Abstract: A floating solar pool heater consists of a plurality of PVC tubes open at their ends and connected in parallel alignment to the tops of several floats. The tubes are open on their ends so that pool water can flow through them, and the tops of the tubes extend above the water's surface. The tubes heat faster than the water so as to effect a solar heating function. In a modified embodiment, the tubes are serially interconnected and a flexible tube is attachable from one end of the tubing directly to a pool water return outlet. Other embodiments employ the use of transparent tubing with darkened tape on a bottom portion, tubing with downwardly extending ends to facilitate water flow by convection currents, and the use of baffles to retard water flow within the tubing so as to effect a greater heating of the captured water. Additionally, tubing having internal air filled floats is also disclosed.
