How does electric water kettle work?

It can be quite comforting to watch an electric kettle boil water as you wait to relax and enjoy your me-time with a cup of tea. But have you ever wondered how an electric water kettle works? Well, the science behind is actually quite simple. But before we get to know the working of an electric kettle, let us understand how people boiled water before electric kettles.

History of kettles

Before the advent of electric kettles, people used steam kettles. One had to place the kettles on the gas stove and the water boiled. The building pressure of the steam would push the lid, emitting a whistling sound alerting the user that the water was boiled. All this changed when in 1922 electric kettle was invented. This was further improved upon by adding a cool-touch handle and lid, preventing people from burning their hands.

The process of the electric kettle

1. When an electric kettle is plugged into an electric outlet and switched on – the electricity flows through the concealed heating element which contains metal coil. Electricity passes through the coil, turning into heat and warming water inside it.

2. As an electric kettle is a sealed unit, the temperature rises quickly and pretty soon the water starts to boil.

3. Earlier, electric kettles had a problem – they didn’t have an auto switch-off feature. It was seen as an electrical hazard.

4. Modern electric kettles like Kutchina electric water kettles come with an automatic shut-off feature that stops the appliance once the water is boiled.

Save energy by using electric kettles efficiently 

Electric kettles are more efficient than steam kettles. However, you can save more energy by using it efficiently. Here are some ways to use your electric kettle efficiently:

• Don’t fill it all the way: Electric kettles come with water level indicators. Instead of filling up the entire kettle, only boil as much water as you need.

• Switch off after every use: Like any other electrical appliance, it is recommended that you switch off the electric kettle when it is not in use.

• Clean at least once a month: Cleaning an electric kettle regularly is important to help it function optimally and to prevent scaling.
