Why Do Foreigners Rarely Use Electric Kettles Even Though They Are So Convenient?

Although very convenient, electric kettles - a common household appliance in many Asian countries - are seldom used in some Western nations, such as the United States.

With high power and a fast-heating element, electric kettles can boil water in just a few minutes and can be used for bathing, making tea, preparing milk, coffee, and many other purposes.

Why Aren’t Electric Kettles as Popular Abroad?

Voltage Differences

In the United States, most households use a voltage of 100 - 127V, whereas in the UK and many other countries, the voltage is usually 220 - 240V. This means that electric kettles in the U.S. will not boil water as quickly as those in countries with higher voltage. Consequently, they do not offer the same level of convenience everywhere.

Differences in Dietary Habits

Many Asians have a tradition of drinking tea, while many Westerners tend to prefer coffee. As a result, instead of using an electric kettle to boil water, many foreigners opt to buy coffee makers to suit their needs.

Tips for Using Electric Kettles

1.  Avoid Continuous Boiling

Boiling water continuously for extended periods can overload the kettle’s heating element and increase the risk of fire or explosion. To maintain the appliance’s longevity, allow it to rest between boiling sessions.

2.  Do Not Empty the Water Immediately After Boiling

Even if the kettle’s switch turns off once the water boils, the heating element remains hot and can continue boiling the residual water. Emptying the water immediately may damage the heating element; it is advisable to leave about 15ml of water in the kettle to protect it.

3.  Keep the Lid Closed When Boiling Water

If the lid is left open, the kettle will take longer to boil water and consume more electricity. Moreover, not closing the lid might interfere with the auto shut-off function when the water boils, increasing the risk of damage.

4.  Avoid Underfilling or Overfilling the Kettle

Electric kettles have marked minimum ("Min") and maximum ("Max") water levels. Filling below the minimum prevents the safe auto shut-off mechanism from activating, risking overheating and damage to the heating element. Conversely, overfilling can cause water to spill over when boiling, potentially damaging internal components and posing risks of short circuits, fire, or explosion.

5.  Unplug When Not in Use

Over time, the kettle’s switch might malfunction or be inadvertently pressed by another object, causing it to operate unexpectedly. Unplugging the kettle when it’s not in use helps prevent such mishaps.

6.  Avoid Leaving Water in the Kettle

Leaving water in the kettle can lead to limescale buildup, which may cause rust and damage. It’s best to empty the kettle after each use.

7.  Clean the Electric Kettle Regularly

Over time, limescale can accumulate inside the kettle, reducing its heat exchange efficiency and causing it to boil water more slowly. Additionally, the buildup can damage the temperature sensor relay, preventing proper auto shut-off when the water has not yet boiled. Regular cleaning is essential to ensure optimal performance and longevity.
