Why are kettles noisy?

Explosive heating of the water in to steam around the element

This. Water right next to the element turns into steam, rises a little into the main body of much colder water, and cools down again. This rapidly changing state makes a racket.

Could it be reduced by attaching a heat sink to the element? Or maybe something to keep the water moving as kettles get quieter if you slosh them around.

You could make them quiet, but it would cost money and make them complex. Most people want cheap and simple hence thats what we have.

Plastic kettles boil water more quietly than the stainless kettles.

Because more science.

Not very instant. It was about 20 seconds before anything came out, and that much water in an electric kettle would take about 20-30 seconds to boil!

In one of the hotel rooms we had in Tokyo, there was a kettle that was incredibly quiet. Played a nice little tune when the water was boiled. Silly thing to be impressed over, but I was nevertheless.

HTH.

Watched the video and could not believe how long it took for the water to flow. What is the complete opposite of a concord moment.

How long does your kettle take to boil water?

There must be a better way to make water hot than just to put a hot thing into it. What about a microwave kettle?

Not so long that it would justify another completely unnecessary gadget in the kitchen.

What about some cheap and easy way of circulating the water so that the entire volume of water heats up more evenly?

Good idea - something that would turn the water at the bottom to steam, causing it to rise in the body of water and move the colder water at the top closer to the element, thereby turning that to steam?

That sort of talk would have had you burned at the stake not too long ago.

Har-de-har-har!

I meant so that the water right next to the element doesn't immediately turn to steam (which we've already established is what causes kettles to be noisy).

If the water circulated more BEFORE any had a chance to turn to steam, the temperature differential across the entire body of water would be more even.

[jammy_basturd]

I guess it depends whether people would be willing to pay a small premium for a "silent" kettle.

What if a kettle was ring-doughnut shape, on it's side with the heating element on one of the sides that's vertical. Then you might get some decent convection currents going without moving parts.

Their definition of instant is very different from mine.

I'm not that old fashioned in fact I nearly wet my nickers with excitement when I first saw it. Just to bloody slow.

Would a "double glazed" kettle work ? A bit like a Thermos Flask with a heating element, I suppose ?
