New member here, what a great site! Here's our situation: Existing house is an old 2 storey farmhouse 25'x30' footprint (1500 sq. ft. total). We're adding a large sunroom addition on the back 18'x30' with a cathedral ceiling. The stove we decided on is the PE Averlea T5. I'd like to install a grille at the top of the ceiling where it meets the original house and run a large insulated duct (maybe 10 or 12") through the attic and open up over the staircase. My theory is the heated air from the stove will rise to the ceiling, run through the duct, down the stairs, through the house and return back to the stove. Forming a huge convection loop, heating the entire house. I'm figuring this arrangement will drive itself, but would an inline fan/blower in the ductwork be helpful? Also, the house is well insulated but at 2000 sq. ft. total, should I buy the T6 instead?
