That doug fir will be great and if you have it split and stacked already that wood will be just fine this fall. Those small logs are already fairly dry.
Most folks in the NW love the doug fir (aka red fir east of the pass). I envy your log load and price and if I could get that deal, I would take it here even though I have a 15 acre woodlot of free wood to cut. How did he unload that truck? Was there a grapple on the front?
I too have burnt willow, cottonwood, pine, red cedar, doug fir, and red alder in the BK and other that the low ash quality of the doug fir and the high ash of the cottonwood, it would be hard to tell the difference in burn times or heat output.
Thanks again for the feedback. All this information is helpful. Out of curiosity, why would you want to buy wood if you've already got more than you can use? Just the blow-down on 15 acres would seem far more than enough to heat a house with a Blaze King.
