Solar water heaters can save on water heating costs by reducing the amount of gas and electricity needed to heat water. By using sunlight to heat water instead of combustible sources or fossil fuel-produced electricity, fewer pollutants are being introduced into the environment. Solar energy is not affected by shortages of electricity and does not stop providing hot water during load shedding.
What are the life-cycle expectation of the system and the total energy savings on it?
Each brand of solar water heaters are different. Solahart solar water heaters have a life span of up to 20+ years, although we have a number of systems that are over 30 years old and are still functioning and providing our customers with hot water free from the sun.
What happens in winter or on rainy days, when there isn’t enough sunlight to heat the water?
Solar water tanks are better insulated than electrical geysers and can keep water hot for a longer period of time. This ensures that there is always a tank full of hot water (and a backup of hot water) in the early evenings/mornings – provided the tank size is correct.
Why is it important that a solar system be tested by SABS?
The specifications on solar water heaters focus on three main areas: quality, performance and safety. Testing systems verify these requirements. As the payback periods are very important it is vital that the solar water heater is of a quality that ensures system longevity.The mechanical performance tests e.g. hail, freezing and pulsation test (testing of the valves) are conducted to ensure that the minimum quality standards are met. The performance tests are conducted to determine how well the system works. The safety test determines if all the safety requirements are met, including electrical and mechanical safety criteria.
Why is it important that solar systems get the SABS mark approval?
The SABS mark of approval takes the test report and adds an evaluation of the manufacturer’s ability to consistently produce quality solar water heating systems. This means that if the testing indicated a high quality, durable and safe solar water heater design, and the manufacturing quality audit indicated that the manufacturing facility can manufacture high quality products consistently, the SABS will allow the manufacturer to use the SABS mark.
How much can it save in your typical electricity bill?
A Solahart solar water heater can help you save up to 80-90% on hot water energy consumption, depending on the system chosen. This translates to a 40 to 50% saving on your total electricity bill.

Jim’s Blog:The National Treasury is hoping to introduce carbon tax on January 1, 2015 in South Africa .
The benefits of carbon tax are monumental when you take into account how companies will be penalized. Carbon Tax will ensure that companies, mines and industry become more responsible in the way in which they run, if they do not they will suffer the consequences and have to pay. It is believed that the introduction of carbon tax will create greener, cleaner, more sustainable and energy efficient ways of running companies. Read more here.
