Kettle energy saving

If you are on the hunt for the best energy-saving kettle to save you on your bills in the long term, then look no further. Typically, electric kettles are an excellent energy-efficient option - they are substantially more power-savvy than their stove-top counterparts and can also turn themselves off once boiling stops, cutting off any unnecessary power usage. While overfilling remains common, it's best to boil just the required amount of energy. Let's get into our guide for the best kettles for your needs.

Modern smart meters offer a window into our daily consumption, both in terms of water and electricity. These meters allow you to look over your kettle's frequency of use, the energy it requires, and the amount of warm water that goes unused. Particularly in colder months, our kettle's usage tends to go up. Long story short - a faster boiling means less energy consumption over time, and kettles with around 3kW wattage typically boil quickest. You can find many kettles that fit this criteria, from the best quiet kettles to smart kettles.

A study by Science Direct shed light on our national kettle habits. It revealed, "In the UK, more than nine in ten people (90 per cent) use the kettle every day, with 40 per cent doing this five times a day or more." Guilty as charged! Though the report delves deep into the science, it boils down to one main takeaway: smart kettles trump energy efficiency over traditional ones, which goes to show how much energy could be saved nationwide if we switched to more energy-saving appliances.

So without further ado, here are our top energy-saving kettles. From the best stainless steel kettle to compact appliances for your kitchen. Here are our picks of the best kettles to save you on your bills.

What to consider when buying a kettle

Kettles have long been kitchen mainstays for more than just brewing tea. From your morning coffee to instant meals like pasta, they play a surprisingly versatile role in our daily culinary routines. But what should you keep in mind when selecting one?

Energy-saving: If being eco-friendly is a top priority, an electric kettle is your best bet. They typically operate between 2-3kW. Remember, higher wattage translates to quicker boiling times. Little fact - the first automatic stainless steel kettle was by Russell Hobbs in 1955, using steam to trigger an auto shut-off, ensuring efficiency and safety.

Limescale filter: Especially useful for those in hard water regions, choose a kettle specifically designed to combat limescale build-up to ensure you have purer water.

Water level indicator: A clear indicator helps you fill just the right amount of water, avoiding energy waste from boiling more than needed.

Advanced features: If you're willing to invest a bit more, modern smart kettles come packed with features like silent boiling, precise temperature settings, prolonged 'keep warm' settings, voice commands, and even app compatibility.

FAQs: Best energy-saving kettle

How do I measure the energy consumption of my kettle?

One way to see how much energy your kettle is using is to do an experiment with your smart metre's in-home display (IHD). An IHD shows you how much energy you're using in kilowatt hours (kWh) and it shows how much it costs. Citizens Advice suggests turning off all devices, except essential electricals, then using your kettle to see how much it costs you.

If you don't have an in-home display or smart meter, you can work out how much your kettle costs to use with this equation:

Appliance Power (W) x Amount of Time Used (p/h) x GBP per kWh (0.33) / 100 = Price Per Use

As of April 2023 the unit rate for electricity is on average 33.21p/kWh.

Amount of Time must be in decimals (0.5 is 30mins, 1.5 is 90mins)

For example, if you've totted up that you use your 3000W kettle for 15 minutes a day the sum is:

3000 x 0.25 x 0.33 / 100

Rounded up, it works out at 2.5 pence a day to use a kettle.

Are smart kettles energy-efficient?

Many smart kettles come with energy-saving features such as precise temperature control, which means you only use as much energy as needed for your desired temperature. However, always check the product specifications and reviews to ensure energy efficiency.
