Part 3/9:
One of the key challenges with central water heating systems, like the gas-fired Combi boiler, is their inability to handle simultaneous demand from multiple outlets. While these boilers can deliver hot water efficiently, their capacity to serve multiple endpoints simultaneously often leads to fluctuations in water temperature—an issue that can be highly disruptive. With the installation of POU water heaters at sinks, Michael has effectively separated the systems, allowing for a steady temperature in the shower while doing dishes or other activities without interference.
