Advantages of Solar Water Heaters


  1. Solar energy is an abundant and accessible source of renewable energy that can significantly reduce our dependence on non-renewable energies (fossil fuels). Starting to utilize this energy source will be very effective step towards protecting the environment, saving energy resources, and solving national economic concerns. Given the geographic location of Iran, vast areas of the country receive high levels of solar radiation and, with the ever-increasing costs of fossil fuels and electricity, it is time to, like many other countries, tap into the unlimited, clean, and free renewable energy sources such as solar energy.

  2. Some of the best practices to optimize energy consumption and prevent excessive use of fossil fuels and other energies include using solar water heaters, solar cooling, hybrid solar/gas-turbine packages, solar stills and solar generators.

  3. Solar water heaters are among the most effective plans for public and easy use of solar energy to supply hot water for domestic and industrial use, such that the surface temperature of the solar collector absorber can rise up to about 100 °C and, in high-efficiency models, the temperature of the heated water can reach the boiling point.

  4. This energy supply process is so effective and efficient that the very first technology of solar water heaters has been developed in a country like Germany as one of the countries in the northern part of Europe and the pioneer in producing this technology.

  5. Main components of thermosyphon solar water heaters are:

    • Flat panel solar collector
    • Vacuum-insulated hot water storage
    • Clamping base and connections for enclosed expansion chamber

  6. Flat panel solar collectors absorb the solar energy through their absorbent panels made of the most optimal absorbent aluminum sheets and insulating materials. This radiation energy is then converted into thermal energy and then transferred to water or the working fluid as part of the storage process.

  7. A backup mechanism is always used in solar water heaters to supply the thermal energy required for low radiation circumstances (cloudy, rainy or snowy days). The backup system in our products is a wall-mounted tankless gas water heater. This hybrid solar water heater reduces the annual energy consumption of the gas water heater at least by 60 to 70%. This means that, in addition to significant energy savings, the lifetime of the tankless heater is substantially increased due to its lower operating time. It should be noted that the amount of energy saving per square meter of solar collectors is equivalent to one liter of oil per day for 365 days a year. Therefore, in addition to a significant reduction in household energy consumption per year, non-renewable energy reserves are also protected to the interest of preserving the environment.

  8. Solar water heaters are quiet and safe. Other advantages of these systems include easy installation and simple use, especially with regard to the intensity of the sun's radiation in the geographic location of Iran.

  9. Another valuable project in terms of thermodynamic cycle is to provide cooling from solar energy by flat collectors and absorption chiller cycles at a cooling capacity of 5 to 10 tons, which is very suitable for hot and dry and even hot and humid climates. In this method, the cooling energy is generated through an absorption cooling cycle which is operated by the thermal energy (from the solar cycle). In addition to taking advantage of the solar energy, this process gives rise to significant environmental and economic transformations.

  10. Currently, the technical knowhow of producing every single component of solar cooling, and how to set up and operate them, especially with regard to the angle of the sun's radiation, is available in Iran.

  11. Using solar stills is also very simple and effective for regions with very hard tap water, which has the technical and economic justification.

  12. From an application perspective, solar energy is ranked first among the alternative energy resources due to its abundance and ease of access, allowing it to be indefinitely used in various applications.

  13. In addition, solar power generation using photovoltaic cells as well as solar power plants are one of the other applications of this clean energy.
