The electricity consumption of an electric kettle it is quite modest.
Still, if you have an old kettle and you are considering to buy a new one, it may worth to check the electricity usage of both the old kettle and any kettle that you are interested on.
TABLE OF CONTENTS – QUICK NAVIGATION
Depending on the model, kettles use between 2000 and 3000 Watts of power, being 3000 Watts the most common wattage for kettles.
As an example, our kettle is rated as 3000 Watts (W) so this means that for every hour of use to boil water it will consume 3 Kilowatts (kW).
3000 W / 1000 = 3 kWh
We are using our kettle for maybe half an hour every day so the kettle is consuming 1,5 Kilowatt hours (kWh) of electricity per day.
3 kWh x 0,5 hours = 1,5 kWh
Because we are paying to our electricity provider 0,217 euro per every Kilowatt hour (kWh) that we consume, using our kettle it does cost us around 32 cents every day.
1,5 kWh x 0,217 euro per kWh = 0,32 euro per day
If you only know the voltage and current of your kettle, you can calculate the power consumption, in Watts, using the calculator below.
For more information about Power, Voltage and Current, scroll down to the ‘Electricity Measurement Units’ section.
The calculator below can be used to estimate the electricity cost of a kettle based on the daily usage.
As you can see, running a 3000 Watts for half an hour a day and 320 days per year, it is going to cost us around 104 euro per year on electricity.
If instead we had a 2000 Watts kettle, with the same usage it would cost us around 70 euro per year on electricity.
But, take in consideration that we lower the wattage (W), the longest it does take to boil the water. A 3000 Watts (W) kettle does boil the water faster than a 2000 Watts (W) kettle.
With this we want to make you aware that saving electricity and money is good but if you are thinking on buying an efficient kettle, be aware of the prize. You don’t want to pay much more for a fancy kettle for just saving 3 euro a year in electricity.
If we had to buy a new kettle and we had to chose between:
> Kettle A: Very energy efficient, it does only consume 28 cent per day on electricity, but it does cost 25 euro more than kettle B.
> Kettle B: Same energy efficient as our old kettle, it does consume 32 cents per day on electricity, but it does cost 25 euro less than kettle A.
We would chose kettle B because the additional 25 euro would have a very long payback period if we are only saving 4 cents per day.
If you don’t know how much you are paying per kWh, you should be able to find the cost per kWh on your electricity contract or in one of the electricity bills.
Alternatively, if don’t have access to your contract or your electricity bills, this website does show the electricity cost per country.
A few other examples from our ‘Electricity usage and electricity cost calculators‘ page that may be of your interest:
If you want to know the exact electricity usage of an air conditioner, your best option is to use a plug in power meter to measure the exact power consumption and electricity cost.
Clicking on the image below it will redirect you to the Amazon page where you can have a look to the specifications of the power meter we use for our measurements.
All of our house appliances and devices like the washing machine, the dishwasher, the TV or the printer are plugged to a wall socket.
So, with a power consumption meter we can determine how much electricity our appliances or devices are using and, more importantly, we can measure the electricity usage over a period of time.
Have a look to this YouTube video for more information.
If you think that your kettle it is using too much electricity, here there are two simple ways to reduce the power consumption of a kettle:
1.- Clean up the limescale accumulation
If you have hard water at home and you use that water to fill up your kettle, over time the limestone will accumulate on the heating elements.
Eventually, that limestone accumulation will make your kettle less efficient and prone to use more eletricity.
If you would like to find out if you have hard water at home, have a look to this informative YouTube video.
2.- Buy an energy efficient model
If you have an old kettle, it may be worth to start considering to buy a newer and more efficient model.
But be careful, do not spend too much money on a mega efficient kettle because it may be not worth. In case of doubt, have a look to this post where we explain how to calculate the payback period.
Depending what it is considered a lot of electricity.
The calculator from the ‘Electricity cost calculator’ will show you the electricity cost based on the wattage of your electric kettle, how often do you use it and how much you pay per kWh.
Between 2200 and 3000 Watts.
Most of the electric kettles use 3000 Watts.
You can use a commercial descaler or you can create your own solution.
Mix one part of white vinegar and two parts of water and pour it in the kettle. Switch the kettle on but make sure that you switch it off before the it gets to the boiling point. Repeat if necessary and once you are happy with the results rinse the kettle with fresh water several times.
Not everybody it is familiar with terms like Watts, Kilowatts or Kilowatt hours so if you would like to learn more about them, have a look to this YouTube video that we have prepared for you.
Or you can have a look to this electricity measurement units calculators to get a better understanding of:

Energy conservation can be defined as the decision and the act of using less energy
Energy conservation both benefit you and the environment
The act of saving and conserving electricity does benefit you because you will be paying less on your energy bills.
And it also does benefit the environment because conserving electricity prevents any unnecessary waste of natural resources.
Now, at individual level it may not look worth to try to save a few watts here or there.
Still, every little counts and if hundreds or thousands of us do save a little every time, it will make an important contribution towards conserving our natural resources.
If we could reduce our kettles electricity usage, even a very small amount, it would make a big impact on preserving our natural resources.
For example, if 9000 households would manage to save as little as 10 Watts per day (0,01 kWh) on the kettles electricity usage, that would add to 32850 Kilowatt hour (kWh) saved per year.
9000 households x 0,01 kWh per day x 365 days per year
32,850 kWh saved per year
That is a considerable amount of electricity, but let’s add additional perspectives for clarity:
> Assuming an average cost of 0,18 euro (or dollars, or pounds, or any other currency) per kWh, we would collectively be saving nearly 6000 euro per year.
> To produce 32,850 kWh of electricity it is necessary to use around 17 metric tons of coal or 56 barrels of residual fuel oil.
In any case it is clear that small energy savings do really count when looking into the bigger picture.
