The GeyserWorx Controller is used in GeyserWorx' hot water systems. The system utilizes a dedicated solar PV array to heat water in your existing geyser during the day. It uses micro-processors to feed the heating element with DC voltage directly. During the day, the solar PV will heat your water to 70 C. AC power will be used during times when the Solar Power is not sufficient to keep your water at all times above 55 C. This will:

        • Ensure you always have hot water;
        • Save on your current electricity bill (between 30% to 50%);
        • Reduce the load on your current solar installation;
        • Give you all the control over your hot water through an App on your phone.


Available models:
- Single Controller for Single Geysers
- Dual Controller for Dual Geysers
