Solar Geyser Element

The system makes use of photovoltaic technology and a unique PTC AC/DC element to heat the water in the geyser. This differs from the traditional thermal hot water systems where water is cycled from a collector through pipes to the hot water cylinder by either making use of a 220V pump, 12V pump or thermo siphoning. Solar water geysers rely on warm water rising, better known as convection. This is how water circulates through the panels. The hot water in the tank then moves into the cylinder, usually located inside the house. Meanwhile, the cooler water in the tanks flows downwards into the absorber (collector).

Most geysers have a five-year guarantee. Some models typically having larger or higher-wattage heating elements, as well as thicker insulation. In addition, models with larger heating elements have much better resistance to mineral build-up or scum.
