solar vacuum tube feature:

1. Unique three-layer absorption technology
2. Unique Three-Layer(stainless steel/red copper/aluminum), allowing high temperature endurance and preventing peeling off even when the glass gets waxy degeneration
3. Unique Three-layer against degeneration, color feding or performance degeneration due to exposure the empty vacuum tube under the sun over time, extending the life of the product.
4. Incorporating three layer interference coating technology.
5. Unique super pure copper surface, allowing lower reflection and minimal heat loss.
6. Ideal heat collection efficiency in extreme cold water, with hot water available at a temperature of -30C
