I don’t know. Each year, my dad and I bring the chainsaw before November, fall some dead pines and cut them into logs. We either split them into firewood that evening or the next day. That’s enough for around 3 months of winter (center of Spain, cold, but almost never below 0C and never snows).

We don’t split the, into very small pieces, some logs we don’t even split as they fit into the fireplace in one piece. We don’t look for the highest girth, but for what’s more practical, yearly fires kill enough trees for that.

My experience is it takes 100 hours to buck, split, haul, and stack the 7 or so cords of wood it takes to heat my house. A cord is 4 feet by 4 feet by 8 feet. The total time includes time it takes to sharpen the saw, and time it takes for trips to the gas station for gas for the saw and the splitter. Time for replacing the handle on the maul or the oil in the splitter is extra.

But that 100 hours is using a hydraulic splitter. Hand-splitting using a maul takes several hours longer. But it keeps you twice as warm: it heats you once when you split it and once when you burn it.
