My kettle boils a mug’s worth of water in less than a minute, and it takes me longer than that for even a brief toilet visit and washing of hands. I have learned not to switch the kettle on until I get back from the bathroom, otherwise I’ll be boiling the water twice.
Important factors: 1) Britain has 230V mains power so electric kettles can boil water incredibly quickly, 2) The stereotype about Brits and tea is true in my case. I get through three to six mugs of the stuff per day. 3) Hot tea must be made with boiling water. Power isn’t cheap and re-boiling the water adds up over time.
Induction hobs I think are still less efficient than an electric kettle, right? Correct me if I’m wrong. (I have both but I don’t have the know-how to measure the effect of either. Just what I’ve heard.)
Right. The hob needs to heat up entire surface of your cookware, and kettle transfers heat directly from the element below to water - only then some of that heat is dissipated.
Induction directly heats the bottom of the cookware (as opposed to regular hop heating the surface which then heats the bottom of the cookware), and from that bottom the heat is transferred through the entire volume of your utensils. And then food is heated off that.

Every thermal machine is technically ~100% efficient at producing heat, but then how much heat is spent usefully is another metric, depending on materials used (and subsequent thermal dissipation), loss in cables, etc.
If you have both, and a timer on your phone, should be easy enough to check. Put the same measured amount of water in both and see how long it takes to boil.
I used to microwave water for all sorts of things before getting an induction stovetop.
Seriously, it goes from tap water to boiling in 2 minutes. It’s a game changer.
My electric kettle does about the same. Long enough to finish a piss before doing the water things.
Never mix up things there… 😇
Too late. Dumped my tea and drank my piss.

Mine takes longer, but I never brew a single mug. I brew a full pot and I only reason I limit myself to that is because of the size of my kettle.

Not how induction works.

afaik electric kettles are the most efficient machines around. something like 95% efficiency

It would be interesting to test. quick, someone poke Technology Connections.
He already did this one, iirc induction was better for Americans without access to 240v connections.
I think it’s this one?

Yeah I meant efficiency, not effectiveness. Like power consumption vs time.
this only works if both have the same energy consumption.
this is probably not the case, so you also have to measure the energy consumption and then adapt the measured time accordingly.
