this year i sort of got caught low on the firewood. all this talk of "global warming"--geez i thought 12 full ricks was enough. --then i had to scramble in the dead of the winter cold to round up another 12 ricks.( six chords)


i ain't going to do that for 2010!


this year i am going to have enough for the winter --even if it is six months long like this year.

i got 9 ricks on the ground nearly all green wood. --i am thinking 25 ricks will be enough. so i only have 16 ricks to go! yea that sounds like a lot but al-gore is predicting another warm winter for 2010!--how much firewood are you folks getting for the fall& winter of 2010?

I get 20 "Ranks" Same as Rick or face cord. My guy charges $30.00 per. split & stacked.
I can't hardly cut my own for much less.(my back would not allow it anyhow) Chainsaw gas & oil, tractor gas & log splitter gas. This is enough for our house & workshop. We use plenty of propane also.
After 20 years in south Florida........we like it around 85 in the house!! Heh...Heh...

SHHH... don't tell the energy police!!!

All my firewood is white oak & the propane pre-buy this winter was $1.37.

I live in a VERY poor VERY rural area, and most things are way cheaper than areas where folks make decent wages.
Eggs 25 cents a dozen, Ground chuck $2.00 a pound, large candy bars 35 cents, etc..
Glad we retired before moving here though....No way would i keep installing carpet for $2.00 a yard.

I've reduced my wood use by about 40%. Have a stove now that has a 2 1/2 in pipe on each side of the fire pit that delivers fresh air low in the fire box. Where the ignition is taking place. It is very efficient. Empty ash every 4-5 weeks. Get about a 5 gallon pail full. If I can figure out how to attach them i will post a picture and a drawing. I've been burning for years and have never seen a wood stove that is this efficient.
Your fortunate with that wood price Brad, on this side of the state it is 60-100 a rick delivered.
I lined the stove with fire brick (1.60$ each locally), cut them to fit exact, they cut surprisingly easy with a chop saw and a masonry blade. Laid them up with a running pattern. Been using it for months now with zero problems. The fan behind it helps move heat throughout the house, aprox. 1300 sq. ft. No problem at all keeping the place at 72 degrees.

Sounds like a Tempwood stove.. Just a square box with two pipes on each side of the round fire pit top opening.
The pipes set into the stove with two flaps for heat adjustment.
They used too be made in North Adams Mass.
Adjusting the heat control flaps controls the air flow. Air feeds too the bottom of the fire.
Super super efficient clean long burning if adjusted properly.
Basic rule of thumb when we lived in Vermont.
When you think you have enough firewood. Chop some more. :)
Another great furnace is a wood fuel oil combo.
Kind of pricey but will save money in the long run.
Burns firewood and if you run out of wood, the oil kicks in too maintain temperature.
I told you too cut more wood j4. You did not listen. :lol:

I have usually burned about 20 face cord every year for the last 5 years. This year I put a wall up in the shop to cut down the square footage. I also installed a magic heat in the flue. I have about 15 dry cord of oak and ash stacked just outside the door and am staying in a nice 80 degree shop. The house is warmed by forced air and boiler heat so we keep that about 68 degrees. I practically live in my shop with all the comforts of home, just ask my wife or family.

current prices in this part of Colorado is around $200/cord for hardwood (not common around here), or around $100/cord for pine or aspen (common)

Many, Many scams based on 'truckload', or 'rick' are prevalent here... without actual measurements, it's like a box of chocolates... "you never know what you're gonna get"

Ash, I was looking at those too.
Depending on the size of your cabin, and building codes (if there are any in that area), they seem very efficient. But if you look into them more, most people using them are in fairly small homes and most of them are earth made houses. You know the hippie type in the north west. :D Another thing is the exhaust, most building codes require the chimney to be above the highest point of the building, if you make the heat exchanger to long it won't have enough force/draft to go that high.
Now to use the same principles you could make something similar, look up a masonry heater or Russian stove, it's almost the same thing but made of brick or stone and looks like a fireplace, the exhaust gases pass through several turns before going out the chimney or pipe. You burn them hot to heat up the masonry and that slowly radiates the heat.

Actually a steel/cast iron stove (wood or coal) can be turned into a mass heater, build up brick or stone around it to hold in the heat. And if you put a thermometer on the stove pipe before it goes into the chimney or exits the building and your getting readings over 300 degrees, you can reroute that sideways through a heat mass then turn it back toward the exit to soak up more heat.

