How does Solar heating system work?

The solar heating system comprises of a hot water storage tank and solar heat collector / panels. The glass-covered collector consists of a flat, black aluminum heat-absorbing plate that is precision-fitted onto a copper manifold wherein the water runs. Through a thermo-siphon effect (in which hot water rises), hot water circulates between the collectors and the tank, while the sun is out, and is stored at the end of the day in an insulated storage tank. All systems are equipped with an electrical heating element as a backup, controlled by a thermostat for those odd days when the sun's energy is insufficient for water heating.

Solar water heating has been used commercially around the world for more than 50 years. In several countries it is mandatory to have a solar water system in every home. Here is why more and more homeowners across Africa are installing solar water heating:

• Free hot water - An average sunny day in Africa generates sufficient solar energy to
  provide all your hot water without using electricity.
• Saving - a solar system is the only appliance in a home that actually saves money
• An Investment - Installing a solar water heating system adds to the value of your
  property and constantly saves you on running costs.
• Environmentally Friendly - Solar energy is clean energy - no pollution and no
  exploitation of limited natural resources.
• Independency - With a solar water heating system you will have hot water even during
  blackouts and erratic power supply.
