I found a good deal on a 2006 pacific energy 27 insert wood stove. The super 27 has the same size firebox as the PE super, and my question is, how would it perform compared to a new 2016 pacific energy super insert? What technology does the new 2016 pe super insert have that the 2006 super 27 does not. assuming all of the consumables ( baffle, firebricks, glass, gasket) on the super 27 were in good shape, Thank you for your help.
