I know my house it too big for my Acentra 52 insert but it's a secondary source of heat to my heat pumps here in Maryland. The pumps are efficient until we go below freezing. Below that and they need some help. Enter the Harman. I have a vaulted ceiling with a balcony open on both sides. It's typically 5+ degrees warmer up there than in the room with the stove. I just got a freestanding fan to push the heat back into the family room with the insert. Was wondering if I'd be better off sending the heat away from the stove, over the balcony back to the main floor to circulate better. Now that I've got you totally confused...thanks in advance for any thoughts.
