Have any of you guys had any creosote build up from pellets? I was just reading a blurb about pellets and the guy said that he had a creosote build up. I have never found any creosote in my stove or exhaust

Five years of straight pellets no creosote ever.

I think someone is confusing soot for creosote. I don't think I could get my stove to burn low enough to make creosote. These stoves burn hotter than a normal wood stove. You get some different resins from pellets and corn but it's not flammable that I've ever seen.
Probably some guy from the DNR, the same one that told me 20 years ago that black bears don't climb trees. And that was two hours after a big sow had me stuck in my tree stand for over an hour at dark sniffing my boots.

Here is just one of the places that talks about creosote. The other places I found are from owners who have had creosote (or what they are calling creosote)actually build up in their stove.

Indeck makes a good product, but that reads like an infomercial. No name as to where the research comes from. Anyone that has burned wood for heat knows that softwoods are a problem in regular stoves/furnaces without proper cleaning and burning. I just can't see a low enough temp in these pellet burners to not burn up the VOC's before they can accumulate and cause problems.
I guess if you don't have the stove set properly it could happen, but not as hot as mine burns.

command_z might be referring to me. I tried to burn some pellets on my lowest setting and my heat exchange tubes developed this shiny sheen to it after running for 12 hours. I admit, maybe it wasn't creosote, but I'm not sure what it was. After I altered the air setting to increase the amount going to the burn pot then ash or soot started accumulating and then I eventually brushed down the tubes on my next cleaning, so I don't know what it was. From what I can tell based on a dictionary, soot = fine powder with mostly carbon which makes it black, creosote = flammable tar substance from volatile gasses condensing. From what I can tell on my Google searches, chimney people, or at least chimney cleaners expanded "creosote" to three stages.

1) fine powder (what we probably call soot and technically could be flammable since it has carbon in it unless it's got a high ash/non burnable material content)
2) porous gummy/flaky (can still probably get it off with pipe brushes)
3) shiny tar substance that has to be scraped off

The interesting thing is, on wood (I guess it's the same for pellets since it's still wood) the gasses are given off when it burns at 500F and gasses burn up at 1100F. While I have no clue if it gets that high inside these stoves, it does say that if the flue gas drops below 250F (seems to be 150F-250F) then it's POSSIBLE for any unburnt gasses to condense and deposit on the pipes.

lol, no drysun, I was referring to some discussions at www.hearth.com. Most people there say that yes pellet stoves can generate creosote but only if not burning correctly. I think that is possible.
