Why is water quality critical in hot water systems?

Water quality is critical in hot water systems primarily because it impacts the efficiency and lifespan of components. When water contains impurities, such as minerals, sediment, and other contaminants, it can lead to several operational issues. For instance, hard water with high mineral content can cause limescale buildup in pipes, heat exchangers, and water heaters. This buildup reduces the efficiency of heat transfer, making the system work harder to achieve the desired water temperature, ultimately leading to increased energy costs.

Moreover, the presence of corrosive agents in the water can accelerate corrosion in metal components, leading to premature failure of fixtures, pipes, and appliances. This not only shortens the lifespan of those components but can also result in costly repairs and replacements. Overall, maintaining high water quality ensures that hot water systems operate efficiently and have a prolonged service life.
