A kettle may bubble and hum softly. But time and again, other noises such as whistling can also be localized. What it may have to do with it, if your kettle whistles, we have answered below for you.
Design and function of a kettle
Kettles have become more and more popular in recent years. Today, a kettle can be found in almost every household. The heating of the water follows much faster than via a kettle on the stove top. To understand the different sounds, it is important to know the individual components:
- Container (made of plastic or stainless steel)
- Lid (made of the same material)
- Heating coil inside the container
- transformer coil (transformer) in the bottom of the container
- Temperature circuit
Typical sounds of a kettle
Therefore, when using the kettle, you may hear different sounds. A buzzing or whirring sound may emanate from the coil. This can be normal due to the design. If it occurs in older devices only after a longer period of use, it is often an indication of damage to the coil. There may also be a creaking or cracking noise.
This can happen when the material of the container heats up and thermal expansion occurs. In addition, of course, the bubbling of the water that begins to boil, as well as – again, depending on the design – possibly a loud shutdown of the kettle. These are usually all the typical noises that a kettle makes.
An unusual noise – the kettle whistles
However, time and again, users of a kettle also observe that it suddenly starts whistling. Indeed, this can sound like the whistle of a whistle on the kettle, but also fundamentally different. There can be several causes for this. But, first and foremost, the heating coil is calcified.
Why the kettle may begin to whistle or sing
Without delving too deeply into the process now: the limescale causes uneven heating, or the water cools down again too quickly in certain areas. In the resulting water bubbles, the pressure inside is then too low, so that these water bubbles literally implode. This is accompanied by very small “shocks” (really very small, hence in quotation marks).
However, this can be transmitted to the housing or other components of the kettle. Then this begins to “sing”. A similar effect can be seen again and again in cars. The car body can be set into a very fine vibration by defective engine or transmission bearings. The vibration frequency then has a very unpleasant effect on the ears in a certain range. So these noises always occur when certain objects vibrate within a certain frequency.
Usually the kettle is only calcified when it whistles
Therefore, you should now decalcify the kettle. In doing so, we recommend that you decalcify the kettle naturally, i.e. not with decalcifiers from the store, but with natural products. You can find out why and how to use these products by following the link.
