Solar Hot Water Heating System

 

Structure

Solar Hot Water Heating System consists of solar collectors, project storage tank, pipelines, controlling system, pumps and other accessories.

 

Working Principle:
1) Firstly, the storage tank shall be filled with cold water, the collector loop shall be pumped with water

2) The water in collector loop then will be heated with solar radiation to vacuum tubes

3) When temperature discrepancy sensed between solar collector and storage tank reaches set value in controller, the controller shall start the circulation pump automatically
4) The circulation pump makes water circulate in the loop
5) Hot water would be pumped into storage tank and the loop again be pumped with cold water from the bottom of storage tank
6) In case the temperature in storage tank does not reach set value you want, then the auxiliary electrical heater would start to assist heating
7) When temperature discrepancy sensed between solar collector and storage tank is below the set value in controller, the circulation pump shall stop automatically

8) If the water temperature has not reached the expected value set in the controller, then the auxiliary heating device would start to assist solar water heating

9) Eventually the water will get heated enough as expected ready for use
