Kettle how many amps

So to raise one litre of water from 20 to degrees Celsius requires 4. Dividing that by 2. Of course that scales with volume, so boiling 2 litres takes minutes and costs about 6 cents.

My kettle at home goes from 0. A big waste if you only need a cup or two at once. And electric radiators are the spawn of the devil. Get a reverse-cycle air conditioner, or at least a gas furnace. Actually, if you only partly fill your kettle, it will still use the same amount of power as if it was full. It will use the same amount of power, but only for half as long. All the heat from a kettle element goes into the water in the kettle. If you are using a kettle on top of a stove gas or electric , there will inevitable be more heat wasted which is not contributing to boiling your water.

Enno — but as others have pointed out there are transmission losses for any electricity you use, so the gas stove is probably the more environmentally friendly option, especially in Victoria with our filthy power generation. Tony Morton — How does a kettle thwart your attempt to boil less than half a litre? Will it actually not engage or are you just talking about the water metre on the side? Robert — That video is fantastic. Julian — Underfilling can damage the kettle, and overfilling can have messy consequences: I have experience of both.

If my mathematics are correct that means I am pulling 15KW thru a 16 amp breaker without it tripping.??? The power is determined by the heating element. The higher the power of a kettle, the faster it will boil a given mass of water.

Adrian, yes — but the point of the post was that only putting in as much water as you need means the kettle is running for less time. No one has said which uses the less power to boil a litre of water, an electric kettle or a stove top kettle on an electric stove which is what I would like to know. Start by just thinking about the water itself. It clearly takes the same amount of energy to boil a given quantity of water in the electric kettle and in the stove top kettle. So you can ignore this energy in doing the comparison.

For the electric kettle, the element will heat up, the body of the kettle will heat up, and there will be a bit of radiation from the kettle. For the stove top kettle, it is necessary to heat up a larger element.

The energy usage calculator for electric kettle gives you the total e nergy consumed by them. Also, you can find how much power do es your electric kettle consume. The average cost per unit charged by the electric utility. Every country has different tariff rates. The number of units of electricity consumed by the load every day considering the entered operation hours. The electricity usage depends on the wattage, number of hours of usage.

That might be a nice comparison. A watt microwave vs. The microwave might be a tiny bit more efficient since the kettle would retain some of the heat after the water is poured out. But to measure that difference would require many cups of coffee. Originally Posted by Brian B-P.
