Our furnace's aren't the most efficient units. But I do want to get every BTU I can out of my heat discharge openings. And the 4 inch heat ducts that we have. I don't like the internal air turbulence that the outside wall creates. All the cracks in the walls. Plus the lack of any insulation. So I went off to Menards to come up with what is hoped will be more efficient. First is improving airflow. I have one run to the back that is 13 ft long. I had very little airflow. Then with all the heat lost along the way to the rear. i got some 4 inch rigid aluminum dryer duct. Then some 4 inch 90 degree elbows. This will get the smooth air flow I want. But the heat lost is a problem. Next thought is to cover the outside with the reflective bubble wrap. Held on with contact adhesive. Any other ideas out there? Bob Dunahugh78 Royale
