How long does it take to boil a kettle in USA?

[F1308]

I hear electric kettles aren't much of a thing over there and you are on 120v mains anyway, so...how do you boil a kettle and how long does it take?

Since latitude and longitude are surely out of the equation, let me switch tools to use the "latest" developments and then I can say from daily.practise that some 250-300 CC (1/4-1/3 of a liter) needs 200 seconds when water taken from a jar at around 18-21 Celsius and placed in a ceramic cup to boil at 3000 feet elevation using 1000 Watts in the power selector.

Australia water starts off warmer in the first place, and once you pick out all the spiders, it boils really fast.

Colder water could boil more quickly if conditions are conducive for the inverse Markovian Mpemba effect

No need to pick them out, that is what the spider strainer was invented for:

Still science!

What was sea level pressure that day ?

That can’t be good. Tea water needs burn-in, like cables. It needs a slow boil, and you’ll need at least 200 hours on your kettle before the tea start to taste anywhere near good.. but then: veils lifted for sure!

You're so right. When I heat water slowly, I see the veils start emerging as it gets good and hot.

Spider strainer? That's where I found the taipan curled up. Probably after snacking on the spiders, it needed a nap.

BonziBuddy2023 says:

To raise a liter of water from 30C to boiling takes 293.6kjoules, or 81.56 watt hours, and a 1200W heater will do it in 4.08 minutes, ignoring all the problematics.

Sounds about right.

Boiling varies with pressure.
Pressure is related to elevation and sea level pressure at the moment.
Local winds at valleys and mountains do have its own effect.
Then your own house can have positive or negative pressure builds, to be taken into account when operating a chimney...

You’ll need about 5.5kW to boil 1L of water in a single minute with perfect efficiency. That’s a lot even for an induction boost stove.

Maybe you can do half a lite in a minute…

Well. 3.7 kW (an induction stoves' max power) heats 1 l. of water (from 10 °C to 100 °C) with 90 % efficiency (induction stove) in about 114 sec.

Edit: EU 230V 1 phase / 400 V 3 phase.

I know it is not very much related, but since it took me some effort and time, I will announce it right away...

Microwave cooking times...

Weight times 10.
So 400 gr needs 4000w.

Is it meat? Coefficient 1, so 4000w remains.
Is it poultry? Coefficient 0.9, so 4000 turns 3600.
Is it fish ? Coefficient 0.8, so 4000 is now 3200.

Now you want it SLOWLY, (not extremely slowly) so let's say your microwave offers 1000, 600, 360, 180, 90...

Take 180 and then cook by the numbers...

400 gr of meat, 4000w, 22 minutes.
400 gr of poultry, 3600w 20 minutes.
400 gr of fish, 3200w, 18 minutes.

This assumes meal was taken out of fridge to
equalize temperature. If not, add 10%.

I love it.

Once you cook using the same microwave, you
arrive at fix coefficients so that in the end
I cook meat, poultry and fish by approximately 5.5, 5.0, 4.5 minutes for every 100 grs.

And if you happen to buy ready to cook portions, say 400gr meat, 600gr poultry, 500 gr salmon...it will be a single calculation, and use it forever.

Tested today with my cheapo electric kettle (“ivation”). Filled it to 1.7 Liters and it took 7 minutes almost exactly to get to 212F. I have well water here, 63F at the tap.

about 815 watts or ~3000 BTU/hr

(in the US, 850 feet above sea level)

I think we can get closer to 1500 watt on a space heater or hair dryer in normal US outlets so I suppose one could do it faster, but you would need to make sure nothing else was on the circuit. Or am I thinking about it wrong?

 

[Mart68]

75 seconds to boil 0.75 litres.

UK - sea level plus 500 feet.

 

[antcollinet]

Only on ASR.

Seriously

Only here.

AM or PM?

AM, about 20 minutes before my post. Outside air temp was around 53F, humidity 86%. Inside air temp 71F, humidity 53%. I’m about 440 feet above sea level.

Now I wish I would’ve measured/weighed the water…

It will be dependant on humidity.

There are plenty of NON-TEA uses for hot water (French press/ pour over). Most people I know in America use electric kettles and it takes under 8 minutes to boil water.

This. FWIW, most people I know (selves included) who use a Chemex or similar for coffee use this kettle in one of their umpteen colorways.

I’ve never timed it but it’s quick enough.

If you have an induction table top it is likely to be quicker to boil water than a kettle. Both because of the higher efficiency and because of it's higher power.

I guess it's only 900mls capacity, so 1200W will heat that fast enough. The little spout is for precision pouring over the ground coffee? It must be an American thing, I'd never heard of a Chemex or a kettle/jug like that.

Late to the thread.

I am in the NYC area and have two electric kettles in the kitchen. Both are 1500W and of course operate on our 120V mains.

I always boil 0.5L at a time, and it takes slightly over two minutes to reach a full boil on either kettle.

This is of course much slower than the 3,000W kettle we had when we lived in London.

The pour-over coffee craze in the United States has, in my opinion, become a little too effete. I use an AeroPress, and that's my limit. I have neither the time nor the patience to make pour-over coffee, and when I have had it at others' homes, it has tended to taste less transcendent than they think.

If there were a version of Nespresso for filtered coffee, I'd be using it. (Keurig machines don't get hot enough to make proper coffee.)
