outdoor wood boiler for heating

Post by drifter » Sat Oct 30, 2010 8:16 pm

Has anyone used an outdoor wood boiler for heating there house or shop? I have a few questions first what temp did you run the water at? If you use the 1" pex line under ground can you use any other type of clamps to clamp the lines to the fittings Have you ever used a water to water heat exchanger on your hot water tank? Is it worth puting one in?

Please do your homework here because the EPA has an emissions controlling Model Rule out that they are trying to get state's to adopt voluntarily because they haven'y bothered themselves with creating an area source rule. And the far N/E state's have as well as Washington.

All this is going to make it harder to get them tested and approved, plus way harder to site on your lot so again PLEASE do your homework here!!

Just type in something like EPA's OWB Model Rule and it should pop right up..

I would guess the Swedes here should be able to answer that.. fairly common way to heat houses in Sweden, for some strange reason not common at all here over the border... :?

Fwiw, my good Buddy, Doc has one and all I'm going to say is that at idle it smokes a lot and this is why the EPA is down on them.

Doc's is located right at 50 feet from the front of his place in the trees and works great as far as I'm concerned. Use enough hot water and it's small fan kick's in and it doesn't smoke as much..

I asked my big "Mic" Buddy Murph at work recently about loading a big round bail of hay in it and he said that the ash from the straw has to be "shaken off" the bail or it will choke the burn and the fire will go out...

Do your homework on them. Don't buy according to price. I bought a Central Boiler. In my opinion it is one of the best built. I live in Michigan where we have some pretty good winters and have never been able to keep our house as warm as we do now. Mine barely smokes when its not calling for heat. The biggest mistake people make is they skimp on the underground pipe. Bite the bullet and buy the good stuff.

Look hard at this.

I am NOT going farther bcause what I just typed and deleted is work related and it may get me in trouble. Sorry, but if I posted it, then maybe people could see just how much of a problem SMOKE production is legal-wise nowadays.

PS., but I will post MO rule numbers 10 CSR 10-5.040 and 10 CSR 10-6.220 if anybody wants to dig deeper here.

Look back to the '40's when St. Louis had a Danora, PA SMOG episode and you will see why 5.040 was created to rid the area of hand-fired coal stoves/furnaces!! Rule is obsolete now because we need to burn BIOMASS but need OWB's to burn clean AND NOT SMOKE!!

I am in my second year of using one. All I can say is..if you dont mind cutting wood, its the best investment I've ever made. We heat
our hot water with it, and the improvement in the dishwasher, and the clean clothes are amazing, not to mention the awesome baths
and showers. Mine is a Clear Flame, installed it myself. I am in Indiana, and last year we had a fairly cold winter. I used about 15 truck-
loads of wood last year. Our house is 2600sf, and pretty well insulated.
The smoke is not a big deal, unless you live in town, or have neighbors that are tree-huggers, lol, you can barely see wisps of light
smoke coming out till it requests more heat, then it puts out a fair amount for about 1-2 minutes. I set my upper temp on 180, and it
works out well. Oh- I don't use dry seasoned wood most of the time, because it burns up too fast. Just cut the wood up, stack it, then
only split it when u need to use it, and only split it small enough to load!
Once again--we LOVE ours, and only wish I'd gotten one 10 years ago! I spent ZERO on propane last year--not an exaggeration, and,
I'm not affiliated with any manufacturer. Just try to deal with someone local, that you trust! And...I never cut standng timber, theres
plenty on the ground that works great.

At least the EPA hasn't tightened fireplace regs yet..

My mom had one, I can't remember the brand, and it cost them a ton to have installed. Once operational, it cost them about a log or two a day. You still have to clean out the ash though....

I was thinking about this driving to work this morning on how to cut the smoke production of OWB's.

I'd make one such that the firebox would be made out of a heavy SS cylinder just flapper closed off at the back and hung from the roof just down the middle up top front and rear so it is suspended at two points and can expand and contract. Don't weld the end steel, but rather allow it to float like the cylinderical firebox will do.

Next, leave a 1" or so air gap between the water tank. This will allow the firebox to burn a lot hotter and radiate heat to the water tank because the boiler won't be directly cooling/chilling the shell of the firebox. Burning it a lot hotter wil cut smoke production drastically.

I do know that gigantic power plant water-wall tube boilers are suspended way up top at their four corners such that the whole boiler is suspended loose so it can move in all directions to keep it from cracking at temperature!! It take's a hell of a super-structure to support a gigantic power plant boiler for sure!

The EPA Weirdos are trying to run around and enforce this ANTI-smoke producing EPA law crap in Alaska. It's not going very well for the Obama Voter weirdos. There are a ton of folks up here running these outdoor wood boilers, I been looking at one for my home.

My mother lived next door to a family that used one of these to heat their home. It had a very low chimney,and it smoked like a MF'er. If the weather was just right,it would fill her yard and her house full of smoke. One night the wind shifted and filled the neighbor across the street's house full of smoke and the local fire department responded like it was a full-blown structure fire. (Yes,it was summertime and all their windows were open. The OWB has to burn all the time if you want to use it for your domestic hot water.)

If you live in the middle of nowhere with with sufficient distance between your neighbors,I have heard that they work really good. If you live close to other people,you will become the scourge of the neighborhood. The EPA folks are NOT weirdos. They are our representatives in the government,and they represent people that don't want their houses filled with other people's wood smoke all year round with the same fairness as they represent people who want to use their outdoor wood boilers.

I started building a new garage/shop last fall and had to move the 1000gal propane tank. The guy guy that came to do the digging was telling me he had just installed a coal furnace at his house....yes coal. He seemed to love it, fill the hopper about once a week and the auto controller adjust the coal feed rate to maintain temp. He said coal is really cheap (I'm in rural PA) compared to anything else. Before speaking with him it never occurred to me they even still make coal furnaces.....both my grandparents had OLD homes and both had long LONG unused coal cribs and that was 40+ years ago but it turns out they still make them and google says you can oven get 1 at homedepot. Who knew? Might be a good alternative to wood? It was 200 years ago so it might still be :)

This upcoming winter will be my 3rd year burning coal after switching from propane/electric. Love it. Would never go back. Top the hopper every other day. Empty ash pan every other day. Cut my heating bill in half. Controlled by thermostat 72 degrees all winter long.

EPA should be only for big crap company's, or nonexistent. Liberty means individuals being exempt from that crap, not just boeing jets.
Besides if you where like the kilchers and on your homestead they would have no jurisdiction period.
And outdoor boiler would be the best and safest option for prevention of a house or shop fire. Its best not to have any kind of heating flame that is not personally in constant observation used for heating. So great idea you have.
