Evacuated Tube Collector (ETC) Systems

Evacuated Tube Collector (ETC) Systems – Description

Evacuated Tube Collector (ETC) Solar Water Heating Systems are engineered for maximum heat absorption, high efficiency, and quick water heating, making them one of the most effective solar thermal technologies available. Designed for both residential and commercial hot water needs, ETC systems deliver reliable performance throughout the year with minimal maintenance.

🌞 How ETC Systems Work

ETC systems consist of multiple evacuated glass tubes that capture and retain solar heat. The vacuum inside each tube minimizes heat loss, ensuring faster heating even during:

• Low sunlight
• Cloudy weather
• Early mornings or late afternoons
