What is more energy efficient for heating water, an electric kettle or a stove?
« on: 09/06/2006 16:57:49 »
I heard the other day, that energy could be saved if you boiled water using an electric kettle and then poured it into your pot with pasta instead of heating cold water directly on the stove. Is this true?

It does work. The calories saved would be nice, but I have't been able to both 'hydrate' the pasta and keep it from clumping, even with oil. Other experiences, please?

If you have an electric stove this is definitely the case as almost all the heat from the element is dumped in the water, as the kettle is very fast and the element is surrounded by water, a lot of heat is lost around the sides with a hot plate.

A gas stove on the other hand is more complex as the conversion of gas to electricity is 30-40% efficient in itself so if the gas ring looses less than 70% of it's heat around the side, it may be more efficient. I don't know the figures so can't say for sure.
