What makes an electric kettle energy efficient?
When you’re looking for an energy-efficient kettle, there are several key features that contribute to reducing energy consumption. Understanding these can help you choose the right electric kettle for your needs.
Double wall insulation: A kettle with double wall insulation has an inner and outer layer with an air gap in between. This design acts like a thermos, helping to keep boiled water hot for longer. By retaining heat, it reduces the need to boil water repeatedly, which is a passive way to save energy.
Variable temperature control: The ability to choose specific water temperatures for different beverages is a significant energy saver. Many teas, such as green tea (around 80°C) and white tea, as well as some coffees (around 90-95°C), don’t need to boil water at 100°C. Variable temperature settings prevent you from wasting energy by boiling more than you need.
Keep-warm function: The keep-warm function allows the kettle to maintain water at a certain temperature, usually for between 20 and 30 minutes, or even up to two hours in some models. This is useful when you want a second cup immediately after the first, as it saves you from having to boil again. Although the keep-warm function itself uses some energy, it uses much less energy than reboiling cold water.
Cup indicators: Many energy-efficient kettles have water level indicators with markings for the number of cups. These encourage you to boil only as much water as you really need, avoiding the common habit of overfilling. Boiling less water uses less energy and takes less time to boil.
Concealed element: Kettles with a heating element hidden beneath a flat metal base are more energy-efficient. This design prevents limescale buildup on the heating element. Because limescale acts as an insulator, it reduces the kettle’s efficiency to heating water and the kettle has to use more energy to reach boiling point.
Automatic shut-off and boil-dry protection: These are important safety features that also help save energy. Automatic shut-off ensures the kettle shuts off immediately after the water has boiled, saving energy spent on unnecessary heating. Boil-dry protection automatically shuts the kettle off if it is accidentally turned on without enough water, also preventing energy waste.
Rapid boil technology: Some kettles have high-powered heating elements that bring water to a boil very quickly. While the power used during rapid boiling may be higher, a shorter boiling time can potentially slightly reduce the overall energy use for each boil, especially when you only need a small amount of water.
Smart features (remote control, scheduling): Modern smart kettles offer you features such as remote control via an app and the ability to schedule boiling times. These allow you to boil water only when you need it, allowing you to manage energy use more effectively in your daily routine. For example, scheduling it to boil just before your morning coffee can prevent it from being on standby for long periods of time.
How to make an electric kettle more energy efficient?
Even with an energy-efficient kettle, how you use it can make a difference in your energy consumption.
- Only Boil What You Need: The simplest way to save energy is to fill the kettle with only the amount of water you’ll use immediately. Avoid filling it to the top if you only need a cup or two.
- Descale Regularly: Limescale buildup on the heating element makes the kettle work harder. Regular descaling helps the element transfer heat efficiently, reducing the energy needed to boil.
- Switch Off at the Wall: Even when turned off, some appliances can still draw a small amount of power. To completely eliminate standby power, switch off your kettle at the wall socket when you’re not using it.
- Use the Right Temperature: If your kettle has variable temperature settings, use a lower setting when appropriate for your drink. Boiling to 100°C for something that only needs a lower temperature wastes energy.
- Use a Flask: If you need hot water to stay hot for a while, pour the boiled water into an insulated flask or thermos instead of leaving it in the kettle on a keep-warm setting for a long time or re-boiling it later.
FAQs
How much energy does my electric kettle use?
An average 3000W electric kettle uses about 0.11 kWh to boil 1 litre of water. Total energy use depends on wattage, capacity, and how often you boil.
Why does my electric kettle use so much energy?
Kettles use energy heating the water and the appliance itself. Boiling more water than needed or heating to 100°C for drinks requiring lower temperatures wastes energy. Limescale also reduces efficiency.
Which electric kettle uses the least energy?
The best electric kettles with features like variable temperature control, cup indicators, dual-wall insulation and efficient heating elements use less energy by preventing over-boiling and retaining heat.
How do energy efficiency ratings work in the context of electric kettles?
Energy efficiency in kettles is often measured by “boil-dry efficiency”, assessing energy used to boil a specific amount of water. Look for energy labels or certifications like Energy Star for guidance.
Do faster electric kettles use more energy?
Not necessarily. While they use more power (wattage) while on, rapid boil kettles heat water faster. This shorter duration can sometimes result in slightly lower overall energy use per boil.
How can I save money when using my electric kettle?
Save money by only boiling the water you need, descaling regularly, and using variable temperature settings if available. Switching off at the wall also helps reduce standby power.
