OK, here goes. I've been lurking here for a while and have gotten some great info. My insert (Lopi Declaration) is being installed in about a week, and I've been noodling on the best way to circulate the warm air. The unit will be in my family room, adjacent to the kitchen with a six foot opening in between. I figure it'll be pretty easy to keep those two rooms toasty. Beyond that anything else will take some effort. I have a central AC system, separate from my heating system with the heat exchanger in the attic. Intake ducts are upstairs (top of the stairs and a couple of bedrooms). Would it make sense to open up one of the intakes and the outlets downstairs in the family room by the stove, and run the fan periodically, bringing cooler air to be warmed, and pulling some warm air up the stairs? I know I'll lose *some* heat circulating through the cold space, and running the fan isn't free, but the system is meant to circulate air throughout the house. Seems to me that it should work. Any thoughts? Thanks!
