Using the Power of the African Sun

There is a false rumour about Solar Water Heating not working, this is because through the recent trend of solar water heating in South Africa, there was a lot of people who jumped on board to try make a quick buck. This resulted in a lot of people installing solar geysers without the knowledge of how the system works or how to install them. We live in amazing weather conditions for solar water heating and its crazy that we don’t make enough use out of the sun. A solar water heater installed right, will save you loads of money.

Types of Solar Geysers

There are 4 types of Solar Water Heating Systems. These systems come in low pressure or high pressure. Low pressure systems rely on gravity feed and are not ideal for big homesteads, but more for security guard houses and low cost housing. High pressure systems come in indirect or direct.

The difference between indirect and direct: Direct solar geysers, the sun heats the collector/ manifold and this heat gets transferred directly back into the geyser. Indirect solar geysers, the sun heats the collector/ manifold and this heats a coil that runs inside of the geyser, which heats the water in the geyser. The reason for this is so that one can put Glycol (anti freeze) into the system to prevent the pipes circulation the suns heats from freezing. This is suited for areas that are prone to pipes freezing.

Thermosyphon System

(Direct and Indirect available)

  • The geyser and the collector are both on the roof.
  • This does not require sophisticated timers and pumps.
  • It works the most sufficient out of all the solar geysers available and requires the least amount of maintenance.
  • Cold water sinks and hot water rises.
  • So as the cold water sinks to the solar collector it comes out the other side higher than the cold water inlet and creates a circulation motion, pulling the cold water into the collector and pushing the heated water into the geyser.

Split Pump Solar System

(Direct and Indirect available)

  • The geyser is inside the roof and the collector is outside on top of the roof.
  • Because cold water sinks and hot water rises, there is no way for the heated water in the collector to transfer back to the geyser with out the use of a pump.
  • Often people just fit a pump without a intelligent timer. This is bad, because the pump will circulate the water continuously and not give the collector time to heat sufficiently.
  • It is important to have a good intelligent timer that sends signal to the pump and collector, ensuring that the maximum heat transfer takes place.

Low Pressure Solar System

(Only Thermosiphan)

  • Low pressure solar geysers are only good for low cost housing or guard houses.
  • The heating also works thermosiphan, however the tubes are attached to the geyser and the water inside the tubes and not a collector.
  • The water to the geyser first feeds through the small filler tank on top of the geyser. Once the geyser is full, a float valve in the filler tank shuts off, similar to a toilet cistern.
