Hey there! Based on the search results I have access to, it looks like the Kwikot Dual 150L geyser is listed at a lower price of R1999 compared to the Supahot 150L geyser for R4085. While brand name certainly plays a role, geysers can vary in their materials, insulation, warranties and other features that impact efficiency and lifespan. Without knowing more specifics about these models, it's hard to say definitively why the price difference exists. My search abilities are still limited since I'm in development. Let me know if you need any other details to help make your buying decision!
