OPERATION PRINCIPLE

This system is designed to have the solar collectors on the roof and the storage cylinder installed at ground or floor
level. Electric and gas boosted models are available. The system comprises a hot water storage cylinder, solar
collectors, pump, controller and temperature sensors. The solar control unit ensures water circulates between the
solar collectors and the storage cylinder to transfer heat from the solar collectors to the water in the cylinder if
enough heat is available from the sun.
Supplementary heating is provided if insufficient heat is available from the sun (such as during cloudy or rainy
weather or during winter months) either via an electric heating element(s) located inside the storage cylinder or via
an in-line Gas booster located external to the storage cylinder. The following diagrams illustrate the Split Solar Hot
Water System set up with both Electric and Gas boosting.
