Why convert to solar a solar geyser?

Many low-income residents in South Africa, don’t have access to electric geysers and instead using paraffin cookers, coal burners and kettles to heat up water. Using this equipment can be dangerous because it reduces indoor breathing oxygen and it can also escalate into fires. Using electrical kettles is safer but contributes to greenhouse emissions which results in global warming.

Using this equipment can place a financial burden on low-income residents because of the electrical costs or medical costs associated with the use of coal or paraffin to heat water.

A solar geyser is an outstanding alternative for heating water. Using the sun to heat water is much cleaner, safer and sustainable. The sun is the main source of energy, therefore, people are much safer from increasing electrical prices and also fossil fuel sources. Kettles and electrical geysers contribute to a lot of strain on South Africa’s electrical power supply. Solar geysers eliminate these strains.

Many poor areas in South Africa has little to none infrastructure to accommodate electrical geysers and electrical supplies can not always cope with excessive electrical loads. This can lead to costly repairs of electrical distribution systems. Solar geyser installations avoid these strains and limitations for these communities.


Solar geyser types

Solar geysers work on 2 principles. The darker the object the more absorption of heat will occur. When water heats up, it rises up due to density differences between hot and cold water.


Solar geysers are made of 3 main parts:

  • A collector
  • Storage tank
  • Transfer fluid


Solar geyser collector

Capture incoming solar energy as heat which is transferred to the water directly or indirectly.


There are two types of solar geyser collectors:


Solar flat-panel collector

Consists of a dark transparent front cover, collector housing and absorber. Trustworthy track record of reliability and excellent performance.

Solar evacuated-tube collectors

Consists of a solar absorber inside a glass tube with a vacuum between the two tubes, with a heat pipe in the middle containing heat transfer fluid. Solar evacuated tubes offer excellent performance for heating water using solar. Inner glass tube faces outward to absorb the sun’s energy.

High-pressure solar geyser / low-pressure solar geyser

Solar geysers are manufactured to be high-pressure solar systems and low-pressure solar systems depending on the needs of a household. Although high-pressure solar geysers are more expensive than low-pressure solar geysers, they are more reliable to handle water pressure. Low-pressure solar geysers use less expensive materials and need only to be durable to hold the water and not have much resistance to water pressure.



Solar heat transfer

Transfer of heat can be accomplished directly or indirectly. Direct solar geyser collector heats water directly and circulates the water between the solar collector and the storage tank. The water in the solar system is the transfer liquid.

An indirect solar geyser is where the sun heats the transfer fluids which flows around the storage tank. Indirect solar geyser system is perfect for use in any conditions in South Africa. Natural convection can circulate the fluid or a pump can be used for circulation.



Solar geyser installation methods


Split coupled system

The storage tank is located in your home, usually inside of the roof. Installing the tank above the collector for a passive solar geyser system.

An active solar geyser system uses a pump for water circulation.


Close coupled system

Very popular solar geyser installation system and it’s also very efficient. A solar collector is mounted on top of the roof which also consists of a water storage tank mounted on top of the collector.
