Hi- I'm a newbie and am having a Regency I3100 insert installed next week. We have a 3000 sq ft ranch with a partial basement and I'm hopeing to heat the whole house. It's an open floor plan. Fireplace is in the center of the house in a sunken great room with vaulted ceiling and ceiling fan. I am in the process of insulating the heating ducts as we have a 60ft run through the insulated crawl space to one end of the house. I plan to use the furnace blower to circulate the fireplace heated air. I had a thought that I probably also should insulate the cool air returns since I want to keep that air as warm as possible as it is going to be recirlulated. I saw another post where someone mentioned they put an air return vent high up on the wall in the room with the fireplace to suck the warmer air into the air return and recirculate that. That makes sense as I really want to circulate the warmer air that is higher up, not the cooler air at floor level, which is where most of the cool air returns are located. We also are having blown insulation put in all our attic areas. Just looking for any feedback, ideas, or oppinions! I have been lurking here for a few months before having just registered and feel I have become so knowledgable just from reading the posts here. Eveeryone's ideas have been very helpful. Looking forward to joining the heating with wood family. Thanks for the help!
