100 Types of Firewood Rated | accurate BTU ratings, what a journey

[boisafeudunord]

99% of BTU ratings you see online of incorrect for firewood. I decided to see if I could come up with BTU values correct for firewood, it turned into more, a lot more.

Enough of a journey that I wrote a blog post on how I came up with the data in my firewood ratings tables. You can read the blog post here:

The firewood rating tables holds data for over 100 trees, you can see it here:

Hope some of you find it useful!

Nice job.

Something seems off with the density and cord weight numbers. According to the table, most dry woods would sink in water. And, in the table, the weight of a wet cord is equal to the density of dry wood x 128 cu ft. If you compare the density of dry red oak, for example, to the weight of a dry cord, the stack would be 42% air.

I'll have a look tonight, somebody also mentioned something similar.

Hey guys, he did say it was a Beta...mistakes are inevitable and will probably be corrected.

Appreciate the effort!
The second link is not coming up for me, but maybe that's because you are working on it.

Good work researching all of that! Second link says it's down for updates.

Interesting.
We often have this conversation amongst us wood burning folks.
Thanks for sharing.

Yeah, there was some not quite right calculations that were throwing things off, taking me a bit to get it fixed Hopefully tomorrow.

Okee dokee, so I pretty much rebuilt the BTU tables as, as I went I found what I think are better ways to do things. All calculations / formulas are redone and improved, I found some better data to use as well.
I have also added a "Print" option. When printing it will print in standard black on white, otherwise I imagine it would use up an awful lot of ink.

The blog post explaining how I built the table, formulas, sources, etc has been rewritten, it is here: How I built my Firewood BTU Ratings

I spent entirely too much time on these tables but it was pretty fun when I was not pulling my hair out.

If you see anything "off" please let me know!
