Details: Solar water pool collectors are unpressurized solar collectors meant to heat the pool water directly. Cold water enters into the manifold from the pool, sinks to the bottom of the tube, and once heated a little bit, will rise back up to the top of the manifold and exit with the water flow. Pool collectors are the most efficient way to heat water because they come in direct contact with the heated surface in the tube and operate at low temperatures which will allow for minimal heat loss through the tubes and manifold, if any at all.
