Principles and Characteristics:

●The secondary heat exchanger solar water heating systems, solar collector system operation under pressure, using anti-freezing working fluid in the collector system to avoid fouling in summer and freeze blocking in winter.

●This system uses a single tank setup, tank non-pressure, generally used for timing heating water occasions.

●Automatically water-injecting, collectors automatic temperature cycle, automatic heating and heating water piping loop, manual water-injecting, manual heating, manual pipe loop, manual collector loop.

●Auxiliary heating method depends on user's requirements and the actual situation, the general auxiliary heat source are electricity, gas, fuel and so on.
