Commonly referred to as gas water heaters, gas geysers operate without water storage tanks and heat the water directly as it passes through the appliance. Their pricing typically falls in the range of R4000 to R9900.
Gas geysers function independently of electricity, eliminating the need for an electrical connection. With their high energy-efficiency, gas geysers are among the best options available, offering capacities from as small as 5 litres to as large as 20 litres.
Understanding Gas Geysers
Unlike electric geysers that store and heat water in a tank, gas geysers are tankless and heat water on-demand. They offer significant energy savings as they only heat the water when it’s needed, eliminating the need to maintain a large tank of hot water.

Types of Gas Geysers
Gas geysers use Liquid Petroleum Gas (LPG), typically stored in cylinders, outside your home.
Choosing the Right Size
The right size of your gas geyser is determined by your household’s hot water needs. A professional plumber, like our experts at Fox Plumbing in Benoni, can help calculate your demand. They consider the number of hot water outlets (showers, taps), the number of residents, and simultaneous usage needs to recommend an appropriately sized unit.
Energy Efficiency
Gas geysers are inherently more energy-efficient than traditional electric geysers, but efficiency can vary between models. Check the energy rating of potential geysers; a higher rating indicates a more energy-efficient model. Remember, an energy-efficient geyser may cost more upfront but will save more money over its lifespan.
Safety Features
Safety is paramount when dealing with gas appliances. Ensure your chosen geyser has essential safety features, such as an oxygen depletion sensor, flame failure device, and overheat protection. An accredited installer will ensure safe and correct installation as per local regulations.
Brand Reputation and Warranty
Consider the reputation of the brand you’re choosing. A reputable brand often ensures a high-quality product with reliable customer support. A warranty is equally important. It gives you peace of mind knowing that if anything goes wrong, the company has got you covered.
Professional Installation
A gas geyser installation involves gas fitting and plumbing work, which should only be conducted by a certified professional. At Fox Plumbing, we offer expert installation services, ensuring your gas geyser is installed safely and efficiently, complying with all local codes and standards.
