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 circulation system solar control unit 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 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 a on in-
line Gas booster located external to the storage cylinder. The following diagrams illustrates the Split Solar Hot
Water System set up for both the Electric and Gas boost.
