Description

Product Description
The Apollo APSP-24 Solar Geyser Retrofit Kit is a high-capacity solar water heating conversion system designed to integrate with an existing 200L electric geyser. Instead of replacing the geyser, the system adds evacuated tube solar collectors on the roof to preheat water before it enters the existing storage tank.

This retrofit solution is ideal for households with higher hot water demand. It significantly reduces electricity usage by relying on solar energy during the day while the existing geyser element provides backup heating when required. The system is designed for high pressure domestic plumbing and is suitable for standard municipal water supply systems.

The APSP-24 operates using either a pump-assisted circulation system with a differential temperature controller or a thermosiphon-assisted configuration depending on installation requirements. Temperature sensors continuously monitor collector and tank temperatures to ensure efficient energy transfer.

This kit is commonly used in residential and small commercial applications where upgrading an existing system is preferred over installing a complete solar geyser. It provides a scalable, cost-effective energy-saving solution while retaining the original geyser infrastructure.
