Wood species type BTU values of a cord 
burning wood in a wood stove

You will get 86% of these values,
when using the newest GT-6000 EPA White Tag Boiler!

As you can see from the chart below, the famed red oak is not the highest on the list.

It is surpassed by 13 other varieties that have as much as 37% more BTUs per cord!

This can mean much longer burn times and less loading.
If you have this type of wood available (top 12 in the lst), save it for those cold, harsh Jan and Feb days.

Avoid Burning softwoods because of the very low BTUs obtained when burning and some softwoods
put out much more creosote. MIX when at all possible!
