Technical Specifications

How It Works – Thermosiphon Heating Explained

1. Absorption: Sunlight hits the vacuum tubes and heats the water inside.

2. Natural Circulation: As the water heats up, it rises into the tank while cooler water flows into the tubes to be heated.

3. Delivery: Gravity feeds the heated water to your taps—no pump or electricity needed!

This simple system is highly efficient and requires minimal maintenance—perfect for Kenyan homes with unreliable power.
