How much does it cost to boil a kettle?

Question

Preferably the price it costs in the UK - I'm only after an approx answer! ;) thanks!

OK, I’ve refined my answer - hope this helps! The kettle is 2000W has an exposed filament and is holding 500ml of water.

Answer 1

Assume the kettle is 2500watts Thats about 25p per hour. It takes about 4 minutes to boil, so 60 divided by 4 is 15 hence 25p divided by 15 =1.7p to boil a kettle

Answer 2

I'm rubbish at maths so you'll have to work it out;
The rating is watts per hour.
Time how long it takes to boil in minutes.
Find out how much each unit of electricity is from your bill.
Work out how many units it used.
Times by the price per unit.
Get a calculator.

Or switch off everything else and read the meter before and after boiling the kettle.

nicely, in the two situations you attempt to shop up warmth skill. A kettle runs approximately 2kW -- it rather is 2000 J according to 2nd. It takes 4200J to make 1kg. of water a million diploma C warmer. And all that skill is going into the water. I have not have been given any figures for the warmth potential of wheat; yet with a microwave oven, no longer all the skill you supply finally ends up interior the fabrics being cooked -- a number of it finally ends up heating the air surrounding the oven. parent approximately 1kW for a microwave oven regardless of its output, as extra moderen ones are extra powerful than older ones. working it for 2 minutes will devour 2 * 60 * one thousand = 120000J. An 850W oven will placed 2 * 60 * 850 = 102000J of warmth into the wheat sack. in one minute, a kettle will devour 2000 * 60 = 120000J, even though it is going to placed all of that into the water. an electric powered blanket would probably artwork out extra low-fee than the two, seeing that there are not any losses -- you're storing up warmth perfect there interior the mattress itself.

Answer 4

Boilling one kettle is relatively cheap. I've often found it more cost effective and enviromentally friendly to get as many kettles as I can and put them in a pot, the biggest you can find. Just put enough water in to cover them and put the lid on, this keeps the heat in and brings to the boil quicker. Usually it costs less than a fiver

Answer 5

I suupose it depends on the kettle and the volume of water in the kettle too!

Answer 6

A watched kettle never boils....

Answer 7

that depends on loads and loads of things... such as the heat source, the type and amount of fluid in it, the material of the kettle itself...etc you need to be more specific