I found info where a guy built a mass heater using a 30gal & 55gal drum, placed them inside each other so the 30 is the fire box, then he put masonry sand (crushed granite) between the two (this was the heat mass). He claims with a short hot fire it radiates heat for at least 6 hours.
I'm actually looking into doing something like this right now, the place I live in now is all electric heat and three months of the year the bill at least doubles and the rates keep going up, hopefully this will help a little and I can get wood fairly cheap or free.

Coils...

Yes.. Please. You are good with this picture talking machine.. You mentioned the Russian stoves. I read a long time ago about them.. They use them in Siberia, where wood is scarce and heat is life or death.
Rather complicated heat exchangers, but super super efficient.
Lessons learned from some cold winters in Vermont. Dont get a stove that is too big for heating your home.
You will have a creosote build up and the stove will not work efficiently.
Like our AC units here in Florida. Too big the A.C. cant do an air exchange. It defeats the workability of the unit.
Coils. See if you can find something on those Russian stove heaters. They build them with fire bricks, I do believe. But the efficiency of them is supposed too be incredible.
The stove Mija has, I have used. Excellent in my small cabin in Vermont.
Your project, if you decide too accept this mission. :cheers::)
Get info on the Russian stove.
I am going too be at knob Creek with BigAl, Bluejack and 555th this spring. Come hell or high-water.
Looking forward too meeting you and the guys.
I want my picture with Bluejack and his autograph. :)

Oh and like that stove Mija has, look at this one a guy did with a barrel.

The first two links are basically "nice" versions of the 3rd world rocket stove mass heaters. I'll probably go with the nicer version. I always wonder why people don't allow for air from *outside* for combustion air, it makes the most sense. Why would you pull air from inside to burn and force cold air to be drawn in from all the cracks and so-forth. Not to mention cold air is denser, more oxygen, for a hotter burn.
And for code in northern Michigan, in the woods (the big woods), it's pretty lenient. As long as I feel good (as a licensed builder and licensed electrician) I should be good.
I wonder where you can source all those sweet oven doors and all that cool iron work, need to start looking.
Happy new year by the way. Seems a lot like last year, 'cept I gotta start paying FICA again so it's actually worse than the end of last year. Great.

Good Man..

Thank you for the links. Excellent. Good points all. That Russian stove can be built my anyone that can put two bricks together.
Incredible efficient design. The longer you keep heat trapped inside, the more efficient the stove becomes.
Find an old house in your A.O. that they are demolishing. You can probably get the fire bricks for free. Just the labor of hauling them off.
The more efficient the stove, the less wood you need.
Incredible the man with the barrel stove started the fire with newspaper. No kindling.
The Russian stove makes the heat work too get out. Rather than just shooting up the chimney.
If it gets any colder in sunny Florida. I may be building one. :)

Yeah they basicly are, but that design has been around a lot longer then the rocket stove. They both use the same basic principle, burn some fuel hot and fast, and trap the energy in a heat mass. I think the rocket style ones use less fuel since it has a small feeding area, but I also think they need to be loaded/attended more often, the older design will burn longer because it can hold more fuel and doesn't need as much attention.
There's a video on YouTube of a guy that built a rocket mass heater with just bricks, it reminds me of a compination of a rocket stove & Russian stove but smaller, it looks like it takes up less floor space then a pallet (40"x48") would and maybe about 4'-5' tall.

What I would do is study both designs and combine them together to fit your needs.

Hell this guy designed a low cost down draft rocket style stove out of barrels and never knew it.
The pic (only one) sucks but you get a good idea how it works. The large barrel is the downdraft fire box, the pipe that goes into the small drum goes almost to the top and the chimney pipe is a seperate pipe that goes down into the barrel. This forces the heat to stay in the barrel longer and radiates more of it.
THE ULTIMATE BARREL STOVE





The Russian stove makes the heat work too get out. Rather than just shooting up the chimney.
That's the main downside of most stoves (even new ones) and fireplaces, 60-80% of the energy from the fuel goes up the chimney, make this energy travel a little further and through a battery (bricks or clay) to save as much of that energy as you can. That's why I said earlier about just putting bricks around a basic wood/coal stove will save a lot of that heat as well.

If you have access to a good supply of used motor oil, a waste oil burner makes sense. We have a Clean Burn at the shop, it was pricey to buy but now that it's setup all we pay for is the electricity to run the pumps and fan, plus minor maintenance items like a filter every year. Other than using compressed air and heat to atomize the heavy oil, it is essentially the same as a standard heating oil burner.

For the DIYer, the old MEN waste oil burner has been updated considerably since it was introduced back in the day:

Mother Earth: Waste Oil Heater

And if all ya have is an old woodstove, you can modify it to use dripped in oil, just set it up to drip used motor oil on the burning log. Log lasts longer and acts as a wick for the oil. Just make sure it's an airtight stove!
