How It Works (Explained Simply)

1. Solar Collection: The vacuum tubes collect sunlight, converting it into heat.

2. Water Heating: Cold water in the tank flows through these tubes, absorbing heat as it passes.

3. Thermosiphon Principle: Hot water naturally rises to the top of the tank, while cooler water descends to be reheated.

4. Hot Water Delivery: When you open your tap (at a lower level), gravity pulls the hot water down, allowing flow without pressure.

5. Heat Retention: The insulated tank retains heat for up to 48–72 hours.
