Talk:Teakettle

Most house hold kettles are designed to take a maximum of 1.7l of water and no more. Why is this the case?

What about the stopping mechanism of the electric kettle. Seems to me it is more tricky to do than first thought. I think the most basic kettles have a dripping stop mechanism by letting water vapour condense on the lid and drip onto some detector. At least it explains why the kettler keeps boiling if you lift up the lid and why it also don't stop immediately when it starts boiling, but continues 5~6 seconds. Of course this depends on the model.


 * When we did it as school, they told us it was by two pieces of metal glued together which expand at different rates, positioned so that they complete/break a circuit when they reach a certain temperature, probably 100C. There would be a slight delay as the heat transfers. Skittle 12:06, 20 July 2006 (UTC)
