This hard water is formed when rainwater filters through rocks like chalk and limescale, picking up hard minerals along the way. Areas which have hard water then boil this in their kettle, where it can then cause issues with both the kettle itself and the taste of water.
You can check if your area has hard water through our postcode tool. Limescale can float in the water as users attempt to dislodge the chalky residue, leaving damage to the kettle and bits in any water boiled. Buying a filtered kettle can prevent limescale from entering any drinks but will not stop build up. To stop this hard water build-up in kettles, you need to get to the root of the problem and learn how to prevent limescale.
Here are a few tips:. Preventing limescale and descaling your kettle are two entirely separate activities. If you wish to descale your kettle once it has limescale, you can do so by cleaning it. When it comes to preventing limescale before it arises, there are both short and long term methods available to tackle this. The short term method of maintenance is partly effective, and the long term method of a water softener entirely effective.
To prevent limescale from building up in your kettle, it requires regular maintenance. We use kettles daily as they can boil water FAST and efficiently compared to other known methods. It is not uncommon to see limescale In your kettle. Water with a high dissolved mineral content, such as calcium bicarbonate and magnesium bicarbonate, is known as hard water. Hard water is high in both mineral content and other dissolved solids. Hard water is rich in minerals and so has an average pH of around 8.
Boiled hard water has an average neutral pH of 7. It is reported that people who live in hard water areas are known to have a reduced chance of heart attacks.
Some areas have a naturally soft water supply which means the water has a very low or no mineral content. Naturally soft water is rich in hydrogen and has an average pH of around 6.
Natural soft water supply usually originates from surface water which comes from lakes, oceans and rivers with igneous rock formations such as granite which are insoluble. Naturally soft water has both low mineral content and low total dissolved solids content which can make the water aggressive and corrosive. Naturally occurring minerals such as calcium bicarbonate and magnesium bicarbonate ions get into the water as it comes into contact with soluble sedimentary rocks containing calcium such as limestone, sandstone and chalk.
Limestone is a carbonate sedimentary rock that is often composed of the skeletal fragments of marine organisms such as coral, foraminifera, and molluscs. Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate CaCO 3.
Sandstone is a sedimentary rock composed of sand-size grains of mineral, rock, or organic material. However, the coral or shell is not only composed of the calcium carbonate, but to contain other minerals. You have to be careful since some of the shell or coral does not have good affinity with your clay teapot. Follow Twitter, 2. Click "Like" on Facebook, and 3. Subscribe in newsletter.

Media Release. The scale built the inside of kettle is essential for tea [ The scale inside the kettle is built-up as a result of the chemical reaction Water usually contains Calcium hydrogen carbonate. Those are the questions this graphic aims to answer. To be able to discuss how limescale is formed, we first need to discuss the concept of water hardness.
Hard water is water which contains a large concentration of mineral ions — these are usually calcium and magnesium ions.
Temporary hardness is caused by dissolved calcium and magnesium bicarbonates in the water, and can be removed by boiling. The formation of limescale is largely a consequence of the presence of soluble calcium bicarbonate in water. This compound can decompose when heated to form insoluble calcium carbonate, which makes up the large part of limescale.
This is what removes temporary hardness from water.
