What can excessive sediment buildup in a hot water cylinder lead to?

Excessive sediment buildup in a hot water cylinder can significantly impact the performance and longevity of the system. When sediment accumulates, it acts as an insulating barrier between the water and the heat source. This insulation effect reduces the overall efficiency of heat transfer, meaning that more energy is required to heat the water, leading to increased energy costs.

Additionally, if sediment is allowed to accumulate unchecked, it can eventually cause overheating of the heating element or heat exchanger, particularly if the sediment layer becomes thick. This can lead to the risk of system failure or even damage to the hot water cylinder itself, potentially resulting in leaks or bursts. Regular maintenance and flushing of the hot water cylinder can help prevent these issues, ensuring continued efficiency and safety in operation.
