I want to boil a liter of water. Which is cheaper, using the electric kettle or gas cooker ?

Question

I live in London, United Kingdom

Answer 1

Per heating unit gas is cheaper even today, but with the water's direct contact with the electric kettle's element, it is more efficient and therefore a little cheaper.
If you can contain some of this waste such as a central heating boiler gas is cheaper, if you ignore the air that is needed to obtain combustion.

Answer 2

The electric is certainly more efficient as ALL of the heat produced by the element goes into the water.

Gas though, heats the metal pan/kettle and the air as well as the water.

However, gas IS cheaper in most heating situations.

Answer 3

I'm not sure about utility prices in the UK. A great book to get (probably on Amazon) is the Tightwad Gazette. It answers all kinds of questions just like this and will help you save a ton of money. It's cheaper here (U.S.) to use a gas stove. Put in just the amount of water that you want to boil.

Answer 4

It obviously depends on how much energy was used in producing the electricity and the gas.
My educated guess is that electricity needs much more energy to be produced, so gas is the cheaper alternative to heat things up, if and when possible.

Answer 5

Electric kettle. It only takes a few minutes while with a gas stove, you will have to wait a whole lot longer.

Answer 6

i would say gas,a kettle works out about a penny a boil.

Answer 7

With utility prices these days, it's 6 of one and half a dozen of the other.

Answer 8

You need to convert the energy required by both to BTUs and then you can make an educated decision.

Answer 9

gas

Answer 10

i would say that the gas was cheaper,
