With induction stoves getting more popular that’s less of an issue nowadays.
- swarnie 3y agoStill, putting the stove on to make a cup of tea seems wrong.
- ThatMedicIsASpy 3y agoyeah but it is 5 times faster than a kettle
- the_mitsuhiko 3y agoThat seems purely emotional. An induction stove heats faster than a kettle at almost the same efficiency.
- Tuna-Fish 3y agoNo, it really does not. A typical induction stove has ~2kW of power on each element, and is ~20% less efficient at heating water than the resistive kettle. This makes it about half as fast at boiling water.
- oblio 3y agoYou made me check and adjust my other comment: https://www.aeg.co.uk/kitchen/cooking/hobs/induction-hob/ikb64401fb/ https://www.aeg.co.uk/kitchen/cooking/hobs/induction-hob/ikb... 3.7kW for the main element. Also, why would it be less efficient? Due to the distance?
- Tuna-Fish 3y agoNote that the 3.7kW element can only provide all that to a single vessel if it covers the entire area of the element. The resistive element submerged in the water dumps very nearly 100% of energy into the water. The stove heating the kettle has many more sources of loss, but mostly that it first heats a piece of metal, which is not fully submerged in water.
- the_mitsuhiko 3y agoIn theory, in practice the induction heating on a regular pan is faster than my kettle by almost three times. YMMV on type of kettle and induction hob used. But it generally means that if you live in the US and you have an induction hob, there is absolutely no reason to buy a kettle.
- rightbyte 3y agoYou might want to decalcify your kettle. Edit: Wait. Are you using a frying pan to heat tee water to make it faster?
- the_mitsuhiko 3y agoMy experience with US induction stoves is limited but I believe it can also deliver 3.5kW on boost. My induction stove boosts to 3.8kW for heating which beats my kettle significantly. I also measures the efficiency and it’s quite comparable.
- Tuna-Fish 3y agoWhat is the power of your kettle?
- the_mitsuhiko 3y ago2200 Watts.
- londons_explore 3y agoA British kettle on 230 volts boils enough water for a cup of tea in about 45 seconds. (3 kilowatt heater, 300 ml of water, theoretically takes 33 seconds, but slightly longer because it has to heat the body of the kettle too)
- bloopernova 3y agoI wonder if it's possible to replicate that circuit in a USA house but still stay within code. I'd love to make my tea faster!
- londons_explore 3y agoInstall an A/C socket in your kitchen. Then buy a British 240 volt 3 kilowatt kettle from eBay and wire on a US A/C plug (NEMA 6-15) - hooking the brown and blue wires from the kettle to the two line pins, and the green/yellow wire to ground. This would be both code legal, safe and functional. It would also be possible to use a clothes dryer socket (NEMA 14-30), but you should install a smaller than usual breaker for the circuit (15 amps), since the british kettle normally has a 13 amp fuse in it's plug, but a NEMA plug does not contain that.
- bloopernova 3y agoSweet, I had no idea it would be that straightforward. Thank you for the information!
- TheSpiceIsLife 3y agoI use a Panasonic flatbed microwave to heat precisely the volume of water I want by filling the tea cup(s) I want. Two minutes on high (1100 watt microwave output from, IIRC 1800 watt input) per cup. So usually two minutes for the one cup of I intend to drink. Every electric kettle I’ve ever owned has a minimum volume of at least two cups. Who bother heating two cups if I’m only going to drink one at a time. Tasmania (AU), 240v / 100amp supply to residential is standard.
- wil421 3y agoIsn’t that the traditional method with a kettle that whistles?
- CalRobert 3y agoTo be honest for the many years I lacked a proper stovetop kettle it felt wrong to not have the whistle. Though I also missed the auto-shutoff.
- googlryas 3y agoHuh? That's how people did it for all of eternity until about 75 years ago.
- bemusedthrow75 3y agoWe drink an unbelievable amount of tea. Firing up the hob each time would be silly, when you can fill a kettle to the minimum and have boiling water in an incredibly short time. Not much more than half a minute with a good modern kettle.
- rootusrootus 3y agoThat sounds like a good use case for an insta-hot tap. No filing anything, always ready to go.
