Allen:
In 35 years, I've bought three chainsaws, probably 30 chains, about 10 bars, a large indoor furnace, a good box stove, the outside furnace, built a splitter and a wood hauling trailer for the Cub. I have to clean the chimney, haul all the ashes and maintain the furnaces.
For the past 30 years, we've heated about 95% with wood, figuring between three and four federal cords a winter. Most years, the wood has been scavenged locally (meaning the 129 has hauled it from the woods), with the exception of three half semi loads (10 cord loads) and one local purchase of three grain trucks full of gnarly oak.
In the old days, I had help splitting, but for the past few years it's been pretty much a solo effort to cut, haul, split, stack and feed the furnace.. Money? - who the h.ll would figure savings?? - IT'S OBVIOUSLY MY HOBBY!!!!
BTW - I like a warm house and not having to depend on the power company in the winter (light that old inside Johnson 9900 up and gravity circulation keeps the place toasty).
