Is this terrible firewood? I got a truckload for free, so the price was right. Edit: I have been burning mostly walnut this winter. I found this BTU chart http://www.thelograck.com/firewood_rating_chart.html Ranks sweetgum just 1.5 BTU's under walnut. I have never used sweetgum , so from what I get from online research is to split now with a hydraulic for this coming winter, '14, or it will rot by the next year. I have 4 cords of 1-1/2 year seasoned oak, so it looks like it will help get me through next year and allow the oak to get to premium status.
