Here are a few top options I found for you based on the PriceCheck search results: The Totai 13 GWH10L gas geyser for R4399 is a great affordable option for a household of 1-3 people. As a 10L battery ignition gas geyser, it will provide plenty of hot water for daily use in a compact size. For a family of 4 or more, I'd recommend the Totai 16L constant temperature gas geyser for R7499. Having a constant temperature function means you'll always get hot water, no matter when during the day you need it. The larger 16L capacity also means less re-heating. Some customers prefer solar water heating for its maintenance-free operation and lower running costs. The 10 tube 100L solar geyser for R3150 is then a good environmentally-friendly choice. Just be aware you'll need excellent sunlight for best results. Please let me know if you need any other details on these models or have a different budget in mind. I'm here to help you find the right geyser.
