OPERATION PRINCIPLE

Close Coupled systems are designed to have the solar collectors on the roof and the storage cylinder above the
collectors, all mounted using available mounting brackets. Electric and Gas boosted models are available. The
system comprises of a hot water storage cylinder and solar collectors. The Close Coupled Solar System uses
thermo-syphoning principle to circulate the water through the collectors and then to the storage cylinder without the
need for a pump.
Supplementary heating is provided if insufficient heat is available from sun (such as during cloudy or rainy weather
or during winter months) either via an electric heating element located inside the storage cylinder or via a Gas
booster located external to the storage cylinder. The following diagrams illustrates the Close Coupled Solar Hot
Water System set up for both the Electric and Gas boosting.
