They seem to have more power, but do they use less electric. Link to comment Share on other sites More sharing options...
Obelix Posted January 18, 2018 Share Posted January 18, 2018 A little bit of working out.... you can raise water from 20C to 100C at the rate of 10ml/sec for a 3kW heater. So for a 250ml cup, it's going to be a half minute to fill it up. Link to comment Share on other sites More sharing options...

Is there more than one brand of kettle? My sister has one of these. In fact, they're on the second one after the man fitting their kitchen managed to kill the first one by unknown means. They like it. It's certainly fast and convenient to be able to press the button and walk away then come back to a mug of boiling water. However, my favourite mug is about 1 and a half measures of water, which is a pain in the bum to measure out, and filling up a pan of hot water for cooking involves pressing the button half a dozen times and waiting while it dispenses each cupful, which would irritate me if it was mine full time.

There is a more expensive version that allows you to adjust the volume dispensed each time, apparently upto a small teapot-full. http://www.breville.co.uk/breakfast/hot-water-dispensers/hotcup-with-variable-dispense-gloss-black/VKJ318-01.html Edited January 19, 2018 by cgksheff Link to comment Share on other sites More sharing options...
Mikes10 Posted January 19, 2018 Share Posted January 19, 2018 (edited) My jug kettle requires 2.5 cups of water to cover the element. The element is rated at 2.2kW To boil 3 cups of water (675mL) takes 2 minutes 6 seconds. Present cost of electricity 13.02 pence / kWH (including VAT) Cost per second = 13.02/3600 = 0.0036167 Cost to boil 3 cups of water = 126 * 0.0036167 = 0.456 pence. ( Corrected, initial calculation was wrong ) Edited January 19, 2018 by Mikes10 Link to comment Share on other sites More sharing options...
zach Posted January 19, 2018 Share Posted January 19, 2018 £30 or £70 for a kettle? £30 I might go for but £70 is a tad OTT. My main concern would be... What would I use to rinse my rice off with? Link to comment Share on other sites More sharing options...
alchresearch Posted January 19, 2018 Share Posted January 19, 2018 I've used a few of these. I always found that the water is never boiling. I leave the teabag in for about five minutes to brew. But the tea was never as warm than if I'd used the kettle. Link to comment Share on other sites More sharing options...
Flexo Posted January 19, 2018 Share Posted January 19, 2018 I've used a few of these. I always found that the water is never boiling. I leave the teabag in for about five minutes to brew. But the tea was never as warm than if I'd used the kettle. I had the same experience. These things work by passing the water over a thermoblock. The water is hot enough for coffee but not for a good cup of tea. The thing didn't last long before it broke. At that point the environmental waste outweighed that of boiling a little too much each time in a conventional kettle. If I was to buy another "instant boiling water" thing then I'd use a plumbed-in model which would be built to a proper quality. £30 is overpriced for what that Breville thing is.
