A lot of old Earth Stoves are pretty good and not dragons. I had a 10 scallop Earth stove here for 3 years before I replaced it with an Englander NC-30. damm if the Earth Dragon did not smoke any more or burn any more wood than the English stove. It did produce more creosote though. I put the Earth Stove up for $200 on Craigslist here and it was gone within 2 hours. They are well respected in these parts, where they were originally designed and made.
Yep many good older stoves out there, my Nashua is a heat monster with dry wood and like you I am not sure how much wood I am saving.
Yep just a little joking around. I have two wood stoves in my house. The one up stairs is a epa stove and works great. The one down stairs was a less expensive vogelzane epa stove that did not draft worth a crap. So I decided to modify it and more or less converted it into a smoke dragon. It works great now and drafts good. I have been out side with both of these stoves going and I never see any smoke coming from the down stairs and it burns just as clean as my upstairs stove. So like you guys say it is the dry wood you burn and how you burn that makes the most difference.
Let's bring something to light here on that name "Smoke Dragon" also, Even in the owners manual of some of the early stoves, they claimed they were "trash burners" and would/could burn anything! A lot of dealers were selling them on the point as you could even burn your house trash. Hence, "smoke dragon". If you go back into the late 70's and find some old advertisements, it's right in them. Also, older coal/wood stove's were a major culprit as well, us as wood burners with "experience" now know, whats right, clean and wrong! There are others who still think, "just throw it in, it'll burn" and that attitude is what gives us wood burners an bad name.
