By using energy saving kettles, you will help to reduce CO2 emissions and save money. In an average house in the UK, people boil water 7 times per day. On average a kettle uses the same amount of energy to boil a litre of water as it takes to run a fridge for about seven hours, so it’s a good idea to boil only as much water as you need.

A slow-boiling kettle isn’t necessarily the most inefficient one. Some kettles waste energy, continuing to boil for up to 10 seconds before the automatic cut-off switches the kettle off – a period we refer to as 'overboil'.

Eco friendly kettles uses 31% less electricity to boil water compared to a standard kettle. It works by boiling exactly the amount of water you need and no more thus saving you money. It does this by holding cold water in an upper chamber before allowing you to release exactly how much water you need to boil into the lower chamber.

There are many brands that offer eco-friendly kettles; however, Eco kettle is the only brand of kettle that has the official Energy Saving Trust Recommended label.

The Eco Kettle cost approximately £30, although you may pay up to £60 for the latest version. The price is higher than the standard kettles, however if you enjoy several cups of tea or coffee a day you’ll soon make your money back.

In Britain we drink 229 million cups of tea and coffee every day. In fact, about a quarter of all electricity used in domestic cooking is consumed by electric kettles. In a test it was calculated that if we all used the Eco-kettle it would save 697,000 tonnes of carbon dioxide annually compared to a standard design. With all then climate change issue, it is essential to understand that our domestic decision can have an impact on the environment.
