This is AI’s perspective so it must be true .. 
“2,200 watts to boil water, a Quooker with high-vacuum insulation only uses 10 watts”
On the face if it a 2200w kettle boiling 8 times a day taking 3 min to boil uses 0.88 units of electricity per day, vx 10W x 24 hr =0.24 units BUT what AI has missed, is that 10 W is just keeping warm: there will be an extra very high power demand while the tap is being used, I don’t know if also for a period afterwards if a lot of water is used.
This just shows how important it is to never trust what AI says!

My Ninja kettle can boil a mugful in 60 seconds.
Suzuki kettles are different.

When you are retired does it matter whether it’s six seconds or six minutes? I like the look of our Dualit classic kettle and long may it keep us in boiling water.

Out of curiosity I checked AI to see how accurate it was with some property related legislation questions. Not to be trusted as a lot of the info given was way out of date. it’s definitely in its Beta phase at the moment.
I dont think it’s too accurate with kettles either.
My point being is I can boil just enough water very quickly.
I want a rolling boil on my Earl Grey which is something that I don’t think the Quooker can do as there will be cool or cold water in the downstream pipework.
My Dualit went up in smoke, sparking and everything, threw the trip! Bosch here now with variable temperature control!
Yes, very dangerous to use AI for anything yo do with legislation.
I recently wanted yo look up something about my amp. AI, now Google”s first hit, told me it is a valve (tube) amp. I’m still trying to find how to access them in readiness for eventual renewal, but they seem to have been cleverly miniatured and disguised as transistors. But it would explain the heat output!

Incidentally, just a month ago Which? published a comparison and assessment of boiling water taps, so for anyone in the OP’s position if could well be worth reading before committing. A comparison of electric kettles was published at the same time.

I used a Japanese kettle pot for years. Just fill it once a day and hot water at the press of a button for the precise type of drink you brew most, 60, 75, 90 or boiling.
But since moving to IH stove with a fast boil button I’ve gotten rid of the kettle pot. It will boil water so fast the lid will fly off the kettle if you aren’t watching. It’s boiled a pot of cold water in a minute while I’m still grinding coffee or measuring tea leaves.
Smaller number of really good appliances beats installing or buying additional things.

May I ask what types of pan you use please?
Just a Kalita goose kneck pot for boiling 1.3L of water. Certified for low voltage IH but I shove it on my high voltage one with no issues. Other regular IH certified cooking pans will similarly boil water pretty fast. It’s not really the pot or pan (though for IH it needs a thicker base) it’s the quality of the IH. My old Panasonic stove was pretty good but it took a few mins to boil with the same pot. My Miele one just blasts high current to a single burner for boiling.

The correct water temperature for brewing Earl Grey is 98 deg or slightly lower, water at boiling will scorch the tea leaves leaving bitterness

Twinings say “freshly boiled water 100°”.

Fortnum & Mason recommends 98C.
Is the 100C versus 98C the critical criterion for choosing between a kettle and a boiling water tap?
Best regards, BF

Generally all red and black teas will be okay at boiling and to be honest, water struggles to stay at 100C long enough to still be that temp in the time it takes to carry the kettle over to the teapot where it will often already be 98 or 97C.
Far more critical for a decent brew is the shape of the teapot and letting the leaves circulate via convection during the brew. And whether you like at brewed as directed or significantly stronger, always remove the leaves or pour the tea before the 5 minute mark. That’s the threshold at which a flood of bitter tannins are released ruining your cuppa.

We have a Quooker boiling water tap and have in general been very happy with it. The other day it stopped working - dreaded flashing red light that means it’s over heating, very probably due to limescale as we live in a very hard water area. The cost to fix is ££££££££. We could buy many kettles and boil then all the time for the price! I’ve decided to go ahead anyway as it’s so convenient and is already installed. We’ve has the tap for about 5 years and had it serviced once before. Something to be aware of if buying new.
