What is the typical lifespan of a hot water cylinder?

The typical lifespan of a hot water cylinder is generally considered to be between 10 to 15 years. This estimate is based on various factors, including the quality of the cylinder, the frequency of maintenance, water quality, and usage patterns. Over time, sediment can build up at the bottom of the tank, potentially leading to corrosion and other issues that can shorten its lifespan.

Hot water cylinders are designed to withstand a significant amount of thermal stress, but as they age, their efficiency can diminish. Regular maintenance, such as flushing the tank to remove sediment and inspecting for any leaks, can help extend the life of the cylinder. However, once a cylinder reaches the 10 to 15-year mark, it’s wise to monitor its performance closely and consider replacement as a proactive measure to avoid potential breakdowns or water damage.
