A:AnswerNot advisable, this is designed specifically for tea. The only real consequence would be difficulty in cleaning the kettle as it is not submersible. So you could, However a conventional pot or pan would be preferable.
A:AnswerThe sound is likely due to the swift heating process causing the metal to expand from room temp to its boiling temp in under a min. Unless you have a faulty machine that has a different issue which I can’t imagine as it’s mechanical parts a few. I do not perceive this kettle to be louder than past models I’ve owned or seen used by others. It’s likely the normal operational sound and volume shared by similar brands of the same product. Feel free to find someone you know who owns a kettle of any brand for on sight comparison:)
A:AnswerYou could, but I wouldn’t advise it. Heating milk requires a low heat with constant stirring so that solids do not stick and burn to the heated surface. This causes difficulties cleaning afterwards that involves scrubbing. Try a milk steamer instead:)
A:AnswerIt is a suggestion requesting that the specific quantity limit not be exceeded or the product will likely begin to malfunction or cease function entirely. Exceeding water level limit results in product boiling water overages out of front spout on to product buttons, counter, and or people standing near product.
