SOLAR SWIMMING POOL HEATING!

General Info

We believe that solar heaters need to be flexible. Most importantly flexibility means the solar panel can freeze solid full of water. A black heat exchanger with the clear night sky will freeze at 42F not 32F. The solar collector operates below air temperature at night. During the day, if there is no water flow the solar collector will be much hotter than the air. This is heat transfer by radiation either way. So the solar collector needs to be flexible otherwise you have to make sure it is fully empty every night in the late part of the season. That means a typical rigid 4x12 polypropylene solar collector must be sloped to drain (can't use it on a flat roof) and the system pressure must be low enough to allow drainage and water has to be able to pass through a sealed 3 way valve. "Solar valves" allow this drainage through a small built in check valve. We don't like to rely on that and we don't have to because our collector is flexible. We don't like the idea that one mistake and you have to buy new solar collectors. Flexibility is also important in that the solar surface can flex. Rigid polypropylene strap down grid style solar collectors have to move around on the roof as their manifolds expand and contract with temperature. This side to side movement can easily be 2 inches. The entire sheet has to go along for the ride under straps that only allow for 1/2" of movement. (Limit the size of a bank to 5 collectors when using polypropylene 4x12's) With our flexible collectors they just flex. No shuffling around under straps. Flexibility also allows our collectors to be glued directly to tile roofs. No roof penetrations are required and our system is rated for maximum hurricane code resistance without a single roof penetration. Powerstrip is the clear best choice for tile and flat roofs.
