This Energy-Saving Kettle saves millions by not wasting water

It’s a big claim from a small device, but the makers of Miito, a new prototype that boils water are pretty confident.

They reckon that most people overfill a kettle every time they put it on to boil. What’s the problem you might think? But a recent UK study from the Energy Saving Trust (EST) found that 95% of people boiled their kettle every day.

Not only that but 40% boiled it over five times a day. However, the survey also discovered that three-quarters of those who answered the survey admitted to overfilling their kettles. The EST estimated that this wasted a total of £68m each year, which is the equivalent of lighting all Great Britain’s streetlights for one night.

So why do we overfill? EST water strategy manager Andrew Tucker said that people didn’t necessarily associate water with saving energy, “they think of heating and lighting, running electrical appliances or filling the car with petrol”.

“It’s all too easy to turn on the tap and not think about the consequences,” he said.

Therefore providing a solution to heating water requires a totally new and radical way of thinking, both in a technical sense and mentally.

The Miito is an induction kettle, as it uses an electrical induction plate with a rod that is then inserted into the cup. Using an electromagnetic field, the rod heats up and the water is boiled.

This simple idea is both energy-saving and brilliant, because you always know exactly how much water you need, as you can clearly see how much goes into the cup or receptacle.

You can use the Miito with any non-ferrous objects and size is no problem. It can also be used to heat up other liquids, such as milk for coffee or even soup. And the rod is easily cleaned.

The Miito does not have an On/Off switch, it remains on ‘Standby’ mode when not in use. When you are not using it, it retains a small current which is able to detect the ferrous material of the induction plate.

When a cup is placed on the plate and the rod is put inside, the full power of the rod is activated by the plate. Once the liquid has reached boiling point the rod signals to the plate and returns back into ‘Standby’ mode.

The shape of the rod also minimizes calcification, so you don’t get lime scale build up as you would with a normal kettle. It’s said to be much quieter than the average kettle when in use.

For now the Miito is in the prototype stage, but the team behind the device are hoping that after a few tweaks, including an automated shutoff sensor, that it will be ready for market in 2016.

The price is estimated to be around £80 and they are crowdfunding to source finances.

For now though, we’ll all just have to be a little more cautious when filling our kettles.
