I have a little wood stove in my fairly big shop. Heating needs in SW Indiana are pretty minimal, but I like the shop warmed up to at least 50-60 degrees to work. My wife loves a fire in the winter so she'll come hang out in the shop, AND she splits ALL of the firewood "for exercise". I do have a tractor mount hydraulic log spliter, just needs to have the spool valve rebuilt, but I hate to deprive her of all that fun. I do have a NG "Mr. Heater" furnace in my shop, got it hung and chimney installed, but never got the gas line from the house hooked up after I cracked a rib in the attic putting in the class A chimney.
We have about 15 acres of hardwoods. The deadfall is enough to keep us supplied indefinitely, and plenty of that goes to waste, left to rot in the woods. Lots of huge oak and maple trees. Some walnut too, shame not to haul that to a sawmill for woodworking projects but I have plenty of seasoned walnut. Now if any of the decent sized cherry trees go over they will get turned into lumber, I like cherry for woodworking.
Last winter we mostly burned sassafras trees. Had to cut about 50 small diameter trees (10-12" at base) out of the backyard immediately behind the house. Laurel wilt, caused by a non-native beetle, wiped them out. Sassafras burns hot and fast, makes good kindling for starting a fire, but not a good heat source as it goes pretty quick. We've burned huge piles of it in bonfires, just too much to split and store. (Burning is recommended as a way to slow the spread of laurel wilt).
I enjoy small doses of cutting, splitting, hauling and stacking firewood. Did a LOT of it as a kid, having grown up in
@cathead's part of the country with two woodstoves as the only source of heat for our house. With 6 brothers and sisters, stacking huge round piles of firewood was a family chore, usually fairly fun with all 9 of us working at it and went pretty fast. IIRC we went through about 5-6 piles a year, each pile about 8' diameter and 6' high. I'll let those so inclined to convert that to cords of firewood, mostly birch with a smattering of poplar as that was the respectable firewood that grew in St Louis county, Mn. I have resorted to a power sharpener to touch up chainsaw blades when a few licks with a file will no longer get things uniform and sharp. If you're burning ethanol fuel in a chainsaw without fuel stabilizer and manage to not gum up the carburetors, I want to know your secret. (Running the saws weekly doesn't count, I'm not that ambitious!) I do fine with the fuel stabilizers but that was a challenging lesson when ethanol first become commonplace.
