Over time, what is a common issue in hot water systems if maintenance is neglected?

In hot water systems, neglecting maintenance can lead to increased sediment build-up over time, which is a common issue. Sediment, often made up of minerals like calcium and magnesium, can accumulate at the bottom of water heaters, particularly in areas with hard water. This accumulation can decrease the efficiency of the heating element, requiring more energy to heat the water and leading to higher utility bills.

As sediment builds up, it can also cause other problems such as reduced heating efficiency and potential damage to the tank itself. The presence of sediment can lead to fluctuations in water temperature and may create uneven heating, resulting in discomfort for users. In severe cases, it can even cause the tank to overheat, leading to the risk of tank failure or bursting. Therefore, regular maintenance, including flushing the tank to remove sediment, is essential to ensure the proper functioning and longevity of hot water systems.
