Title: How Much Money Does Your Outdoor Wood Boiler Save You? w/ poll
Post by: userdk on August 12, 2017, 02:32:12 PM
    Did some digging and found this page on the official Wisconsin.gov website (http://www.stateenergyoffice.wi.gov/category.asp?linkcatid=3855&linkid=1845&locid=160). It indicates, among other numbers, that the average Wisconsin household heating with electric spent about $2400. An average water heater will cost an average household approximately $781 per year. From rough figures and miscellaneous articles around the internet, it appears that the average household with a swimming pool spends up to an additional $800 per year heating that(if they heat the pool). Even with the cost of an outdoor boiler rising a bit on average post-EPA, it looks like outdoor boilers may not be a thing of the past yet. Looking forward to this discussion. Comment below what you're heating and what it would cost without the boiler. Are you buying your wood or getting it free (http://outdoorwoodfurnaceinfo.com/forum/index.php?topic=9193.0)? How does that stack up

Ayuh,.....    I've been livin' in this old farmhouse that needed oil deliveries every 10 days to 2 weeks through-out the heatin' season,....
That's 'bout 150/ 200 gallons per delivery,....

I built my own outdoor wood boiler, 'n traded my labor for wood from a tree service,....

Since I fired my boiler, 'bout 10 years ago, I've spent Zero on heatin',...

That's many thousands of dollars, dependin' on the price of oil,....

Propane is my back up source of heat so it depends largely on propane prices. Over the 16 years I've ran an owb I'd guess the savings around $1500-$2000 a year. Less so on years like now when propane is cheap, but you get it back when prices rise.

Now, if you factor in the nice tractor I bought, the wood splitter, dump trailer, and the 440 Stihl, well..........
Might not have saved any money but its paid for some pretty cool toys in the process.  :)

Don’t really know, always had a wood furnace of some kind. After we got the natural gas at the farm, mainly for drying corn, the first real month of winter the gas bill was over $200, next month we turned the heat down to 69 and left it, still didn’t help much so went back to using the wood furnace in the basement. Newly married then and the wife spent a lot of time dusting instead of doing things that newlyweds should  ;D

So went to a fab shop a few towns over and bought a few sheets of 5/16” that had mill scale in the finish or something, can’t recall but they couldn't use it so they sold it to me at scrap price, took it home and laid a 5’x10’ sheet on the sawhorses and started laying it out, all was cut with a oxy acetylene torch as having a plasma cutter in a shop was unheard of back then, ground everything smooth and took it back to the shop and they bend it all for me, brought it back home and burned up a brand new 45# spool of .045 in the three phase wire welder welding it all up. Got it installed the first few days of February and shut the furnace off, about April Nipsco sent someone out to change the meter. Also got a letter stating all the penalties for messing with a meter >:D

So $400 for gas in two months with a cold house and a unhappy wife. Once the we quit burning wood in the basement all the dusting soon ended leaving time for better things, her nosebleeds also quit, air gets too dry and she’s guaranteed to wake up with a nosebleed. Still use the gas furnace once in awhile just to make sure it still works and on the odd occasion where you get a few real nippy nights but it just aint worth starting the boiler yet.

So, old boiler lasted 16 years, have been running a G series for two winters, so lets say four real cold moths each winter at $200/month x 4 x 18 = $14400 then another 2 months each winter with light usage so lets say another $75-100 each of those months equals another $2700-$3600 for a total of $17100-$18000 saved since I put the first one in. Course with the old I couldn’t heat the shop either so messed around with a lot of waste oil and the headaches with that, still use that as well but only in the shoulder seasons, light it once a day or every other day and get 600+ gallons of water up to 190.  I could literally turn the gas off at the meter in the winter if it wasn’t for the clothes dryer and gas range.

LOL yah, but she was always like “what if I have to goto the bathroom in the middle of the night”.

With the boiler we keep the house warmer at night as well.

I hate paying for something I can do myself, in this case why pay a corporation for natural gas when I have more than enough wood to cut.

I designed and built my house around the use of an outdoor wood boiler, so technically it hasn't saved me a dime.  However.... the background is that our old house, which is half the square footage of the current house, used anywhere from 900-1100 gallons of fuel oil every winter, depending on the weather.  Now, the new house is more energy efficient, but it's much larger, so there's a small trade off.  Let's assume that the new house might use 25% more fuel than the old one.  Probably a bit too conservative but whatever.  So 1000 gallons of #2 oil at $2.50 a gallon (again a reasonable assumption, based on historical prices in my area) x 1.25 = $3,125 per year.  This is probably a bit low.

Now, the old house was simple.  Automatic delivery, no hassle, pay the bill.  No problem (well, except for that "pay the bill" part...)

