Description

Product Description
The Apollo ASLP-30 300L Integrated Low Pressure Solar Geyser is a high-capacity solar water heating solution designed for households with higher hot water demand. It integrates the storage tank and evacuated tube solar collector into a single roof-mounted system, reducing installation complexity while improving energy efficiency.

The system operates using thermosiphon circulation, where heated water naturally rises from the evacuated tube collector into the storage tank without the need for pumps. This ensures reliable, silent, and low-maintenance operation. The evacuated tube technology allows effective heat absorption even in low sunlight conditions, making it suitable for year-round performance.

With a large 300L insulated storage tank, the system is ideal for families or properties with multiple bathrooms or higher daily hot water usage. Its corrosion-resistant construction and thick insulation help maintain water temperature for extended periods, reducing reliance on electrical backup heating.
