Flat plat solar energy collecting components——composed of series parallel flat plat solar radiant energy to heat energy.

When the temperature T1 of temperature sensing probe of collector is higher than a set T2temperature of output water of circulation loop, the intelligent control will start the circulation pump automatically. (compulsory circulation)
The circulation pump make working medium cirle in the circulation pump, to pass the heat collected by the collector to the heat storage tank, to increase the water temperature contiously in the tank.
During the working of circulation pump, when the temperature gap is less than a certain point, it will stop working.
 When the water temperature TR in water box reach the set highest tempeature, the controllor will stop the circulatioin pump. The circulation system has function of automatic emission for over pressure and automatic adusting pressure.
The asistant electricity heating system can help to maintain the upper water temperature automatically; ensure hot water supply in cloudy and raindy weathers.
