Our house is about 1500sq ft.... a hundred and thirty years old with the original windows (drafty!!). A few years ago we installed a mid sized Vermont Castings woodstove..... best thing i ever did. We have burned a good six cord per winter for the past couple years. I have saved a small fortune in heating oil, but have re-invested in my firewood operation. I figure i'm close to breaking even now. Seeing as i don't believe in paying for wood, i'm always scrounging it wherever i can. This has led to a new splitter ($1300), a larger truck (well... i needed one anyway $0), i nice used #7000 dump trailer ($2200), four chainsaws ($1600), all sorts of comealongs,timberjacks,wedges,mauls,sledgehammers,etc ($500),Personal safety wear($350),chain grinder(sharpener) and extra chains for the saws($300)..... not to mention the cost of the stove and having the chimney lined. BUT HONEY..... LOOK AT THE MONEY I'M SAVING !! Anyway... a guy's gotta have a few tools, right?? I currently have enough wood for this coming winter, next winter.... and part of the next. Good luck !!
