Do Electric Kettles Use A Lot of Electricity? Answered 

Do electric kettles use a lot of electricity? Before buying the right one for home use, here is everything you need to know.

Do electric kettles use a lot of electricity?
Many electric kettles range from 1200 watts to 1500 watts or even 2000 watts

Electric kettles are some of the most valuable innovations for the entire human race. Long gone is the time when you need to fill up water into a large cooking pot and flame it over a gas stove.

Many electric kettles range from 1200 watts to 1500 watts or even 2000 watts. So the only real question here is how to choose the proper kettle that doesn't eat up much energy needlessly.

How Many Wattages Does An Electric Kettle Produce?

The answer to this question lies in the exact model you have at home. But on average, most electric kettles for home use produce from 1500 like this COSORI Electric Kettle with 1.7 liters in capacity.

That means it will consume 1.5kWh per hour daily. However, you barely use up to an hour daily to boil water. I put the boiled water into my thermos flask to keep it hot for hours. 

COSORI Electric Kettle with Stainless Steel Filter and Inner Lid, 1500W Wide Opening 1.7L Glass Tea Kettle & Hot Water Boiler, LED Indicator Auto Shut-Off & Boil-Dry Protection, BPA Free, Matte Black
  • THE PUREST WATER FOR YOU--Your kettle is made with superior-quality 304 stainless steel and borosilicate glass to keep your water safe and tasting pure for years to come
  • COMPLETELY SAFE--No need to watch your kettle while it’s boiling. It automatically shuts off 30 seconds after it finishes boiling, and boil-dry protection prevents the kettle from turning on when there is no water
  • WIDER OPENING--Your electric kettle is designed with a wide-open mouth for quick cleanup of any residue or limescale using lemon juice or baking soda
  • NO MORE WAITING--A great choice to replace your microwave, stove or your old kettle; British STRIX Tech ensures you can enjoy quick boiling times ranging from 3—7 minutes so you can enjoy your coffee, tea, or oatmeal in no time
  • CONVENIENT & DETAILED--Specially design the non-drip V-shaped spout and scald-proof lid for easily controlling the flow and preventing scald

If you need it to make tea or coffee, the average time I see is usually five minutes. You might drink five cups of coffee and tea every day, but you still spend less than 1.5 kWh daily. And this specific amount is applied for one full kettle of 1.7 liters of water. If you boil less water than that, you will need less time to boil and less energy at the end of the day.

If you only use a kettle to make tea and coffee daily, I have another smaller electric kettle that uses less energy. This Fellow Stagg EKG Electric Gooseneck Kettle is designed to pour-over coffee and teapot. It only holds 0.9 liters and only eats up 1200 watts.

Which Is More Cost And time-effective: Electric Kettles Or Cooktop Stoves?

A gas stove is not the best energy-saving resort to heat water since the energy is wasted

So to wrap this up, should you go for an electric kettle or a cooktop stove to boil water? Well, my money would go on the kettle. Electric kettles are the better choice given such a great convenience and a short amount of time to get the water ready. 

A gas stove is not the best energy-saving resort to heat water since the energy is wasted.

One thing you should know about how electric kettles work is the metal coil placed under them. This metal coil will be heated when you turn on the kettle, and a large electric current flows through the coil to begin cooking. Therefore, the energy wastage is minimized to save you more time, energy, and money.

What To Know Before Buying An Electric Kettle

What to know before buying an electric kettle?

It seems to be a no-brainer when buying such a simple gadget as an electric kettle. But you don't want your money to go to waste at the end of the day, do you? Here are some essential tips from my personal experience so you can go home with the best buy.

  • Make sure the kettle boils water effectively.
  • Secondly, how noisy is it? Have it tested before adding it to your cart. If you cannot try it in a store or buy it online, read the reviews to see if anyone complains about the noise. 
  • The best electric kettles for home use will go fine with 1.7 liters for your daily purpose. Of course, you can go for a bigger one if you have a big family or if you need to store it in a thermos flask for later use or prepare multiple drinks for your customers at a café.
