Commercial Hot Water System Failure in The Hill
The site loses hot water during peak periods while plant appears to be running. This page covers how we diagnose and repair it on hot water systems in The Hill.

The Hill is a high-value residential pocket of Alberton, 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.
