300L Evacuated Tube Solar Geyser Conversion System

The 300L Evacuated Tube Solar Geyser Conversion System is our largest retrofit solar solution, designed for households with high hot-water demand. This system allows you to convert your existing 300L geyser into a full solar geyser without removing or replacing the original tank. The collector is installed outside, while your existing geyser remains indoors — giving you maximum efficiency, minimal installation disruption, and full use of your electric backup element.

Using advanced evacuated tube technology, this evacuated tube solar geyser conversion system captures heat quickly, even during cold or cloudy weather. The copper-lined tubes absorb heat faster than flat-plate systems and offer excellent freeze and hail resistance. Water circulation happens through a reliable 12V solar pump, ensuring consistent heating throughout the day.

This retrofit evacuated tube solar geyser solution is perfect for large families, guesthouses, lodges, and high-usage homes looking to reduce electricity bills immediately without replacing their existing geyser. You still keep your timer, thermostat, and electric element for backup heating, making this system the most practical and cost-effective upgrade for hot-water performance.

With a 5-year system warranty and minimal maintenance requirements, this 300L evacuated tube conversion is built for South African conditions and long-term reliability.

Ideal For How Many People?

A 300L evacuated tube solar geyser conversion is ideal for 6–8 people, depending on usage patterns.
