[TheForge] OT - wood stove catalytic combustors, heat extractors, etc. (was: Barrel Stove Kits)

[Bruce Freeman]

I just looked up "Magic Heat" and it's described as a heat exchanger
only (with thermostated fan).  OTOH, there are Condar's catalytic
combustors which actually burn the gases, but wear out after 10000
hours or so, they say.  And I don't know whether they can be installed
in a flue pipe, or whether some special stove is needed for them.

Does anyone out there use these things?  What luck have you had?  How
do they install?  How often must they be replaced?  Do they reduce the
need for chimney cleaning (with brush)?

I probably will not be using my wood stove all that much anyway, so my
inclination is to do without.  From two test burns I find the smoke
quits when the thing heats up anyway.
