Some of you longtime members may remember a few years back when a big, old hard maple in my front yard died and had to be taken down. Naturally, I reduced it to firewood in short order ("don't bet against me when it comes to firewood" I told my incredulous neighbors). Stacked it for a couple of years and now I'm finally burning it. It seems to burn a lot better in my boiler than the beech that I've been burning all season. I've noticed that the maple burns really hot, leaving this fine, white powder instead of the more common gray, granular ash. I don't know if there's something that sets hard (sugar) maple apart from the beech, which is also pretty dry, but it seems to be the perfect food for my EKO. The vast majority of what I cut and burn is beech, and that won't change. But I do cut some maple, and moving forward, I think I'll segregate it as much as I can so that I can use its fine qualities to my advantage. Maybe as a superior fire starting wood. Another nice thing about maple vs. beech is that the maple has thick bark. This actually results in less solid wood per load (it adds up over time when you cut and haul 20 full cords per season like I usually do), but it also makes really good kindling/firestarter when dry. The beech has very thin bark that disintegrates when dry.
