Wood Doctor, sounds like she is switching from wood to oil. Now has no need for the wood so she's selling it, using the money to put towards heating oil. Lots of people switch from wood to oil for lots of reasons. Maybe the old wood burner was done and needed replacing, maybe got tired of neighbours complaining of smoke or worse yet maybe laws changed and no wood burners allowed. Lots of talk around here of owb's being outlawed.
I burn wood but have electric backup, if I had a smaller more efficient(newer) house it would likely be cheaper for me to heat with electric than wood. I have 10 acres but no wood on the property so I buy all my wood. Lots of people burn around here (country) so free or cheap wood is pretty scarce. If I were to add up all the money I have spent on wood gathering, burning, loading, hauling, cutting and storing things in the last few years my wife would kill me.
Several chainsaws (6 or7), L35 Kubota, 2 trailers, 2 wood stoves, 2 chimneys, 4 different buckets for tractor, 3 wood splitters, lots of loads of logs and of course all the small stuff like fuel, oil, chains etc. Damn now I'm starting to wonder why I buy wood. I'll have to take pics sometime.
