As we're all putting increased efforts into living a more sustainable life, energy-efficient alternatives have been popping up for pretty much all our household essentials, from oven alternatives to cheaper heating options. And kettles are no exception either.
Certain features can improve a kettle's energy efficiency. Heat preservation, fast boiling and temperature control settings are great in reducing the power required from a kettle.
A kettle requires between 1200W and 3000W to boil, and all those cups of tea and coffee can add up to have an impact on your energy usage over time. If you're looking to reduce your energy consumption and your carbon footprint, consider replacing your current model with an eco kettle.

FAQs: What is an eco kettle?
Eco kettles are designed to use less power with each boil. They're also produced with the intention of lowering the environmental impact from their materials and manufacturing process.
Certain features can improve a kettle's energy efficiency. Heat preservation, fast boiling and temperature control settings are great in reducing the power required from a kettle, as well as using sustainable materials when constructing them.
Stovetop kettles can be good for the planet, too, as their carbon footprint from manufacturing can be much lower.
What to look for when buying an eco-kettle?
“If you’re in the market for a new kettle, choosing one with a rapid boil function is a great option as it heats the water up much faster than your average kettle. Equally, picking one with a ‘keep warm’ setting will mean you can go back for a brew later without having to boil the kettle again.
Having a kettle that has a high level of limescale build up can be a factor as to why your kettle is using more energy than it should be. This is because the water will take much longer to boil.” - Katy Roberts, AO.com’s kettle expert
Energy efficient kettle features
Insulation
You’ll often find that eco kettles kettles have thicker insulation than regular kettles, and occasionally, you might find that they’re double walled. This added insulation is designed to keep your water hotter for longer, reducing the need to reheat your water and thus saving energy.
Variable Temperature Settings
Energy efficient kettles usually offer variable temperature settings, allowing you to heat water to specific temperatures rather than boiling it to 100°C (212°F) every time. This is useful for different types of beverages that require specific water temperatures - simply put, it stops you from having to boil the kettle fully if you only need hot water for your drink or recipe.
Fast Boiling
Some energy efficient kettles are designed to boil water faster than conventional ones. Therefore, as boiling your water requires less time than usual, you reduce your overall energy consumption and time required to heat the water.
Keep Warm Function
Some eco kettles include a ‘keep warm’ function. This function allows you to keep your water at a desired temperature for a longer period of time, reducing the need to reheat the water if you don't use it immediately.
Material Types
Energy efficient kettles may use materials that are better at retaining heat, such as stainless steel or thermal-resistant glass, to minimise heat loss.
