Description

Product Description
The Apollo APSP-15 Solar Geyser Retrofit Kit is a complete solar water heating conversion solution that allows an existing 150L electric geyser to be upgraded into a solar-powered system without replacing the geyser tank. The system works by installing evacuated tube solar collectors on the roof, which preheat water before it enters the existing geyser.

This retrofit system is designed for high pressure domestic installations and is suitable for standard municipal water supply systems. It uses solar energy as the primary heat source during daylight hours, significantly reducing electricity consumption while retaining the existing geyser as a storage tank.

The system typically operates using a circulation system that may be pump assisted or thermosiphon based, depending on installation configuration. A differential controller and sensors regulate water movement between the solar collector and geyser tank to ensure efficient heating performance.

This kit is widely used as a cost effective alternative to full solar geyser replacements, making it ideal for homeowners looking to improve energy efficiency while reusing their existing geyser infrastructure.
