Ash. White Ash: 3689 BTU's Black Walnut: 3120 BTU's or 84% as much. And besides, a "Kiss my Walnut" t-shirt just sounds wrong.
No. Ash has a bit more BTUs. 22 mbtu a cord vs 16.9 mbtu a cord for walnut. So ~25% more BTUs for ash. Ironically, black walnut leaves more ash in the firebox, than ash tree wood does. Also, ash typically dries faster than walnut.
Those are odd numbers. Typically they get rated by million BTUs per cord. All of the BTU charts I know if list ash around 22 mbtu and walnut. Around 17 mbtu a cord. Maybe you are looking at the weight of a dried cord??
Lb for lb yes but some btu’s are merely a guide. This isn’t a standard for how it burns but how much heat it produces. There’s a disparity in burning certain woods that have low and high flames. Most often flames of hot wood aren’t very high at all but produce a much more powerful effect of heat. Burning locust has this effect. Not to derail this but if you compare locust to say cottonwood, both are hardwoods but cottonwood will burn with a high high flame most of the time. Locust just has a low to medium flame but once its going its very hard to stop. Being said I’ve never burned ash, just some walnut and that’s about it. Nothing TOE UP about it, it’ll keep you warm for a small amount of time but not gonna break any heating records.
Yes, I was in the WRONG COLUMN. And yes, I was looking at weight. 23.6 Mbtu's for Ash, 20.0 Mbtu's for Walnut. Here's my source: World Forest Industries. Thanks for catching my error. Much appreciated.
Ok... You win. Maybe. But is this a challenge? If you're going to go there, how about "Can I Smash Your Ash with My Walnuts?" With a name like Tiger's Wood, and if this is a challenge I'll expect you'll be back to one up me, him, and everybody else. And, I actually was in a Tiger Wood commercial, filmed at Bandon Dunes - right before the SHTF for him.
I prefer Ash, but get very little to burn. There are tons of Black Walnuts around, and the sawmill can’t give away his walnut slabs. The Ash I do get takes a few more months to dry out than walnut, but both dry by the next season
Ive never had ash, it doesnt grow here for some reason. Walnut is okay, Ive had cords of it in the past as some huge trees got taken down on some of my construction sites. It has a great purple and blue flame.... however its dirty pre burn, the bark is nasty... and post burn its dirty too as it has really heavy and puffy ash that some how floats out like snow when you open the door.
I wont turn down ash... But I've never been really impressed with it... I still love working with Walnut and burning it... But I'm good with being a bit off...
Ash dries faster, splits easier, and produces more heat. Walnut is ok but I found I had to add wood to the stove a bit more often than with ash.
Ash for sure is one of the best for firewood (don't bash my ash for this comment). Sure there are others that are higher on the chart but it really is hard to beat ash as it grows nice and if the tree is in the woods there is not a lot of limbs to tend with. Wood cuts nice. It splits super easy. Dried quickly because it starts out with a lot less moisture than most other wood. It also burns very nicely. Walnut can be okay and if that is what you have to burn, burn it! Yes, there will tend to be a bit more ash from the wood but that is not a big deal. The wood certainly can be pretty.
I will add this, was just cutting a load of red elm and hickory a couple of weeks ago. I needed another 1/4 of a truck load to round out the load. I had a big walnut log a few steps from the truck I could have sliced up or cut ash in chunks and carry it out closer to the truck. The ash came home with me. I think that gives my answer.
X2 ^^^ I like BW for woodworking, and Ash for my stove. But you burn what you've got available. Our lot is primarily Maple/ash, with some shag hickory, hop hornbeam, BW, pine and hemlock thrown into the mix. I'm a big fan of ash in the stove, and with EAB, I'll be using it for some years to come.
