The solar water heating system has good economic benefits and is a manageable system project that can be installed or built as a diy solar water heater.
What is a passive solar water heater?
- The passive solar water heaters are simple heating systems that utilize the free solar heat energy without the use of an external energy to transfer the hot and cold solar fluids.
- This is the most popular way of harnessing the free sun energy as they are the least expensive, simple and reliable.
- Such a system uses the principle of physics (heated water rises to the upper part of the tank) to transfer the heat from the solar collector to the storage tank.
- Passive systems can be used for direct domestic water heating or indirectly by circulating the solar heat transfer fluid through the heat exchanger.
Why solar water heaters are developing very well in China?
- The introduction of solar thermal energy heating systems (water heaters), which use solar energy solution directly as heat, is making progress in China,manufacturing and marketing Europe, and other areas.
- Solar water heaters make hot water from solar heat and are used to supply hot water to homes.
- China’s installed capacity (cumulative total) as of the end of 2010 in particular accounted for approximately 70% of the world’s, with a difference of more than ten-times the capacity compared to the second-place Turkey.
