I still think you are misunderstanding people when they are talking about their savings from heating with wood and your last post demonstrates the disconnect. Look at the words in bold.
When the vast majority of people talk about their savings they are talking about the savings from the entire process from felling to putting it in the stove. You however, are making a big deal about the savings related to the very last step (putting it in the stove) vs selling it. You are ignoring the rest of the process. That value of the wood is the value created by the rest of the process and it isn't appropriate to subtract it out when valuing the entire process.
You HAVE to put a dollar value on the "rest of the process" which you are not.
I think THAT is the disconnect. As you feel your time and effort to cut all of that wood is only costing you the few bucks to run your saw. And the labor you are just chalking up to exercise.
Its easy to assign a dollar value to the "rest of the process". Its whatever the wood is selling for in your area. Weather that be delivered, delivered and stacked, or the customer picks up.
Money (dollars) is just the medium.
Weather you cut wood to burn, or to sell......at the end of the day you are ultimately trading wood for heat. You choose the direct approach of burning 6-8 cord a year.....which directly heats your house.
I too trade wood for heat. But I first trade wood for dollars.....then trade dollars for heat. But the same end game.
Not directly YOUR numbers, but just some random simple numbers to illustrate.
Lets say you cut, split, stack, and burn 10 cord of wood a year to keep warm. DIRECT cost to you is maybe $100 a season for consumables like saw gas. You think you are doing great because it would cost you $2000 a year to the power or fuel company to keep warm. So you assume you are saving $2000-$100=$1900 by directly burning the wood. And justify doing so because....man thats alot of savings.
But reality check. Do the EXACT SAME WORK of cutting splitting, and stacking that 10 cord of wood. But rather than burn........trade it for cash. Lets say $160/cord (prices in my area). Take out the same $100 worth of consumables and you pocket $1500. Throw another $500 with it and buy your heat.
So are you "really" saving $1900/yr? or is it closer to $500/yr savings. BIG difference. Thats my whole point.
And with regional differences, these numbers can be all over the place. You might be able to heat your house on $1000 worth of wood and would cost you $3000 for another form, be it electric, fuel, etc. Or you might be burning $2000 worth of wood when $2000 worth of gas would have heated your house just as well.......yet you still think you are saving $2000 because you are not "directly" paying for your heat.
I find it hard to believe there are THAT many people saving THOUSANDS AND THOUSANDS heating with wood. Pre-Geo at my house I had 2 options. Wood (6-cord a year....value $960). Or baseboard heaters at ~$2000 per 6-month season.
I "actually" saved just a tad over $1000/yr in the 2 years I burned. Certainly not the $2000/yr that it would "seem" on the face of it.
With so many people claiming they save $20k+ over 8-10 years.....I find that just a tad optimistic......and feel there is more to the story and those arent accounting for the value of the wood, had they choose to sell it instead of burn it. Because that value ABSOLUTELY needs to be factored in if you are gonna boast about how much you save burning wood.
