Yeah, I've seen that particular chart before. It has Doug Fir at 26.5 (Same as Honey Locust). I have burned alot of Doug Fir I dont think it is that high on the BTU charts, most other charts have it at about 21 http://firewoodresource.com/firewood-btu-ratings/
I bet a local college has a more accurate BTU of the local woods than the charts. Big swing on some wood types for sure. "You burn what you got"
Definitely. Burn what you have. At the cottage up north, there is some red oak, but otherwise the best and most obvious choice is red pine. Down here at my house I have a lot better choices.
Found another maybe more realistic 19.3 mill/cord 20% moisture, 85 cubic ft/cord: http://www.engineeringtoolbox.com/wood-combustion-heat-d_372.html
I know I will never have the burn times that burning oak produces. But with some tweaking I've had all night burns. Most important to me I can keep NG bill small. Keep the house at a toasty 78 inthe kitchen and stove room and 69 rest of house. Only one thing is better than wood heat.
If you weren't galavanting around the country on that bicycle you would have had that wood up in there already.
confuse BTU ratings even more : http://www.hurstboiler.com/biomass_boiler_systems/heat_values_of_wood Different wood types = different BTU/pound look like we all could use some "pitch pine "
Exactly waddle. I get all night burns with red pine at the cabin in the lopi endeavor, but I save oak for overnights when I can.
still got doug fir at 26 alot of people reference this chart https://chimneysweeponline.com/howood.htm I think it may be somewhat on the low side with doug fir at 17 and lodgepole at 15 everything else is low as compared to other charts as well
Still burning from the 2 cord I put in the basement last April About thru it & will need to haul in another batch, about a week at these temps. ±2 cord: What's left, couple days in the wood box , few days along the wall.
Yeah thats the one I use as well. Birch and larch are 20/19.5 mbtu and fir is 17.4, lodgepole pine is 15.3. I recall dave, I and others chatted about the difference in charts a short while back and it was determined that different regions create different results based on climate and other factors that affect growth. Also an old growth tree versus a second growth tree is deemed to be denser. Still messes with your head though. For me I guess it doesnt matter the btu of wood since I can only burn what I have here so I know that birch is slightly better than larch and fir is slightly better than lodgepole and all I can do is drool over wood like locust or oak.
You know Dave; I don't know if it's intentional or not, but you're making a lot of "regular" wood burners look real bad with all these beautiful, pristine, organized pictures that you post!!! I starting to hate you for it!!!
