Wood Burning BTU Chart

Some of the most common trees Million BTU's Chart

Why you need to know wood species

Oak contains about 25 million BTU's
Cottonwood contains about 14 million BTU's
If a cord of wood cost $200.00 and you get Oak you get twice as much heat as if you were to buy  Cottonwood. this is like buying 500 gallons  propane but only getting the heat from 250 gallons therefore cottonwood should be half the price of Oak

Good Wood and very abundant

  Russian-olive 23 I give this wood 2 years to season when first setting
out to season  you need to give it a lot of air or mold will start to develop.
Cut split and pile, stacking after a good summer in the sun.
Some say the wood has a stink when burned, I found after 2 years in the pile its a good burning wood with mild wood smoke smell.
I have used the wood for cooking it gives meat a nice mild smoke flavor.
Will be trying it in the smoker this winter.
Some small pops with small sparks. not many.
