Description

Product Description
The Apollo APSP-10 150L Solar Geyser Retrofit Kit is a solar water heating conversion system that allows an existing 150L electric geyser to be upgraded into a solar-powered system without replacing the tank. The retrofit design uses solar collectors installed on the roof, which preheat or fully heat water before it enters the existing geyser tank.

The system typically uses evacuated tube or flat plate collectors combined with a circulation system that transfers heat into the existing geyser. Depending on the configuration, it may use a pump and controller or thermosiphon-assisted circulation to move water between the solar collector and the storage tank.

This retrofit solution significantly reduces electricity consumption by using solar energy as the primary heat source during daylight hours. It is ideal for households looking to improve energy efficiency without the cost of replacing an entire geyser system. The kit includes essential components for solar integration and is suitable for standard 150L domestic geysers.

Retrofit systems are widely used in South Africa as a cost-effective alternative to full solar geyser replacements, offering energy savings while retaining the existing plumbing and tank infrastructure.