- bemusedthrow75 3y agoIt does in theory. There are a few taps in the UK that are marketed as being able to produce essentially boiling water (which is what our typical tea bags require). Though we tend not to put quite so much money into our kitchens. And we would wear those things out, I swear! :-) I think Americans think British people drink tea out of poshness, when it is the opposite. Most of us also like a posh tea now and then, some of us drink expensive leaf teas... but the majority of what we drink is optimised for fast brewing off boiling water: tea that goes black in the mug in thirty seconds in boiling water. There is a concept here of "builders tea" -- the kind of thing a builder drinks -- which is sort of the functional equivalent of cheap electric coffee-pot coffee. That is, it's the kind you know isn't the best, but you will still drink it, and that cuts across all class lines. [0] There is a parallel thing: the "tea urn", which is like an enormous samovar with a lever -- that you still will see in industrial canteens and at church coffee mornings and at gatherings that aren't at cafés or restaurants. Those things actually need a different kind of tea, which brews more slowly and at slightly lower temperatures. The end result is a bit like builders tea. But we wouldn't bother with them at home. [0] We do absolutely drink coffee at home, but aside from appalling instant coffee we tend to skip over the coffee-pot coffee in the UK, to slightly more expensive ways of making coffee or to dreadful Nespresso machines. You'll see more of those or Bialetti mokas here; old style electric coffee pot percolators are now rather unusual. But Alan Adler's Aeropress particularly caught on here among coffee nerds, because that is really compatible with electric kettle life.
- ikekkdcjkfke 3y agoNobody heard of Quooker?
- mhandley 3y agoWe have an induction stove too and it's great. But the kettle is still significantly faster at boiling water.
- oblio 3y agoI'm kind of surprised by this. An induction stove turns the entire kettle into a resistive element so water boils super quickly. At least with EU induction stoves, so 230V.
- mhandley 3y agoOurs is a Smeg model. The two large rings are 2.3kW, with a outer booster ring to 3kW. The problem is if I'm just boiling water for my tea with a saucepan, only the inner ring is triggered. I can put a large pan on there and get 3kW to match the 3kW kettle, but then I've got to warm a large metal pan too, whereas the kettle has very little thermal mass and is lightweight and easy to fill too.
- brewdad 3y agoA properly sized tea kettle would solve that but since you already have the electric kettle there’s no sense in buying a new stovetop vessel until the electric kettle burns itself up.
- rootusrootus 3y ago> At least with EU induction stoves, so 230V. US induction cooktops/stoves are almost always 240V, unless you get a little countertop burner. > I'm kind of surprised by this. As am I. The first time I put a small pot of water on my induction cooktop and turned it on maximum power, I laughed out loud. If I'm only doing enough for a cup of coffee or tea, it starts boiling so fast you don't want to step away.
- oblio 3y agoOne small thing I'd like to add, I actually forgot about this. > US induction cooktops/stoves are almost always 240V, unless you get a little countertop burner. EU induction cooktops/stoves are actually 380/400V. It doesn't change much, because the amperage might be lower, I don't know. I just wanted to add that bit of trivia :-)
- Tuna-Fish 3y agoAn induction stove is still really inefficient at heating water, compared to an electric kettle with the resistive element in the water and 3kW of power.
- andersa 3y agoThey should make turbo kettles that hook up to 3 phase power like a stove. That seems like it would be fun. Why stop at 3kW, when you can have 11?
- kccqzy 3y agoNow I want a kettle designed for a J1772 EV plug. Why stop at 11kW when you can have 19kW?
- the_mitsuhiko 3y agoThere is a small difference but not much. I compared my 230V Kettle with my 400V induction stove and it’s within 5% or so. Obviously it depends a bit on what pot you use. I’m guessing most losses come from the lack of insulation on the metal pot.
- oblio 3y agoWhy? I'm not sure I understand the logic. For example this: https://www.emag.ro/plita-cu-inductie-aeg-hob-hood-60-cm-ikb64431xb/pd/D0BF69MBM/ https://www.emag.ro/plita-cu-inductie-aeg-hob-hood-60-cm-ikb... (in the EU), at max power can supposedly reach 7.3kW. Edit: Checked per element, max 3.7k, more than enough anyway.
- vel0city 3y agoFor the induction cooktop, there's circuitry to drive the induction system, which then creates magnetic fields, which then interacts with the metal pot, which gets hot and heats the water on one side while radiating heat into the air on the other. There's a lot of stages for losses here. On an electric kettle, there's just a heating element, often directly bathed in the hot water. There's absolutely less losses with the electric kettle, so for a 3kW kettle and a 3kW induction cooktop the kettle is slightly more efficient. Slightly.
- doublesocket 3y agoMy in-laws have fried three different induction hobs boiling a kettle on them. Good quality brands too, they just can't seem to cope with frequently being set to max.
- myrmidon 3y agoAre people actually using induction stoves for tea, though? For me, a big selling point of the kettle is that you don't have to clean it and stow it after every use, so I would still use the kettle even if it was slower (maybe no longer for pasta or when cooking in general though)... edit: I guess you could just get a teapot that is induction-compatible, didn't think of that.
- PrimeMcFly 3y agoYou don't really have to clean a pot either if you just used it to boil water.
- fireflash38 3y agoMostly just descaling, but cleaning it with soap and water isn't going to do much about that - you need an acid like vinegar or citric acid.
- bowsamic 3y agoThere's no chance I'm bothering with getting out a stovetop kettle every time I want a tea. Far easier to just have a separate kettle
