Water heating is one of the biggest electricity users in a South African home, which makes a solar geyser one of the fastest ways to cut your bill. Here is what you need to know about the main options and the safety components involved.

Thermosiphon Systems

In a thermosiphon (close-coupled) system, the water tank sits above the collector on the roof. Hot water rises naturally into the tank while cooler water sinks to be heated — no pump required. It is simple, reliable and cost-effective, ideal for many homes.

Pumped (Split) Systems

In a pumped or split system, the tank sits inside the roof or at ground level and a small pump circulates water to the collector. This suits homes where a rooftop tank is not practical and gives a neater finish.

Retrofits vs Complete Kits

A retrofit connects a solar collector to your existing geyser, saving cost. A complete kit replaces the geyser with a purpose-built solar system for maximum efficiency. We stock both, plus evacuated-tube and flat-plate collectors.

Safety Valves Matter

Solar geysers get hot, so correct safety components are essential: a temperature-and-pressure (T&P) safety valve, pressure-control valve, vacuum breakers and a tempering valve to deliver safe water temperatures at the tap. Always have installation done to standard by a qualified plumber.

Which Should You Choose?
