Description

Product Description
The Apollo ASLP-20 200L Integrated Low Pressure Solar Geyser is a complete solar water heating solution designed for larger households requiring increased hot water storage. It combines the storage tank and evacuated tube collector into a single integrated system, making installation simpler while ensuring efficient solar energy utilisation.

The system operates on the thermosiphon principle, allowing natural circulation of water between the collector and tank without the need for pumps or electrical circulation devices. This improves reliability and reduces maintenance requirements. The evacuated tube technology ensures high heat absorption even in colder or cloudy conditions, making it suitable for year-round use.

Built with corrosion-resistant materials and thick insulation, the system retains heat efficiently and provides consistent hot water supply throughout the day. It is ideal for low-pressure water systems commonly found in residential and rural installations, offering a cost-effective and energy-saving alternative to electric geysers.
