All, re the recent conversations about heating with wood, I ran across 
this interesting good looking new stove:

This stove is basically a newer version of an older idea from the 
sixties and seventies, called a "Free Flow" .  The tubes were intended 
to extract and distribute a large amount of heat from the firebox.  
Nearly all of the ones that I knew of have self destructed rather 
quickly, as the inner surface of each tube would get very hot, and 
expand, around the much cooler outer surfaces. The welds between each 
tube would be torn apart by disproportionate expanding and non-expanding 
metal.  Any of the Free Flows used in this cold Ontario climate were 
compromised, in less than a decade of service.

Also, as Corwyn has pointed out, the stove did infact extract a lot of 
heat, which caused the fire to cool too quickly, and as a result, the 
second half of the burn, of each loading of the stove, went down hill 
fast, and caused a lot of incomplete combustion, and subsequent creasote 
build up in the chimney.

It is, though, at first glance, a very sexy looking device.  Makes you 
really want to think it will succeed.