Today it's different.  Outdoor wood boiler means equipment for wood processing.  I don't buy wood, I harvest it off my own land and my parent's land, so there's no cost for me for the actual wood.  However, this has necessitated the purchase of a fair amount of equipment - a tractor and bucket loader, a log splitter, several chainsaws, wood and log handling tools (i.e cant hooks, log tongs, maintenance stuff etc.).  All told I've probably invested $15,000 in the equipment (although I use it for a lot of other things besides firewood).  The initial investment for the first wood boiler I owned was not counted because every house needs a heating system, so it was either spend it on a OWB or spend it on a gas or oil furnace.  The second wood boiler (my current one) was a $10,000 investment to replace the first one.  So let's say I've spent $25,000 over 12 years on wood heat.  That's about $2,100 annually.  If I had to buy wood, I'd get it in tree length delivered to my back yard and probably not need the tractor (but I'd likely still have some kind of ATV or UTV to do other things), I'd also be out another thousand bucks a year for purchasing the truckload of wood.  So, if I had to buy wood all this time, it probably wouldn't have saved me any money and I would have saved countless hours spent busting my ass outside in all kinds of weather, processing wood and feeding the OWB.

However, I still feel I've saved a lot of money over the years, because I have a really hard time writing that check to the oil company and I would rather spend 2-3 weeks worth of time every year gathering firewood.  Now that I have a new OWB and all the rest of my equipment is in good shape, now it's just the annual value of the BTU's harvested, measured against the depreciation of the equipment.  I tell my wife that I save so much money burning wood that she ought to let me buy a new chainsaw every year, but so far it's not worked, I think she's smarter than that.  :D  In ten years maybe it'll be time for a new tractor or a UTV or something like that.

Lol what you just said reminded me exactly of what I have going on!  I probably didn't save anything at all but went totally backwards and upside down.  Got me a bigger truck, dump trailer, new tractor and a few new saws. 75,000 dollars later I'm saving a few bucks on my heating bill over the winter ;)

Back during the winter of 2006, we were burning approximately $800/mo. of fuel oil. During the summer of 2007, Dad went into partnership with his brother Randy to buy a small outdoor wood stoves business from a friend that was moving out of state. We've never had the tank filled since.

What does a golds gym or YMCA member ship go for.
Then from door to door it takes two hours to ,change ,drive there ,sign in ,get the germ killer spray bottle,
Warm up, do the work out,cool down, Shower,sign out, drive home.
You are at the two hour mark. Usually you make it there 320 days a year so- 320x 2hr= 640hr of Un -productive time or  0- produced.
  I can cut down and process a half cord of wood in two hours talking 24" wood.  if I want a workout so with that I would have produced 160 full cords. In theory's mind. Then take into account Murphy's Law -30 cord. Then hernia surgery yup. Kyropractor visits. Break downs.
Kyropractor once told me he loves firewood. I asked what kind of stove do you have. He said I dont have one. Then I got it. Yea. Here's your money.

That's the calculation most people forget about, the value of their own time. Don't forget to check the increase of your electric bill by having multiple pumps running 24/7 also.

If a person is honest, it is more about the satisfaction of self sufficiency, not having to pay a heating bill or some other moral victory. In almost 40 years of burning wood, when everything is factored in, any savings are negligible.

But what else can you do that puts that kind of power in your hands? Oh ya, snowmobiling! Come on WINTER!

Post by: mlappin on September 02, 2017, 09:13:33 PM
Whether or not it’s negligible is what you’d do with the wood if it isn’t cut. We have 250 acres on the home farm, then rent over another 1000 acres, all of it has trees that need cut anyways, You can only shove so many into a fence row instead of cutting them up.

With the ash borer another mess arises, if they aren’t cut and just fall, eventually if your woods is heavy with ash you can’t get thru it anymore. I cut a hundred ash trees out of a four acre woods, still have plenty more, if all those fell that primarily came out of the east third of the woods, wife wouldn’t be able to mushroom hunt there anymore with out breaking her neck.

For sure a person needs to maintain their wood supply. My neighbor just logged off a 20 acre parcel with a lot of ash and I believe he got a paycheck around $17,000 and this was not clear cut but they took a lot of trees out.

How much I've saved?

No clue, but I do know one thing --- there is no way I could've maintained my current house heated up to the levels I do IF i was just doing it with electricity alone, period.

My house is very toasty during winters and that is solely because of the wood burning stove. Not a chance my thermostat would get any where near to the current settings if electricity was the source of my heat.

Besides, as mentioned a few replies prior; add in the fun to burn wood. The "free" membership to your own gym and the blessing of working out everyday at the leisure of your ow backyard w/o paying for it :)

Bring on the heat!

I figure heating with oil to a cooler temperature than I have the house now cost me around $3,500 a year.  I sell firewood and everything I burn at home is the junk that I can't sell.  I'm going on year 7 with my boiler which took 3 years to pay off.  I'm looking at around 14k saved so far and my house is toasty warm.  It also saves me hollering at the kids as they stand there in the dead of winter with the door open.

