1. Solar vacuum tube was evacuated into the tank,
the coating inside of tube can absorb heat energy from sunshine.
2. 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.
3. The polyurethane heat insulation layer can keep the water warm
about 3 days without any sunshine.
Consumer can enjoy comfortable bathe anytime.

1. Imported Stainless Steel.
2. Reliable and efficient.
3. CE Approved.
4. Stable solar conversion during the day.
