Our teenage son will do it when told to but only when told to. He cuts, splits, and brings in the wood with me but, he's a typical teenager that will try to cut corners to save his precious time. He and I aren't bothered by the cold but, my wife wants it atleast 65 in the house. I'm heating with a Jotul 602 also. It works best with oak, ash or hickory. I've fit 18" sticks in diagonally when my eyeball calibration was off for the cutting.
Most of us burning wood are financially responsible. A cord of hardwood burned in a decent woodstove is equivalent to 200 gallons of heating oil. Thats about $800 these days. It also keeps the house warm when the power goes out. If you cut your own wood, it also justifies getting a big tractor.