I used between 800-1000 gal of propane prior to my wood boiler install. I think the last propane I bought was 4 years ago. When I purchased my propane furnace in 2002, propane was selling for around $.89 / gal. I think it has been as high as $3 / gal since. So I compare my 1000 gal usage to 7.5 cords to calculate my savings. At $165 / cord for red oak and hickory, I need to buy propane at less than $1.20 / gal to justify its use. Plus it has to be purchased in lump sum in the summer to get that price. I can buy wood anytime for $165 / cord delivered. My pre-buy price for my propane this year was $1.53 / gal.

Times have been hard for my family during the Obama years, so currently it is financially difficult for my family budget to put down over $1500 on propane. My saving this year would be around $300 for using wood. Some would say not having to load a furnace is worth the extra $300. One thing I do with the wood heat is raise our temperature to 76 degrees F. Never did that with the propane furnace. 72 Degrees was the norm.

If I chose to cut a few trees on my 10 acres, I could save more. Seems like I always have at least a cord of scrap wood that needs cleaning up every year. Plus I like the pioneering feeling I get when I see the smoke. ;D

Not sure if it’s possible in your area, but I just sold a G100 to a guy that has at least a few years worth of wood sitting around, he owns 2 acres with maybe five trees on it. Anytime he sees a tree company working he stops and asks if he can have it. Most of the time he has to pick it up, a few times they dropped it off already mostly cut up. With the ash borer around here the county seat has been bringing him wood that they cut in different parts of the city.

It’s a win win regardless, he gets free wood and the tree companies/city avoids tipping fees at the landfill.

Thus far, and I've owned my OWB for three years, I've yet to ay for any wood. All wood used have been gathered free off of Craig List and as of today, I do have all wood needed for this coming season plus at least half or more for next year. Did I say free?

I was paying around $600/mo between LP and electric to heat the house to 65 and shop to 50. Before I broke my neck 3 years ago, the wood cost was around $100 a year for fuel and whatnot as I have 40 acres of hardwood right down the road. Now I buy it by the semi load from a local logger which ends up around $800 a year processed and I rarely need to even start the saw. So in theory I save $2700ish a year. But in reality, I spent $14k on a new system with installing it myself, $12k on a lean off my shop to house the boiler and wood because I'm too big of a pusscake to be cold while firing up, $3500 on a dump trailer, etc. Then taking into consideration the boiler will probably need replacement in 10-15 years, so then ya start all over. Realistically I don't think it saved me any money, but I can keep the house at 70 and shop at 60, melt my sidewalk and apron, take hour long showers, and dispose of all my empty beer cases. It's more the comfort and ease over the cost savings as far as I'm concerned.

Your just being honest wreckit87. Sometimes it isn't all about the money. I enjoy getting out in the woods, cutting in the spring and keeping me active now that I'm retired. There are still times when it gets old but that's what tomorrow is for.

I figure this year is my "free and clear" year.  We have a two story with two electric furnaces. We put a second story over a ranch home. First two years, would spent over a thousand a month on electric.

Similar heating bill is now about 150- 200.   I still havent installd the water heater unit.   I have my garage heater, am waiting for my brother to hook it up before firing up the boiler.  Figure keeping the garage at 40 or a little higher will help with a warmer buble for the bonus room above it, and for the living and dining area next to the garage.

We did a bump out on our kitchen remodel and added a four seasons room above the bump out.  Since we have the OWB, I didnt think twice about utilitiy cost.   We did five foor windows for a view of oyr pasture. I got the highest s.unlight blocking uv Windows available, and did a passive solar adjustment on the eaves. Less sunlight in Summer, more in Winter. My main goal is reducing AC cost. Heat is cheap.

Additionally, My lower furnace was installed in the early 70's.  I don't feel the need to update to a more enertgy efficient unit. Figure I am afew thousand paid into the OWB by never having to do that.

My neighbor who educated me on OWB has a double wide that he added a two story Branch Davidian looking thing next to it, was getting killed on propane.   Given the suprise attack fill up the tank without telling you program, he paid over five bucks a galln a couple times. Now, the only propane he uses is to keep the pilot light on the furnace.


I have ample wood at the farm, and have to cut anyway. Just had one fall in the weaning lot this week. Had a tri-axle of mill remnants dropped off to keep me ahead of the game for cutting this Winter.

I just love turning up the temp as much as I please.   Only worry is that wood hasn't burned down too low overnight. Got it down pretty good now, though.

around here it seems to cost about $3000 to replace an out of date oil tank. (10-20 years, depending on your insurance). Oil is about $1.10 per liter.
We have been heating two houses off our 80 acres for years and last year installed one used Portage and Main  to do both houses. $4000 for the heater, $5000 for the piping, my own little JD hoe. Each year in past we have burnt about 15-20 bush cord total in our airtites BUT
my wife and I are 72 yrs old, and  I'm undergoing chemotherapy.  We have an old friend for a tenant who  is out there twice a day feeding the dragon so we both have heat and water. His young sweety has a 14 year old who has yet to start a chain saw as he was raised in town.
Twenty year old JD compact tractor is currently in for its first major repair and when it returns it will either have the wood forks or snow plow, which ever we need at the time.
No plans for the nursing home yet.....and that is worth thousands$$$$
