where do people stand on reboiling water?


Same as any other water: the surface.

£27 instore ASDA / George. Just saying.
Can you just pour 250ml of water at time or you can pour less by manually stop it? Does someone got it/know?
Is this actually better than having a kettle though?
If you have a kettle, are able to put in one cups worth of water and let it boil then probably not.

Surely this uses more energy than a 1kW kettle? Fail to see how it would be more efficient..

Freshly boiled water, best!
My TASSIMO T40 has a 2L capacity, and a disc that enables me to deliver JUST water in seconds. The Tassimo "water disc" has 4 barcode settings of 150,250,350 & 450 ml. It's perfect for NORMAL tea & coffee, but obviously when I fancy something special, a Latte for example?.

My point is, that since you can pick-up a Tassimo for between £30-£40 (with 2x£10 vouchers, 2B used against drinks purchased from Tassimo) why restrict yourself to a machine that ONLY delivers hot water?

Yes you can stop it pouring the full 250ml


Quicker and more efficient than a kettle....... unless you make more than 1 or 2 mugs at a time which becomes a pain

Heresy! It is all about the dissolved oxygen to give your beverages flavour, reboiled water means you have boiled a lot of that off.

Beethoven's 9th is more like it! Fill up those lungs for the choral verses with vigour!
Half tempted to mention bleeding the radiator is an on tap source of ready boiled water for cups of tea.
I’m looking for good deal of the VKJ367, or equivalent filtered water.

if you want a kettle to boil 1L of water and this to boil 1L, they will use the same amount of energy. This is more efficient if you even slightly overfill your kettle though, as I know I do when making a cup of tea. The kettle ends up boiling 400ml while this boils 250ml exactly, so this takes less energy. Do that 72 times and you've cost yourself an extra 15p in electricity so this might take a while to pay off.

Nope. The power just tells you the rate at which energy is transferred to the water. It requires the same quantity of energy to boil the water regardless of how fast the energy is transferred. A 1000W kettle uses just as much energy to boil a cup of water as a 2000W kettle. It just takes twice as long.

Kinda like if you use a slow flowing tap to fill a bath. It takes just as much water to fill the bath as a fast flowing tap. Just takes longer.

The energy saving from these devices is entirely down to only heating the water you will actually use. The potential energy savings here are not collosal, but might cover the cost of the machine. If you boil a kettle from cold 20 times a day, each time with one extra cup of water that you don't use, you are wasting about 0.5 units of electricity a day. About £25/year. I would show my sums, but it is early and frankly if anyone has bothered to read this far in this post they doing well. It's all about specific heat capacity of water. Here endeth the Christmas Eve physics lesson.

Sorry, didn't see this while I was composing or I probably wouldn't have commented.
The description is wrong, it should read;
Dispenses luke warm water at the touch of a button, don't waste your money folks, mine went back.
I've had the bigger version for years. It's a pain when we have ppl round but for just me and the wife is great.

9th?, you can keep it. Good tip about the radiator, mind.

Just wait till I get to my laptop........ Spreadsheets, scatter graphs and a PPT presentation.
This is a very noisy machine stick to kettle much quieter more efficient at boiling water

Further info, a kettle (or a heater) is the most efficient electrical appliance that you will own. As all the energy it uses is transferred into heat with virtually no losses.

physics lesson: you cannot make or break energy, only convert it into another form.

http://hotwatermagic.blogspot.co.uk/2013/04/destructive-myths-dissolved-oxygen.htmlhttps://www.reddit.com/r/askscience/comments/12lz2q/about_boiling_away_oxygen_from_water_when_boiling/


Qudos to you for looking into this and adding the links. So I've read those and I'm not totally convinced to rule out Oxygen. Only two studies are mentioned in those links which use scientists as the taste testers. In the past I've read descriptions from tea testers (anecdotal perhaps) that state that they can definitely taste a difference between a reboiled cup and a freshly boiled.

So all evidence states boiled water tastes different to fresh and especially if from a fresh stream. The other links specified that carbon dioxide maybe the cause and the other speculated nitrogen. Without talking about the differing partial pressures of the gases, the concentration of dissolved nitrogen seemed to be far too low, but could be tested by boiling some water, tasting and leaving it in the fridge for a couple of days (70% of air compared to 20%) plus gassing is an exothermic process so cooling the liquid would speed things up. This may also introduce Oxygen back in, so can't say for sure but if it works it is one of those.

The carbon dioxide theory could be tested by continuously blowing say every few hours or so for 10 minutes through a straw into the bottom of a glass of cooled water that has been boiled and tasted. But when you did a similar thing as a kid it made the drink taste worse but could have been because you were warming the glass up.

It could however be anything that is commonly dissolved in water not just gases. But you will still notice the advice with Britta kettles etc. Unsure exactly what the filters catch and how good they are.

Anyway, those are my thoughts for Christmas haha!

Interesting, I wouldn't say all the energy because I wasn't aware of any system where 100% electrical energy is transferred into the same amount of heat energy by 100%. You would lose some heat to heat the heating element as well as resistance in the wires, fuse etc. Not to mention the sides of the kettle, but I get what you are saying.

Water has quite a high specific heat capacity (c), q = mc^T. So heat is not as efficiently transferred to water as it is to other fluids. A central heating system that uses supercritical CO2 would be cool lol. But yeah, I think you are right about it being the most efficient in the home.

Hmm LED light bulb is not as it is a resistor... Hangon... Anything operated by hand is the most efficient, Pepper mill! Haha not electrical I know. Hmm got it...

Sandwich toaster! The metal / ceramic plates heat up faster than water and then we directly in contact with the bread! Hehe
Brilliant especially for visually impaired people who can't see how full their mug is. As long as the mug takes more than the machine throws out, you wont overfill again. I know there's a "beeper" system that goes over the side of the mug to tell you when it's full but many people can't hear that either, so the one cup thingy is perfect.
