Improved Solar Water Heater for Domestic and Industrial Usage



Until today several models of solar water heaters (SWHs) are introduced to the market. The oldest and 1st generation of SWH in date before 1900, involving a black-painted tank mounted on a roof. The 2nd generation is flat-plate collectors used for the first time in the 1920s. The 3rd generation of SWH is evacuated tube solar collectors in few different forms of U-shape pipe, thermosiphon and heat pipe.
In 4th generation design, the system is without hot water tank storage and produce hot water instantly. 

  • 20% cheaper system (in terms of system components maintenance)
  • Compact design causes to less infrastructures on the buildings
  • Reliable structure make the system easy to use
  • Flexible structure for domestic and industrial

Potential Market:

  • Small/medium size domestic applications in tropical regions & Single season Countries
  • Combination of compact and conventional heat pipe solar collector for Industrial application
  • Potential for Cooling systems (integrating with an absorption chiller

The advantages:

  • Increase the absorbed energy portion
  • Regulate the hot water output to normal range
  • Working all over day and night
  • Less than 1% heat waist.
  • No stratification problem
