What a nice long run

I found this yesterday looking up wood stove for sale on Facebook market place.

Well thats an interesting way to get more heat out of your stove.

I think that's at a creosote manufacturing facility.

Here's one from the Center Baptist Church in Thorndike . . . they have one service a year in the Fall so the stove is not used that often.

those fans backed right up to the sheet metal are about as effective as tits on a boar

Keep an eye on that guy, he is going to be selling a new wood stove every year ("...and THIS BRAND sucks too, just like the last ten!")


Also... there's not enough resolution to zoom in much, but...



Is that duct tape around the top?

You dont get creosote if you are burning hot and clean. I expect when that church install is used that poor stove is running flat out on hopefully dry wood.

That's an old Bangor made stove isn't it? I bet it puts out some heat ran wide open.

Back in the day (1800's) those long runs of pipe is what heated a lot of public buildings. They would be taken apart nearly daily to clean out and reassembled. Probably had one person dedicated to this task. Kevin

This install was posted several years back. At least it had enough pitch to stay fairly clean according to the poster.

LOL. Based on the drips coming out of the pipe I think this is correct.

Maybe the tape is an attempt to stop the dripping.

Around here there is an open air museum - 100acres with a small town and farmsteads replicating the mid 1800s. I look at their stove setups and wonder how they survived. Long pipeing runs like those pictured, suspended by stove wire, small hearth pads, leaky box stoves. A few larger buildings have the stove in the center, chimney off to the side with 10 to 30ft horizontal runs. Most smaller houses and buildings had tiny tin sheet hearth pads with wood floors beneath and all around. But they seem to have done alright.

The problem with looking at historical installations is that you only see the lucky ones that didnt burn to the ground.

The family farmhouse here had an old cookstove in the kitchen. Redoing the kitchen floor several years ago meant patching and replacing the burned out floor boards where the stove once stood. It's use would have dated to the 30s and before. Most of the rural homes around are still standing - but it's a wonder how with the stories of chimney fires. About a third of the barns here are gone from fires.

Only if you can keep the exhaust above the condensation point till it exits the chimney.

You are mixing up two phenomena, if the wood is fully combusted be it an old style boiler like mine, a gasifier or a catalyst or a woodstove cranked wide open , you can subcool the exhaust and still not get creosote. You will get condensed water vapor which will run down the stack and possibly rust it out but in order to get creosote you need to start with combustible condensable vapors leaving the stove. The reason these vapors are leaving the stove are they are incombustible like water or they did not burn completely in the stove.

The old UMaine design (Jetstream, Madawaska ) put out water vapor up the stack and that was about it. It could be subcooled but its lot easier to exhaust vapor due to icing. The Europeans use condensing heat exchangers on larger biomass boilers made out of stainless steel before exhausting out a stainless stack.

I do like the efficiency of European designs, but not necessarily the aesthetic of the modern stuff. The US doesn't have the same culture of efficiency.

Yes if you really had complete combustion you would be correct. Unfortunately that is not possible.

Nobody remembers the failures [emoji3061]

Oh wow, that's almost identical to my house, but I left my stove in the center(ish) of the wall to keep any bends out of the stack (plus it's a little more in the center of the room for even heating)... they must have really wanted it in the corner.
