This one has Euc listed at 33-34.5 Million BTU/cord http://www.consumerenergycenter.org/home/heating_cooling/firewood.html

Taken from the another site, the 5th post has a list of species with different Euc species listed instead off just the highest BTU type. here's the link to it too http://www.fornobravo.com/forum/f2/alder-maple-firewood-2543.html

This one doesn't list the BTU's but rather the density of some common and uncommon species. Sorry Euc isn't on there. With a little extrapolating of values a persons could build their own chart from species of known values. Its in alphbetical order. http://www.thechimneysweep.ca/8firewoodchartw.html

:cheers:

thank you.
 
The rated cordwood BTU output , supposedly , is for air dried wood with a Moisture Content of 20%. It wouldn't matter if it was air dried or oven/kiln dried as long as the MC was the same between samples.

And you are correct, burning green wood doesn't release as much useable heat to the house. Reliable charts will usually list the MC in the footnotes. That might be why there seems to be some diversity in the charts. One might be rating the BTU's for oven dry wood while the next one rates air dried wood. I've seen Ash listed at 20MMBTU per cord and seen it elsewhere listed at 26.4MMBTU per cord. Which one is right ? Experience tells me the Ash I've burned wasn't as good as Mulberry or Red Oak. Depending on the chart Ash might be higher, or Oak

Here is another one.

They all seem to range between 6,000 and 7,000 BTU/lb. So, the average is about 6,500 BTU/Lb, irrespective of species. I'm tempted to build a spreadsheet from the above link to provide an exact figure.
Ed, how do YOU spell Eucalyptus ? I couldnt find it on the chart you provided anywhere. :dizzy:
