Description

Product Description
The Apollo APSP-18 Solar Geyser Retrofit Kit is a high-efficiency solar water heating conversion system designed to transform an existing 150L electric geyser into a solar-powered 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 geyser tank.

This retrofit solution is ideal for households that want to reduce electricity usage while keeping their current geyser installation. It works by circulating water between the solar collector and the geyser using either a pump-assisted system or thermosiphon-assisted flow, depending on installation design.

A differential temperature controller monitors the temperature difference between the collector and geyser tank to ensure efficient heat transfer. This ensures optimal solar energy utilisation throughout the day, significantly reducing reliance on grid electricity.

The APSP-18 kit is widely used in residential applications where cost-effective energy savings are required without replacing existing plumbing infrastructure. It is compatible with standard 150L electric geysers and integrates seamlessly into domestic hot water systems.
