Technical Specifications

How the System Works

1. Heat Collection: The vacuum tubes absorb solar energy throughout the day, rapidly heating the water inside them.

2. Hot Water Circulation: As water heats, it naturally rises to the top of the insulated tank while cooler water descends for reheating—using the thermosiphon principle.

3. Gravity Flow Delivery: When a hot tap is opened, gravity pushes the heated water down to your outlets. No pumps, no complexity—just clean, reliable hot water.

Best Use Cases

• Residential homes for families of 3–5 members

• Hostels, guest houses, or rental flats
