FAQ Solar Water Heating

In South Africa we are lucky enough to have sunshine 9 days out of 10 – making us one of the most energy-rich nations of the world!

Solar geysers offer a huge step forward for households and businesses in South Africa that are looking to cut down on their energy bills. Not only that, but using solar energy will help the environment as the world seeks to move rapidly away from using fossil fuels.


01. How does a solar thermal system work?

A: A solar thermal system consists of a number of components; a solar collector, a pump, a controller and a hot water storage tank.

The solar collector, located on the roof, collects the sun’s energy and transfers the heat to the storage tank. The storage tank allows the hot water to be stored until it is used at night or in the morning.


02. What is the life expectancy of a solar system?

A: The life expectancy of a solar system is more than 20 years (closer to 30 years).


03. What is the average pay back of a solar thermal system?

A: Solar hot water systems can save a homeowner or business a substantial amount of money. At current energy prices, these systems can pay for themselves in about 2-5 years, depending on the application.


04. How long will it take to install a solar system?

A: On average it takes less than a day to install a solar system.


05. How much maintenance and service is required?

A: Our solar technology requires virtually no maintenance of the system except for wiping clean the collector surface if it collected dust. We do however recommend that the system be checked annually to ensure that you are getting the best possible efficiency out of the system.


06. What happens if on an evacuated tube collector a tube is broken?

A: On our evacuated tube heat pipe solar collectors the system will remain operational, only the efficiency of the system will be reduced slightly. Replacing the broken glass tube is a very simple and inexpensive operation.


07. Will a solar hot water heating system work on a cloudy day?

A: Yes. Although the heat output of the solar collector is reduced on overcast days it will still be able to provide heating. Approximately 25-30% of the sun’s energy actually gets through the clouds.


08. Can I use a solar hot water heating system with my existing hot water system?

A: Yes. ITS manufactures a special conversion valve to change your normal geyser into a solar geyser.
