Do you boil only enough water for your cup of coffee or tea or are you the person who can’t resist keeping the kettle filled to the top? The Eco Kettle caters to everyone. It features a central reservoir that you can keep filled to the brim and a central valve button in the lid that releases only the amount you need into its boiling chamber, from one to eight cups - saving electricity, time and even water.

It's estimated that most of us use twice as much water as we need when we boil the kettle - that's twice as much energy and twice as much time.

Underscoring the importance of saving energy and using water efficiently, the UK's Department of Environment, Food and Rural Affairs (DEFRA) stated "If everyone boiled only the water they needed to make a cup of tea instead of 'filling' the kettle every time, we could save enough electricity to run practically all the street lighting in the U.K."

Independent consumer trials directed by the Energy Saving Trust, showed that the Eco Kettle used over 30% less energy than standard kettles.

Other features of the 3kW, 1.5 liter capacity Eco Kettle include steam control and boil-dry protection, a washable limescale filter, a locking lid and 12 month warranty.

It won't solve the problem of your housemate or colleague suddenly deciding they'd like a cup of tea too, thank you, when you've already set it to boil, but saving the world isn't always easy...

The Eco Kettle retails for £29.95 (just under USD$50) at the Ethical Superstore.
