| U~Pipe |
U-Pipe Evacuated Tube Solar Collectors are smaller and more compact than heat pipe evacuated tube solar collectors. While the two collectors have nearly identical efficiency ratings, the U-Pipe Collectors actually require fewer tubes up on the roof to reach the same peak efficiency levels. The U-Pipe collectors have the same copper tube as a traditional heat pipe collector, but it actually bends around on itself at the bottom of the glass tube and returns directly into the manifold. This enables the water to travel through the tube for direct gain from solar radiation and also eliminates the need for heat exchange which creates a far greater efficiency rating |
