How Many Watts Does an Electric Kettle Use?

A kettle is one of the staple home appliances which offers great convenience. You can quickly boil your water, make coffee or tea in just a few minutes. Boiling water in a pan and on a stove takes longer and most people aren’t too patient. Additionally, boiling water with a stove leads to a lot of energy wastage. That is why an electric kettle comes in handy for most homes.

However, although the kettle is fast and convenient, there is a price to pay for that; the high cost of electricity.

In this article, let’s explore the little known facts about your kettle, the power consumption rates, the electric kettle wattage, and how to cut down on electricity bills while using your kettle. Keep reading!

What’s an Electric Kettle?

The main difference between an electric and non-electric kettle is the source of power. With an electric kettle, start by plugging it into an electric outlet. The electric currents heat up the kettle’s heating element, thus warming up the conductor plate of the kettle. The electric energy produces heat that is transferred by conduction throughout the kettle.

Water molecules are loose, thus heat is transferred faster through conduction than in convention processes. This makes boiling water in an electric kettle faster compared to using a regular kettle.

How Many Watts Does an Electric Kettle Use? 

Generally, most electric kettles operate at 1200 watts to 1500 watts. The specific wattage depends on the brand and the model of the kettle. Different kettle models have varying wattages and efficiency. The higher the wattage of a kettle, the higher the energy consumption and the higher the boiling efficiency and speed.

Such factors include the kettle’s wattage, use patterns, and efficiency influence the overall energy consumption of an electric kettle. Understanding the wattage enables you to make the right decision when it comes to purchasing the right kettle depending on your needs.

What’s the Energy Consumption of a Kettle?

As discussed above, there are several factors that influence the energy consumption of a kettle. Some of these factors include the usage frequency, the efficiency, the amount of water, and the wattage. An average kettle wattage ranges from 1,200 to 1,500 watts. Some kettles have a wattage of up to 2000W. 

Here’s the formula for calculating the total energy consumption by your kettle when boiling water.

  • Energy Consumption= Power in Kilowatts x time(hours)

For instance: If a kettle has a power rating of 1200 W, it will take approximately 125 seconds to boil water. Therefore, the average energy consumption is 0.04 kWh.

Checking the wattage, allows you to make informed choices when buying the right kettle for your home.

What Are the Average Costs of Using an Electric Kettle?

It takes approximately 5 to 6 cents to boil water in one sitting. The total costs you incur per month depends on how many times you use the kettle in a day.

Also, the size and the wattage of your kettle will influence the amount you incur in a year. 

How to Minimize the Power Consumption with Your Kettle?

Follow these tips to help you minimize the kettle power usage for a more energy-efficient lifestyle.

1. Carefully Choose the Right Kettle

Consider buying an energy efficient kettle with features such as temperature control and automatic shut-off. Such features help reduce the amount of energy the kettle consumes thus saving you money.

2. Proper Usage

Make optimal use of your kettle to do various tasks. For instance, you can make hot beverages, boil water, sterilize some utensils, among other uses. Maximizing the use of your kettle will help you save energy and minimize the costs in the long-run.

3. Regular Cleaning and Maintenance of Your Kettle

A clean and well maintained appliance such as a kettle will operate efficiently. Lime scale and dirt buildup affects its performance and causes increased energy use. Remember to clean your kettle regularly to reduce the costs.

4. Only Fill Up What You Need

Do not boil water more than is necessary. Boiling water that you don’t need leads to energy wastage. Just fill your kettle with enough water just for the task you intend to minimize the costs.

5. Preheat the Kettle

Preheating the kettle before boiling water is a good way of cutting on costs. If you have unused warm or hot water from a previous task, use it to preheat the kettle. Preheated  kettle boils water faster, thus saving on energy.

6. Use Solar Energy

Solar energy is a great way of cutting down electricity costs and reducing your carbon footprint. You can use solar power to boil water using your electric kettle.

To use solar power for your electric kettle, you must have solar panels for harnessing the sun rays and a power station for storing the solar energy. Here are some of the BLUETTI solar panels and power stations recommendations to help you curb the high electricity costs.
