100L High pressure solar geyser

100 Litre High Pressure Solar Geyser (100L) — Reliable, efficient hot water

The 100 Litre High pressure solar geyser (also written 100L High pressure solar geyser) is a compact, efficient hot-water solution that cuts electric water-heating costs and keeps your household supplied with hot water even during load shedding. With a Geyserwise Controller for smart temperature management and a professionally issued Certificate of Compliance (CoC), this system is a safe, compliant upgrade for South African homes.

How many people can a 100 Litre High pressure solar geyser support?

A 100 Litre High pressure solar geyser is generally recommended for 1–2 people, depending on shower length and temperature preferences. As a guideline, an average person uses about 50 litres of hot water over a 24-hour period. If your household has longer showers, large baths or multiple back-to-back showers, consider upsizing — otherwise this 100L High pressure solar geyser is a cost-effective starting point.

How a High pressure solar geyser works

A High pressure solar geyser is designed for municipal (on-grid) water supply. In domestic systems, anything above ~200 kPa is considered high pressure, with ~400 kPa a common operating point. This means the hot-water pressure at your taps can match your cold-water pressure (assuming similar pipe sizing), delivering a comfortable shower experience from a 100 Litre High pressure solar geyser.

Solar collectors harvest the sun’s energy and heat water in the storage tank. The Geyserwise Controller lets you monitor temperatures, schedule the element (backup), and protect against overheating or freezing. Many households see a substantial reduction in electricity used for hot water — often around 40% or more, depending on usage patterns and climate.

Collector technology: vacuum tubes vs flat plates

• Vacuum tube collectors excel in cooler and variable conditions and can be more tolerant to angles of sunlight. Tubes are typically easy to replace individually if damaged, and quality tubes are engineered to withstand typical hail conditions.
• Flat-plate collectors are robust, neat on the roof, and perform very well in sunny climates with good orientation, however, flat panels are not as durable as tube systems in colder weather temperatures.

We’ll recommend the best collector type for your roof, orientation, budget and climate so your 100 Litre High pressure solar geyser delivers dependable hot water year-round.
