Description

Product Description
The Apollo APSP-20 Solar Geyser Retrofit Kit is designed to convert an existing 200L electric geyser into a solar-powered hot water system without replacing the geyser itself. The system installs evacuated tube solar collectors on the roof, which capture solar energy and preheat water before it enters the existing storage tank.

This retrofit system is intended for high-pressure domestic installations and is suitable for standard municipal water supply systems. It significantly reduces electricity consumption by using solar energy as the primary heating source during daylight hours, while the existing geyser element provides backup heating when required.

The system operates using either a pump-assisted circulation system with a differential controller or a thermosiphon-assisted design depending on installation requirements. Temperature sensors monitor the collector and tank temperatures to ensure efficient and controlled heat transfer.

This kit is commonly used in residential and small commercial applications where upgrading existing infrastructure is preferred over full system replacement. It provides a cost-effective and energy-efficient solution for households with higher hot water demand.
