That 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.
