I have a question , what's the best way to determine how clean my stove is burning ? The only tool I have is an IR gun. I built (modified) my stove to accommodate my wood source which is narrow strips just under four foot long. The average thickness is around 3/4x1-1/8", with extremes from paper thin( the bomb for fire starting) to strips that I must rip in half to fit the feed tube. For now my wood source is green with a lot of moisture, but the heater has no problem reaching over 1000 F on top of the heat exchanger. One thing that's come as a big surprise, secondary air doesn't give a temperature increase unless I have the feed tube completely full . So for now I'm not using it. I light a tunnel fire and once the heat exchanger reaches 500+ F, I close my tunnel door and open the feed tube to fill it with wood. Once I close the feed tube , the temps will steadily climb to 900+F . I get around two hours before the heat exchanger drops below 600 F, then I refuel. It's nice that I can leave and come back hours later and simply drop in some thin strips of wood and the stove will fire right off again from the coal bed under the feed tube. I haven't had any issues with back flash when opening feed tube to refuel. I do have creosote in the feed tube, but no issues with that. I have been amazed that I can reduce primary air and still maintain 900F heat exchanger and have 180F Exiting the heat exchanger . I built A really nice transition coming from the heat exchanger to the flue pipe . It's 8" in height and tapers out 18" to receive a 7" pipe. I have 18' of pipe inside the shop to extract as much heat as possible. The stack going through the roof is a 5" double wall pipe. So my pipe starts out 8", then seven, then 6", then 5". Thanks to everyone for all the shared information because that made my stove build so much more successful.
Thank you Matthew, I appreciate the reply back . I have watched your YouTube stove videos many times and got a lot of good info there. My riser is still metal, but I lined it with duraboard. I think I'm ready to try and build a new stove with a refractory riser and burn chamber. It's so cold here in Kentucky, I'm having to run the stove full bore because of condensate in the exhaust stack.
Did you take pictures of your barrel-to-flue transition?
I built the feed tube long enough to hold the wood (as is from the pallet mill) without having to cut it. I get around three thousand pound bundle for seven dollars.The feed tube is roughly the same height as my riser tube. 48" riser and 50" feed tube. I have noticed when I get the feed pipe loaded with a good hardwood like hickory and red oak the temperature on the exchanger will reach over 1000f. But at this point the expanding air slows the draft down to where the feed tube wants to overcome the the riser if I open the lid to the feed tube. It's no problem because I don't refuel until I hear the stove start cooling down as it's running out of fuel. I will try and post some photos, bare with me because I'm a total novice at this.
Smokeout do you use a p-channel? I wonder if this would help the burn at all. You may need to cover it at start up but I believe it would help greatly once you have good draw established. Might take some creative adapting for such a tall feed tube, which is interesting to have.

deadstarsstillburn: Hi there. I was directed this way by folks on the Permies.com website and am hoping I can get some information on how a total newbie can get started designing, siting, building, and not-dying-in-a-horrible-house-fire with a new RMH in a 160-year old home

deadstarsstillburn: The people over there recommended either a 6" batchbox or an 8" J-tube. I don't know what those are but am going to try to figure that out. What I need is a blueprint that I can scale to fit the need for my house. I have something likne 5000 square feet

deadstarsstillburn: but I do not need to heat all of it by any means. probably only need to heat half of that, maybe less.
Oct 21, 2020 6:53:15 GMT -8
deadstarsstillburn: moreover, the house has 3 storeys (large attic) so I assume if I get very efficient heating on the ground floor, that will go a long way toward heating the upstairs as well, no?

dcoyte: I am planning to use a cast iron heat exchanger out of a hydronic boiler set on top of my rocket stove, flue out the top. There will be a pump moving the water through the heat exchanger into an unpressurized 2000 gal tank. Any thoughts?
