FAQs: Best Glass Kettle
What are the benefits of a glass kettle?
Glass kettles not only look nice but are also BPA-free. They allow you to see the water level and boiling process, and unlike plastic or metal kettles, they don't affect the flavours of the water.
How to clean a glass kettle?
You can clean a glass kettle with a mixture of water and white vinegar. Fill the kettle with this solution, let it sit for 15-20 minutes, and then boil. After it cools down, rinse thoroughly. For stubborn stains, a non-abrasive sponge can be used.
Are glass kettles durable?
Yes, glass kettles are typically made from borosilicate glass, which is durable and resistant to thermal shock. However, like any glass product, they can break if dropped or handled roughly.
Are quiet kettles worth it?
If you're sensitive to noise or live in an open-plan space, a quiet kettle can be a great choice. They use special technology to reduce the amount of noise produced during boiling.
Do glass kettles consume more energy?
No, glass kettles do not consume more energy than their stainless steel or plastic counterparts. The energy consumption of a kettle depends more on its wattage and efficiency than the material it's made from.
How does a kettle with a built-in filter work?
A kettle with a built-in filter purifies the water as it boils, removing limescale and other impurities. This is especially useful for those living in hard water areas.
What is limescale?
Limescale is a hard and chalky deposit that is mostly made up of calcium carbonate (CaCO3). It’s found mainly where hot water runs - in kettles, pipework and showers. Limescale is more common in hard water areas and over time, it can cause some real damage if it's not removed. Descaling solutions and water-softening treatments can help.
How often should I clean my glass kettle?
The frequency of cleaning your glass kettle depends on the hardness of your water. If you live in a hard water area, it's recommended to clean your kettle every few weeks to prevent limescale buildup. You can read our informative guide to hard and soft water to work out your water type.
