When you switch a kettle off it doesn't stay boiling for very long
does it.

No reason why it should - if you only boil enough for your immediate
needs.

That can't be done

Even sillier than you usually manage.

I do that all the time, in the microwave, in the cup I will drink it
from.

That figures, I've rarley done it and for me the tastse is differnt.

Because your kettle is adding **** to the water, most obviously the scale.

As I said yuo always have to biol more water than you
need for the cup or vessel you wish to drink from.

As I said, what gets lost in the boiling is a trivial part

No it isn;t because to boil water you need to put in a lot of energy,
something to do with the latent heat of evaporation.

I wasnt talking about the energy there, just the water that gets lost.

If what you want to end up with and you can allow for that
anyway by putting enough water in the vessel you want to
drink it from so that it has what you want after it has boiled.

as I said you need more water in the kettle than you are planing on
drinking.

And you need **** all more than you are planning on drinking
when you heat it in the microwave in the vessel you will be
drinking it from.

I use a cordless kettle, so if I want to make one cup of tea I get the mug
I will use fill that with water and put that in the kettle then boil it.
If I want two mugs I put two mugs of water in ... see how this works
could you work out how many mugs of water I'd put in my kettle if
I wanted to make 3 cups of tea. ?

Too much farting around. Makes more sense to mark the kettle which
has a proper gauge on the side with where you need to fill it for the
number of mugs of water you do often.

Now remmeber what I said about adding more water than you will be
drinking....
So when I fill a mug up with water there's is more water in that mug than
there will be when the water is HOT. Because :-
1/ because of the volume of the tea bag I can't get the same amount of
water in there plus tea bag..
2 I have milk so when emptying the boiling water in to teh mug
containing the teabag I have to leave about ~15% from the top lip so I can
put the milk in.
3/ I also allow for stiring & sugar so again I don;t fill the cup up with
hot water.
4/ I have to carry it from one room to the next so again I don't fill the
mug up with hot water+milk.
5/ another reason I take the water to the kettle rather than the kettle to
the water is because my previous kettle became fault due o the central
connection bit it seemd to fail before the eliment and on a few occasions
sparked.

None of that **** when you heat the water in the
mug in the microwave and drink coffee instead of tea.

If you've any sense you'll also notice that things like tea
leaves retain water so agin you have to allow for that.

But you dont if you use instant coffee.

I don;t use instant coffee to make tea.
Also instant coffee also takes up space in the cup,

Wrong, as always.

and it usually needs stirling too.

Nope, no stirling required. Even plastic works fine.

and any steam coning out reduces efficiency,

Not by enough to matter.

enough to not make teh kettel 100% efficeint.

Duh.

teh more steam that comes out teh lower the effeciancy

So you have a kettle which stops heating as soon as any steam comes out.

Not exactly rocket science.

and the more it is costing for that cup of tea,

Not with a properly designed kettle.

which is why I wouldn;t leave the kettle bioling for
10 mins in an attempt to get the water hotter.

I dont believe you.

but I don't believe those taps are as efficient as a kettle anyway.

Corse they aren't, because they have to keep the water hot
for when you turn on the tap and so lose some heat that way.

But they will be quicker so it depends what's important at the time
and for most a fast way of boiling water is quite important.

But most find that the time with a decent kettle is fine.

Provided the kettle has enough power like my 3.1KW ,
which can biol a cup of water faster than my microwave can.

Irrelevant to that **** of yours about boiling water taps.
