I looked in 4 different firewood btu charts, and Catalpa is not listed. I found a ton of it on Craigslist. The person told me it was Catalpa. Is it worth my time to go cut up the downed tree and split the wood. I don't want to waste my time with crap wood. I usually only try to burn good hardwood in my wood stove. It's a small stove, 1.6cu firebox, so I'm fussy about burning wood with a high btu rate. Thanks in advance for the help.
