How stuff works? Electric Kettle

Theres nothing as simple and comforting as
putting on the kettle and sitting down with a hot
cup of tea. The science behind how it works is
really quite straightforward too.
In part three of our how stuff works series, we
take a look at how electricity powers our kettles.

A Brief History When gas cook-tops became more
widely available around 100 years ago, the
whistling electric kettle, otherwise known as a
steam electric kettle became a popular kitchen
appliance. The premise was simple, water in the
kettle would boil, building pressure which was
forced through the lid, releasing a high pitched
whistle.
By 1922, steam kettles were replaced with
electric kettles, invented by Arthur Leslie.

Russell Hobbs then manufactured their K2 electric
kettle in 1959, which featured a cool-touch
handle and lid, preventing people from burning
their hands3.

If youve ever wondered how kettles work, were
going to break it down for you. Inside each
electric Kettle is a metal coil. Electrical
energy travels through the coil, turning into
heat and warming the cold water inside it.

How it

• The process looks a little something like this
• When the kettle is turned on, a large electric
  current flows through the coil, or the heating
  element.
• The coil has an electrical resistance (a measure
  of the difficulty to pass an electric current
  through it). This resistance turns electrical
  energy into heat as it passes through coil.
• The heat brings the water inside it to boiling
  point.
• Some electric kettles use a thermostat, which
  prompts them to switch off when the water reaches
  the right temperature.

How To Save Energy By Using Electric Kettle More
Efficiently?
Kettles are already 50 more efficient than
stovetops when it comes to boiling water, but you
could save even more energy by avoiding these
three common mistakes

• Your kettle will work harder if youre filling
  it with large amounts of water. Save on energy by
  only using as much water as you need.
• Forgetting to turn off kitchen appliances can
  add up to 5 of your energy bill. Save on standby
  power by switching off after every use.
• Sometimes, your appliances just need a little
  TLC. If you dont clean your kettle often, you
  might see a build up of limescale. Remember to
  clean it at least once a month. This will keep it
  in good order.
