River Club is a high-value residential pocket of Sandton, typically with multiple geysers or a heat pump on buffer storage, and in many cases pool or underfloor heating on the same plantroom. Gauteng municipal water is moderately hard, so scale on elements and heat exchangers is the single most common cause of falling performance.
