What is an energy-efficient kettle?

An energy-efficient kettle runs with the lowest energy use possible, using a range of features including powerful elements, low minimum fills and automatic shut-off to reduce their overall electricity use. 

How much energy do kettles use?

How much energy kettles use will depend upon several factors including its capacity, wattage and how much water you’re attempting to boil. 

According to Heatable, on average, kettles use around 0.11 kWh to heat 1 litre of water, costing around 3p every time you make yourself a brew.

What to look for when buying an eco kettle 

If you’re looking for an eco-friendly and energy-efficient kettle, here are some of the main features to look out for:

• Rapid boil zones - How fast does the kettle boil? Most brands will share how long it takes to boil one cup in their specifications - the quicker it can boil, the better, as the shorter running time means you’ll use less electricity as a result. 

• Boil dry protection - Boil dry protection will stop you from turning the kettle on when it's empty, so you won’t waste energy (and time) unnecessarily. 

• Automatic shut-off feature - This will turn the kettle off automatically when the water reaches temperature, cutting the power and stopping further energy consumption. 

• Low minimum fill - To be energy efficient, the kettle should have a low minimum fill level, allowing you to easily make a drink for one without boiling more water than needed. 

• Clear water gauges - A clear water level indicator can allow you to visually see how much water remains in the kettle and prevent overfilling. 

• Concealed elements - Some kettles have elements at the bottom, while others are concealed, meaning they don’t make contact with the water. The latter is preferable, especially in hard water areas, reducing the impact of limescale build-up that can impact efficiency and performance.

• Variable temperature - If you tend to drink more tea than coffee, your kettle could be boiling water hotter than it needs to be. A variable temperature kettle can heat water to lower temperatures, using less energy and allowing you to enjoy your drinks right away.

• Keep warm function - If you’re likely to have more than one cup, a keep warm function can be really useful, maintaining the temperature of the water for a defined time so you don’t need to fully reboil.

How to save energy when using your kettle

• Don’t overfill - Only boil the amount of water you need - especially if making a drink for one. Overfilling the kettle simply wastes energy, takes longer to boil and will cost you more as a result. 

• Maintain your kettle - Cleaning or changing the limescale filter and descaling your kettle regularly can help keep it in good working order, preventing a build-up of residue that can slow down boiling and reduce its lifespan. This is particularly important if you live in a hard water area, where excess minerals in the water make it easier for limescale to form.

• Avoid reboiling - While this is easier said than done if you get distracted at home, try and avoid reboiling the kettle multiple times or opt for a model with a keep warm function instead.
