Working Principle:-
For unpressurized solar water heater
1. This system uses the thermosiphon principle, Solar vacuum tube is pluged into the bottom of water tank;
2. The water is filled inside the solar vacuum tube, Solar vacuum tube transmit solar energy to heat energy;
3. The temperature of water inside solar vacuum tube is rising, As the thermosiphon principle.
