This document was prepared by Thermo Dynamics Ltd. in 2007. Thermo Dynamics designs, manufactures and installs solar pool heating systems. They describe two types of solar pool heating systems — open loop and closed loop — and the flat plate collectors that are used in the system. Typically, open loop systems are for seasonal outdoor pools, while closed loop systems are used for year-round indoor pool heating. The closed loop system requires the installation of a heat exchanger and additional circulators. It also discusses the advantages of each system, transfer fluids used and the type of quality you get from solar thermal pool heating systems.
