Handy little accessory for Wood stoves

There aren't very many Weatherized homes with wood burners as the main heat source (there were only 77 weatherized between April 1, 2010 and March 31, 2011).  But for those few houses that do, this looks to be a low cost means of distributing some of that heat away from the stove. 

Any Weatherization providers participating in the Northern Indiana Wood Stove Changeout Program, it might be worth looking into.
