It takes me up to a good six hours including sometimes a 15-40 mile round trip when I go out for the purpose of cutting and bringing home and stacking enough processed wood to heat my house and shop for one week. That can get into two chains, expense of driving, half gallon of mix, you know depreciation on the stuff, etc. Broken maul handles so-on. I like driving my truck so that's just a trip to the woods. The OWB is paid for twice in saved heat over 13 years. I get all my wood from tops I leave behind logging so access is free and it makes farmers happy.
What's the cost/benefit though if you value your time and expense monetarily vs. purchasing wood, oil, coal or gas whatever is in your area?
I get wood free so my cost is fuel and time. We burn about 4 cords a year.
I have a diesel truck that is pretty fuel efficient. I rarely drive more than 20 miles one-way for firewood. Lately I have scored wood from arborists that removed trees. I pick it up on the way home from work. If I fill my truck and trailer I can haul around 1.5 cords per load. To be conservative let's say I average 10 MPG loaded, truck and trailer. This is very conservative because I average 20MPG empty. I'll say 40 miles one-way or 80 miles round trip. If I bring 4 loads home I burned 32 gallons and at $4/gallon (high) I spent $128 in diesel.
I'll be conservative again and say $50 in gas, 2 cycle oil and B/C oil. I'm up to $180.
I bought a pile of chains from a dealer that went out of business a few years ago. They were demo chains and all were only used once or new loops. I paid $4 each and have a minimum of 6 loops for all my firewood saws but one. I file by hand and buy files in bulk.
I buy clothes for outdoor work I probably wouldn't if I didn't heat with wood. I have safety gear like chaps, safety screen glasses and hearing protection too.
I split with a maul and found a local hardware store chain that gives a lifetime guarantee on wood handles for my two mauls. I can't believe they exchange them but then again they made up the rule not me.
I never bought a piece of power equipment new. I either bought my saws not running and fixed them or used. I have an old log splitter that someone gave me because the engine threw a rod. They asked me to haul it to the dump. I brought it straight home.
I figure it would cost us around $200 - $300 per month to heat our house. I think I am way ahead.
Now for the benefits that are hard to quantify.
I am a mechanical engineer. I sit at a desk and work on the floor when they need me. We have a gym at work that few take advantage of. I go daily. The trainers ask me what my goals are. I tell them I want to spliit hard oak all day. No one seems to understand. I lift weights and run every day to stay in shape for firewood season.
I pass physicals with flying colors. An engineer in my industry did a study on retirees. The average aerospace retiree collects 9 pension checks. Cutting and splitting wood keeps me active, helps me relax and burn off stress. Plus there is nothing more peaceful then standing out in the woods, in the beauty of nature with a 90cc chainsaw screaming wide open in your hands.
I know how to do things others where I work don't. I fix broken machines with my own two hands. I don't pay people to work on my house, cars or equipment. I have skills that are practical that I can and do use every week. I love rebuilding saws that were straight gassed or run lean. I sell saws I don't want or need. I may or may not have a problem collecting chainsaws (CAD) so pretty much all the money I made rebuilding saws went back into saws. - but I can quit anytime, honest.
I grew up with wood heat in Illinois and I plan to bring up my two boys the same way. At 6 and 4 they help stack wood as much as they can. A life outside doing things in the yard will be so much better than TV and video games.
I can't put a price on these things. I know am ahead financially heating with wood and the savings has only grown with the passing years. As far as I am concerned the benefits I can't quantify far outweigh the benefits I can.
