Limescale is a common mineral buildup caused by hard water, which is rich in minerals like calcium and magnesium. If you’ve ever noticed white, chalky deposits on your appliances, such as your kettle or washing machine parts, you’re not alone. However, while limescale might affect the performance of your household appliances, it’s important to know that it has no impact on the quality or safety of your drinking water.
What is Limescale?
Limescale is primarily formed when hard water evaporates or is heated, leaving behind mineral deposits, particularly calcium carbonate. Malta, being a region with a lot of limestone, naturally has harder water that can result in more visible limescale on household appliances.
Limescale on appliances—like kettles, heating elements, or washing machine parts—occurs when water with high mineral content is heated. This does not mean the water is unsafe; in fact, these minerals are often considered beneficial for human health.
Does Limescale Mean Poor Water Quality?
No, it doesn’t. Limescale is not harmful to your health. In fact, Malta’s water is subjected to rigorous treatment processes, such as desalination and blending with groundwater, to ensure it complies with EU safety standards for potable water
Despite the natural mineral content that causes limescale, your drinking water remains safe and of high quality.
Hard Water = Safe Water: The calcium and magnesium in hard water are actually beneficial to your health and are often added to dietary supplements. Many experts agree that hard water can contribute to daily mineral intake.
Global Recognition: Malta’s water systems are highly regarded for their use of advanced desalination technologies, ensuring a reliable and safe water supply
How to Manage Limescale in Your Home
Limescale buildup can affect the efficiency of your appliances, leading to higher energy bills and shorter appliance lifespans. However, it’s simple to manage with a few practical solutions:
- Set your geysers/hot water systems at 50degC: This minimizes limescale buildup
- Use Vinegar or Lemon Juice: These household acids are perfect for dissolving limescale from surfaces like kettles, showerheads, and ta
- Regular Maintenance: Clean your appliances regularly to ensure they continue operating efficiently.
Limescale and Energy Efficiency
A common side effect of limescale buildup is reduced efficiency in appliances that use heated water. For example, limescale can cover heating elements, leading to increased energy use as the appliance works harder to heat water.
However, regular descaling can help restore the efficiency of your appliances and keep them functioning longer.
Conclusion: Clean, Safe Water for Everyone
At Water Services Corporation, we work hard to ensure that every drop of water delivered to homes across Malta meets the highest standards of quality. While limescale may be a visible result of natural minerals in the water, rest assured that it does not compromise the safety or purity of your water supply.
Remember: Limescale is manageable, but your water is safe and high-quality—every time.
