An ETC Solar Water Heater uses evacuated glass tubes to absorb solar radiation and heat water efficiently. It is the most popular type of solar water heater in residential and commercial applications, especially in areas with cold or moderate climates.

1. Sunlight enters the evacuated glass tubes.

2. The inner coating absorbs heat and transfers it to the water inside the tubes.

3. Heated water rises naturally into the storage tank (thermosiphon principle).

4. Cold water flows down into the tubes to be heated again.

5. This cycle continues, keeping hot water available in the tank.

A Solar Water Heater System (SWH) is a device that uses sunlight to heat water for residential, commercial, and industrial applications. It is one of the most cost-effective and widely used solar technologies, helping reduce electricity consumption significantly.

These systems typically heat water up to 60°C–80°C, making them suitable for daily use such as bathing, cleaning, and industrial processes
