Solar Geyser & Solar Water Heating Questions & Answers



  • How does Solar Geyser works?

    • Solar Geyser relies on warm water rising, a phenomenon known as natural convection, to circulate water through the flat plate collector and to the tank. Hot water storage tank is located above the absorber evacuated glass tubes. As water in the absorber heats, it becomes lighter and naturally rises into the tank above. Meanwhile, cooler water in the tank flows downwards into the absorber, thus causing circulation throughout the system. Top

  • Can the Solar Geyser heat water to a high enough temperature?

    • Yes, in sunny days Solar Geyser can bring water to boiling point. Top

  • Is Solar Geyser a viable alternative to gas or electricity?

    • Yes, Solar Geyser System is an alternative to gas or electricity boosted geysers in the some areas. Averaged over a year, a correctly sized Solar Geyser System can provide 80% to 100% of a household's hot water needs. The hot water system can easily be automated with the natural gas boosted or electric geyser so hot water is guaranteed regardless of sunlight levels. Top

  • How long will it take to recoup my investment?

    • Solar Geysers are much more affordable than many other solar hot water heaters. For a household of 4, the price of a full system may not be too much more than a new electric geysers. Depending on your location (solar levels) and current hot water usage the annual electricity or gas saving will differ. However in a normal household that spends 40% of its electricity bill on hot water heating, the full cost of the purchase may be recouped as quickly as 3-4 years in reduced bills. You will definitely make considerable savings during the life of the Solar Geyser. Top

  • Can Solar Geyser be use in cold conditions?

    • Yes, Solar Geyser can be used in temperatures as low as -10° C, although performance is reduced in such extreme conditions but Good heat output is still achieved in mild sub-zero conditions as long as there is sunlight. Top

  • Will water be heated on a cloudy day?

    • Yes. Although the heat output of the solar collector is reduced on overcast days it will still be able to provide heating. If it is a heavily clouded day or raining, then more electric boosting may be required to maintain water at the required temperature. This system will be automated with the existing electric geyser, so you don't have to worry about running out of hot water on a rainy day. Top

  • How can I be sure of the quality and performance of your products?

    • The range of Solar Geysers meet the rigorous tests set by the relevant industry standards and are made from the high quality components backed by generous warranties. At the end of the day, the quality and reliability of our products and the service we provide as a customer is best demonstrated by our customers. Top

  • Who will install the Solar Geyser on my roof?

    • The Solar Geyser System should be fitted by an authorized and registered dealer will ensure it is positioned correctly. Top

  • What maintenance of the Solar Geyser is required?

    • Under normal circumstances no maintenance of the system is required. Top

  • Will the Solar Geyser be a fire hazard during hot, dry weather?

    • No. The Solar Geyser's components are all high temperature rated and non-flammable so even during strong sunlight, the system will not catch a light or give off any sparks. The majority of the Solar Geyser's components are stainless steel, aluminium and glass. Top

  • Can Solar Geyser be used for a large scale hot water production?

    • Yes. Solar Geyser can be connected in series or parallel to provide large scale hot water production for a commercial setting such as a school, hotel or office building. There is really no limit to the size of the system. Top

  • Can I heat my swimming pool using a Solar Geyser?

    • Solar Geyser Collectors are high temperature collectors, and are therefore ideal for spas, as the volume of water is small and temperature requirements high. For swimming pools, however, the volume of water is large and the temperature rise required is only several degrees. The cost of heating a pool using evacuated glass tube collectors (for domestic purposes) may be prohibitively high. For large scale swimming pools, however, Solar Geyser collectors may be an extremely viable supplement to electricity. Top

  • Where can I purchase a Solar Geyser System?

    • Solar Geysers are available through our official dealer network. Top

  • How long does it take to install my Solar Geyser?

    • Installation is easy. Because Solar Geyser Systems are lightweight, modular and include comprehensive installation instructions, you can expect an average installation to take 3-8 hours. Top

  • Are Solar Geysers expensive?

    • No. In the long term, a Solar Geyser can save you up to 90% of your household's hotwater electricity expenses and over a 20 year period is considerably cheaper than buying a straight electric or gas geyser due to the much lower running costs of a Solar Geyser system. Top

  • How many users can a Solar Geyser service?

    • There are several types and sizes of Solar Geyser Systems available depending on the number of bathrooms and people living in the home. There are systems to suit every home, Please view a list of Solar Geyser sizes. Top

  • How does using solar help the environment?


    • Using solar and other forms of renewable energy reduces reliance on fossil fuels for energy production, thus directly reducing CO2 emissions. CO2 emissions contribute to global warming, an environmental issue which is now of great concern. The average household can reduce CO2 emissions by as much as 20% by installing a Solar Geyser System.
