How does a solar heating system work?
The SunTank solar heating system comprises of a hot water geyser and solar heat collector panels. The glass-covered collector consists of a flat, black aluminium heat-absorbing plate that is precision-fitted onto a copper manifold. In an Indirect system an antifreeze fluid circulates in the manifold due to the thermo-siphon effect (in which hot liquid rises) the hot fluid circulates between the collectors and around the geyser transferring heat to the water in the geyser. In a Direct System water circulates in the manifold and gets stored directly in the geyser. At the end of the day when the sun goes down the hot water are stored in the insulated geyser.
