Once I decided I wanted to capture heat from the sun, I required some way to distribute it in the house. The obvious answer was radiant heat; turning your floor into a giant low-temp radiator. I spent a lot of time learning about the various radiant installation methods, and decided since I had never done such a thing that I could probably come up with a better system. You see, I wanted to design for performance (ie, minimize the time to respond to a heat call). I also wanted to maximize the amount of heat distributed where I wanted it, avoiding temperature gradiants across the floor.

So, I quickly eliminated the high-mass systems, which take hours if not a full day to raise the temp a few degrees. I also eliminated the common "staple-up" systems installed under the subfloor. Clearly, I wanted to get most of the heat upstairs - not in the basement. The track systems available for tube install don't allow for a reverse-loop design that keeps the temperature even across the floor. My solution was to layout a series of 9 reverse-spiral loops of approx 100 feet each and build my own system of heat transfer track. Luckily, it worked!
