The little spout is for precision pouring over the ground coffee? It must be an American thing
It's popular roots are Japanese, and most of the pour over kettles are Japanese. It's popular the world over these days.

Only on ASR.

I know, right? Formulas? Online calculators?

All you need to know is that it takes 1 calorie to heat up 1 gram of water by 1 Kelvin or degree Celsius (by definition), that 1 calorie is 4.18 Joule, and that 1 Joule equals one watt second. The rest is just arithmetic.

A resistor immersed in water is of course the most efficient way of converting electrical into heat energy (100%), and the only energy losses of a water kettle are through its walls to the surroundings.

The calculator takes care of the unit conversions, which is convenient.

Between calories and Joules?

I’m not complaining. I’ve seen online calculators for converting hours to minutes…

Watts, but yeah. I don’t retain any of that stuff, because I don’t use it every day. Plus I had Fahrenheit temps and metric volumes, and it did all of it at once.

Well, not that easy. The specific heat of water changes with temperature, that's why you must define the calorie at a given temperature.
But yes, all that is tabulated since centuries? ago, so a calculator could do the job.

Yes, but only if you need to be precise to two digits after the decimal point. We don’t usually assume the mains voltage powering the kettle down to that accuracy.

Just made a lovely cup of tea, the way I normally do - put the teabag in my insulated mug, hit the buttons on the Keurig for 8oz, and about a minute later (I didn't have a stopwatch), it's ready to steep.

We do have an electric kettle, which my wife uses for other things, like sanitizing small items. It takes a good bit longer, because she usually keeps it full of water, so I don't use it for tea.

Get ready for some remember when we used to use natural gas stories. They just banned it for new construction in my county. No stoves, furnaces or dryers, no hook-up.

I just love Qalculate (Swedish locale, sorry for the decimal separator ;) ):

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.
Nice, I use the pour over stuff from "Melitta". I haven't reached the Chemex level

So - I tested our "Melitta" branded kettle today. :)
1.2 L of fresh, unfiltered tap water (well water, no chlorine or other sanitizing agents) took 4 min 55 sec to boil.
Pot's power draw is rated at 1500 W.


PS Y'all know, I reckon, that there was an actual Melitta.

She should've had a daughter & named her Mercedes. ;)

I've seen it as well. Why this kettle?

Dang! I forgot that one detail! :eek:
Our house is right at about 1000 feet (305 m).
I... ahem... could've noted the air and water temperatures & barometric pressure... I am a little rusty. :(
