Thanks for those links Xringer. Last year I had gathered about 10 sections of downpipe in aluminum 10' long and 2 5/8 square for free from work with the intention of building one of these. After seeing what's possible I'm all fired up again to complete the project.
I'm not sure I'll use the same fan setup they did, I might be able to scrounge something closer to Daox's attic heating system for cheap. We'll see as I study. It's really cool that they're mounting these horizontally in a low position where they don't stick out as much. I just have to consider knee high snow.
The first vid immediately helped me determine what size I need to heat my house and the second vid helped me visualize the house connection and the plenum better than I had before, so thanks again!
