart?

    Due to all the variables the drying times listed may or may not be what you personally experience.
    The drying times are a great relative chart when comparing one wood to another.
    Good job!
