Active and direct solar water heating system

Product Overview

Our Direct Active Solar Water Heating System provides efficient and reliable hot water for homes, commercial, and industrial use. High-efficiency flat plate collectors and a stainless steel storage tank ensure maximum solar heat absorption and consistent performance.

A circulation pump with automatic temperature control optimizes heat transfer, delivering hot water even during high demand. As a direct system, the same water heats in the collectors and supplies your taps, ensuring high efficiency and low heat loss.

Built with corrosion-resistant materials and supplied with a backup electric heater and safety components, the system supports flat and pitched roof installation and delivers long-term solar energy savings.
