We've burned cherry for quite a few years, though less of it now than in earlier years simply because we've cut just about all we can get a truck to on our place. It burns well but I do have one complaint about it; that would be its more prone to create creosote than many other woods.
Now this - and I don't give it so much as a suggestion as I do something that you just might want to think about. My wife has a regular 'girl's lunch' that she and some friends of her's do the second Tuesday of every month. Its regular as clockwork. So I let her set my clean-out schedule. When she leaves I put on a pair of gloves, head up on the roof, and take 3 minutes to push the chimney brush up and down a couple of times. I then get down and spend another 2 minutes cleaning out the fallen creosote from the clean-out bin. Once a month, every month. Needless to say we never have a problem with creosote buildup so we don't fear chimney fires even on the coldest nights when the fire roars.
