iirc kettles are still more efficient than pans when it comes to boiling water. probably due to the time taken to heat the water up. as gas is heating it up it loses more energy over time.
i'm still not sold on boiling water taps. for them to be worth it you would literally need to be using boiling water at least 5 times a day. you can get kettles now which give you a cupful of boiling water on demand too. i think the cost of them plus the running costs aren't worth it unless like i say you constantly need boiling hot water which a lot of people don't need. nobody drinks tea in my house and we already have a coffee machine. the only time we use the kettle is when making pasta or for hot water bottles.
Absolutely this. The problem with heating water in a pan is the surface area issue, vs the ability to add energy.
As things get hotter they will lose heat faster, so a pan with a large surface area and a limited ability to heat will take a lot longer to heat. Plus so much heat is wasted that just goes up and around a pan.
A kettle adds a lot of energy and its basically contained by the thing its heating so the conversion of energy used to heat is way higher.
We had one of the one cup things till recently (it was the 3rd one actually) so we (I) when it stopped working correctly ditched it.
We had a "conversation" at home, I was asked why I bought this horrible slow kettle. "Its not its a 3.1kw one" I said. What was the first thing she did? Fill it to the max line then compain it was taking 6 times longer than the old one cop took.
I tipped most of the water out and left one cup in it, lo and behold it took about 30 seconds just like the one cup. Which coincidentally also had a 3.1kw heating element.
This is the same person who wants to keep the Britta filter in the fridge so the water is at 4 centigrade, and will then complain about the time it takes to boil


(not home atm though)
