Thanks. Looks fairly DIY-able
Then you're into *real* money!
Good point about hand-washing, though!

I too was brought up to believe that. But I've recently being using filtered water for tea and coffee to get rid of the chlorine taste in our mains water. If there is some left in the kettle, I've been topping it up rather than wasting filtered water. Frankly, I can't tell the difference between that and always using freshly boiled water.
I must admit, neither can I, except when it comes to herbal tea. I never got what the big deal was, always tasted like hot, coloured water. But I've noticed if I use fresh water they start to taste of something. Still, could be physological.
Oh for f*ck's sake, how many times do I have to repeat that the boiler under question uses a *pressure* vessel. So the water is in a sealed container and *isn't* boiling.

None. I heard you the first time.
But I had gone over to a kettle as a question - and to try to find the truth behind the oxygen issues.
The discussion widened to tea making in general. Chill out.
Well, as it's not therefore boiling, the arguement is void anyway.
I was responding to Alexander's comment about water that's been kept hot not making a decent cuppa due to "boiling". I got the impression that he hadn't grasped that the water can be held at a 100C (or higher) without actually boiling.

Put the sugar in your tea-water before you boil it? Good boiling point raiser. :-)
We've had an "Insinkerator" for a couple of years. It has a large temperat ure knob on the front of it, which we have set at 98 degrees C (from memory ).
We're pleased with it. The tap has two levers - one hot, one cold. The fi lter is before the tank / tap so filters both the hot and cold.
Before the Insinkerator, we used a Britta jug filter to fill the kettle, so lely to prevent the scum film on cups of tea. This was very effective, and the filter / insinkerator combination is equally effective. No scum.
It's an attractive and convenient device that has replaced the Britta jug f ilter and the kettle. I try not to think about the £250 it cost me on eB ay...

That's an interesting assertion. Do you have a source for it?
(There's _less_ of most gasses, but not none)

Hi Roger
The Quooker Combi could actually be a better solution for you
Please don't consider fitting a water softener to this device as it will ru in the Quooker and fail to improve the taste of your water and will not rem ove lime scale. I am not a fan of these softeners, not least because they u se sodium and to drink high sodium content water isn't good for us, but i a gree softened water can be of benefit to other appliances like the dishwash er and washing machine.
I would like to recommend fitting a scale reducing filter to your Quooker which will take away the lime scale and give you the best tasting water pos sible.
If you would like to read a blog post I have written about the affects of l ime scale on the Quooker tank and tap please visit: http://firstclasswater. com/limescale-quooker/
and if you would like to talk to Luuk Spolesltra a specialist in Quooker in stallations and maintenance then call us on 020 7377 8563 where we can talk through all the Quooker options with you to find the right one.
Quookers are great and you are right to think laterally if living in a hard water area, but we can work with this and also warrant against lime scale problems too, so all workable.
Kindest regards

er, no - it's what we were told in ONC chemistry at Tech. (or it might have been HNC - 40 yeras ago now).
ISTR that boiling is dfined as being when the saturated vapour pressure equals atmospheric pressure (hence the variation with altitude/pressure). Even 'water gas' (steam) no longer dissolves in the water (OK, I'm waffling, somebody what knows should be along soon), hence the bubbling.
As an aside, I once bought a cheapish kettle from Tescrot. First use - it had blue LEDs inside (but no fans or twin-fan cooler). When it appeared to be boiling, as shown plainly due to the LEDs, I made the tea. 5 mins. later the loose-leaf Yorkshire tea was still floating. Some thought suggested bubbles under the leaves; difficult to prove due to the size. Next time I did everything the same except allow the kettle a bit longer. There was a subtle change of tone a few seconds after the 'obvious' boiling and I made the tea then. The leaves had sunk after about a minute. I didn't repeat the 'failure' mode - when I want me tea...!

How?
I presume you are talking about an ion exchange softener as you refer to sodium levels later. If so what on earth do you think they do other than remove lime scale?
drink high sodium content water isn't good for us,
What additional quantity of sodium do you think drinking water from an ion exchange softener would add to a persons diet each day?
I did some digging, because I thought it was less, not none.
has some stuff on it.
"While heating water (saturated with nitrogen) from 25 to 95 °C, the solubility will decrease to about 43% of its initial value. This can be verified when heating water in a pot; small bubbles evolve and rise long before the water reaches boiling temperature."
and
"The solubility of gases does not always decrease with increasing temperature. For aqueous solutions, the Henry's law constant usually goes through a maximum (i.e., the solubility goes through a minimum). For most permanent gases, the minimum is below 120 °C. Often, the smaller the gas molecule (and the lower the gas solubility in water), the lower the temperature of the maximum of the Henry's law constant. Thus, the maximum is about 30 °C for helium, 92 to 93 °C for argon, nitrogen and oxygen, and 114 °C for xenon."

Aye, have a beer ;)
