How long does it take a kettle to boil?

The time it takes to boil water depends on the amount of water and the power of your heating device:

Electric Kettles:

• 1500W: About 4 minutes for 1 liter (4 cups).
• 2500W: Around 2-3 minutes for 1 liter (4 cups).

Microwaves:

• 1500W: 4-6 minutes for 1 liter (4 cups).
• 700-800W: 10-12 minutes for 1 liter (4 cups).

Stoves:

• Gas: 6-8 minutes for 1 liter.
• Electric: 8-12 minutes for 1 liter.
• Induction: 5-6 minutes for 1 liter.

In general, higher power means faster boiling. Electric kettles are usually the quickest as they are most efficient, followed by microwaves, with stoves taking the longest.
