Thermostatic Draft Control -- an interesting blast from the past

[EddyKilowatt]

Here's an interesting Mother Earth article from 1982 or thereabouts -- back in the early mists of secondary combustion and catalysts -- about a home-brew pneumatic l draft-control thermostat:

Cleaning Up Wood Heat for 1982-83 (Scroll down to "Part III", although the other stuff is interesting too.)

I found this while Googling the Condar "Stovetemp" thermostat mentioned by Craig in another thread. There really *isn't* very much new under the sun, it seems....

Interesting that it never made it in the marketplace. As you will read in other articles, this control was also the basis for a super-clean burning design...also developed by Condar, which included a catalyst. This design was licensed to some early cat stove makers and turned in good numbers.

But wood burning (all of it) fell out of favor during a 15 year period from 1985 to about 2000. That is why we have not seen as much evolution as we could have....a 1986 Encore is really not much different than a 2006 one, nor is an 1986 Avalon.
