2016 Unique Design Low Price Compact Unpressurized Solar Water Heater
Model:SNCS15
Working principle:
Solar vacuum tube was evacuated into the tank, the coating inside of tube can absorb more than 92% heat energy from sunshine.
The cold water in water tank flows into the tube and become hot, because of different density between cold and hot,
there will be a natural circulation in the tube. Hot water will float back to tank.
The polyurethane heat insulation layer can keep the water warm about 2 days without any sunshine.
Consumer can enjoy comfortable bathe anytime.
Feature:
1. Easy installation;
2. Reliable and efficient ;
3. Corrosion resistant materials;
4. Stable solar conversion during the day;
5. Most efficient and most economic model;
6. Ideal for many solar water heating applications;
7. Economic goods surpass their money with good efficiency;
8. Aluminum frame, Galvanized steel frame, or color steel frame;
9. Simple structure and working principle but the most economical.
