Boiling a kettle is generally cheaper than boiling a pan due to the fact that kettles are designed to be more energy efficient and boil water faster.
Comprehensive answer to the question
Boiling a kettle is generally cheaper than boiling a pan due to the fact that kettles are designed to be more energy efficient and boil water faster. According to the UK’s Energy Saving Trust, boiling a kettle only uses about one-third of the energy it takes to boil water on a stove.
“Boiling water in a kettle is more efficient than heating it on the stove,” says Julian Kirby, a campaigner at Friends of the Earth. “The kettle is better insulated than a pan, and so loses less heat to the air while it boils.”
Here are some interesting facts about the energy efficiency of boiling water in a kettle versus a pan:
A kettle that is filled to the minimum level and boiled once a day uses less energy over a year than a 100-watt light bulb does in just six hours.
A gas stove uses more energy than an electric stove to boil water in a pan due to lower efficiency.
Induction stoves are the most efficient way to boil water in a pan, using up to 90% of the energy produced versus only 40% for gas stoves.
A slow cooker uses significantly less energy than both a kettle and a pan, but it takes a much longer time to heat water.
To compare the energy efficiency of boiling water in a kettle versus a pan, here is a table that shows the average energy consumption for each appliance:
Appliance
Average energy consumption
Electric kettle
0.1 kWh per boil
Gas stove
0.3 kWh per boil
Electric stove
0.15 kWh per boil
In conclusion, if you want to save energy and money, it’s better to boil water in a kettle rather than a pan. However, if you have an induction stove, boiling water in a pan can be almost as efficient as boiling it in a kettle.

The cost of boiling a kettle in the UK based on the current energy price cap of around 30p per kilowatt hour is just under 2p for two cups, just over 3p for four cups, and just under 5p for six cups, according to a YouTube video experiment. However, the price cap is expected to rise to around 50p per kilowatt hour in October and could rise further in the spring, which would result in an annual cost of around £30 for 500ml, £60 for 1 liter, and just under £90 for 1500ml of boiling water. Despite the relatively low cost, the creator cautions against overfilling the kettle to avoid wasting energy and money.
Although kettles use less energy overall, the differing prices of electricity and gas meant the hob worked out cheaper. "If you’re looking for an energy saving, go for the electric kettle," he said.
Using a kettle to boil water instead of a pan on an electric stovetop is more efficient than boiling water in a pan because of the lower heat transfer rate. Consider how much time it takes for your water to come to a full boil and how long it takes to cool down after being heated.
Gas hobs are about 40% efficient- but that’s if the kettle is much wider than the burner. Whereas an electric kettle is about 80% efficient- and MUCH faster, and switches itself off automatically, so is more convenient.
But the cost of the electricity per kWh is usually much higher than gas. Relatively speaking if your gas is more than 50% of the cost of electricity per kWh of energy then it’s cheaper to use electricity. Still, most people don’t boil a whole bunch of water, and a penny either way is usually negligible, so you should usually go with whichever is more convenient.

Is it cheaper to boil a pan of water than a kettle?
IT TAKES the same amount of energy to heat one litre of water no matter which method of heating used. The only difference in the methods is the amount of time each takes.

Is it cheaper to boil a kettle or a pan on gas?
Because gas is cheaper than electricity, it works out slightly cheaper to boil water on a gas hob than using an electric kettle, as long as you are boiling just the quantity you need and switch off the hob as soon as it has boiled.
What is the cheapest way to boil water?
Low minimum fill – It’s always cheaper to boil less water, so kettles with a lower minimum marker will save you money if you’re heating water for just one cuppa.
What is the most energy-efficient way to boil water?
Response to this: Answer: The electric kettle won hands down. The real advantage with the kettle is on the first cup. It boils in half the time as the first cup boiled in either the microwave or the stove. Since (at 1450 Watts) it uses about the same amount of power as the others, halving the time halves the energy.
Is it cheaper to boil water in a kettle or gas?
In reply to that: Only fill and boil the kettle with as much water as you need. … Because gas is cheaper than electricity, it works out slightly cheaper to boil water on a gas hob than using an electric kettle, as long as you are boiling just the quantity you need and switch off the hob as soon as it has boiled. Is it better to boil water in a pan or kettle?
Is an electric kettle worth it?
Response to this: Electric kettles are more expensive than your standard stovetop kettle, but they have many advantages that make them worth the extra cost. For example, you can boil water much more quickly and without effort on your part with an electric kettle. In addition, electric kettles also come with safety features.
Should I Refil my kettle after boiling?
Answer will be: After boiling the kettle and using the hot water, refil the kettle from the tap and the cold water will absorb the heat in the kettle so as to boil quicker next time,this could save you up to £1 a year (at least)! Political?….I dont do Political….well,not much!
Is a full kettle more expensive than a half-full?
‘NNaturally, it is more expensive to boil a full kettle than a half-full kettle, as there is less water that needs to be heated, meaning less energy is used. This is why it is so important not to overfill your kettle and only fill it with the amount of water you need.’
