Which is cheaper to boil the same weight of water with gas or electricity?

<> many families generally have two options when cooking and boiling water, using natural gas or electricity, so which is more economical to burn the same weight of water, natural gas or electricity?

If the efficiency is 100%, the electricity is about 2 times the cost of using natural gas, unless the efficiency of using natural gas is less than 1 2 of the electric kettle, but the efficiency of the natural gas stove is generally 55%, and the efficiency of the electric kettle cannot be 110%.

Although no one cares too much about the cost of boiling water, we can do a simple calculation, because the result is likely to be different from what everyone thinks! Thermal efficiency of boiling water in household gas stoves.

It is about 30%-40% lower (because a large part of the heat from the gas stove is dissipated into the air), and 35% for the time being. The thermal efficiency of electric kettles is relatively high, up to 85%.

Purely from the calorific value.

In comparison, 1 kWh of electricity 1 kilowatt-hour (kw road h) = joules.

j) kcal kcal. The calorific value of one cubic meter of natural gas is 8,000 kcal to 8,500 kcal (8,250 here), and the calorific value of one cubic meter of natural gas is times the heating value of one kilowatt-hour.

Burning the same volume of water in two ways requires receiving the same amount of heat, if the thermal efficiency is counted, thenEvery cubic meter of water boiled by natural gas is equivalent to water boiled by electricity.

Thermal efficiency, although theoretical, is often not as accurate as experiments

Electricity: It takes 9 minutes and 34 seconds to boil water, and the rated power of the electric kettle.

It is 1500w, and the electricity price is considered yuan kilowatt hour.

Then the cost = yuan.

With natural gas: boil liter water, gas meter.

From the point of going, ** calculate the yuan cubic meter, then the cost = (yuan.

If the cost of using natural gas is converted into the same liter of water as boiling electricity, the cost is yuan.

Experiments have shown that by boiling the same weight of water, natural gas is cheaper than electricity.

I think it's cheaper to boil water with electricity, and it's more convenient to use, and the main thing is that the water tastes clearer.

First of all, let's understand the unit conversion, 1 kilowatt-hour of electricity 1 kilowatt-hour (kw road h), the calorific value of a cubic meter of natural gas is 8000 kcal to 8500 kcal (8250 here), plus the country's charging standards for electricity and natural gas are different, it is cheaper to burn natural gas at present.

Natural gas has won the favor of everyone with its large firepower and cheapness, and natural gas has become an important part of family life with its unique advantages.

In real life, boiling 1kg of water with natural gas and electricity, do you know which is cheaper?

Boil water, of course, is more cost-effective to use electricity. This kind of boiled water does not require much electricity, but you can drink very good boiled water, which is very good.

Personally, I think electricity is more cost-effective, and it is also very convenient. That's why I usually use electricity to boil water.

Which is more economical to boil water with electricity or natural gas?

It will be more convenient to boil water with electricity, and you don't have to worry about it with one button to turn it on, which is more convenient, and the electric kettle is also cleaner, because when using a gas stove to boil water, it is inevitable that there will be fumes in the kitchen.

Natural gas is cheap, take 5 liters of water as a calculation, which means that the water has to be burned from 0 degrees Celsius to 100 degrees Celsius. From this, it is calculated that the heat required to boil the water is 500 kcal.

The ** of natural gas is 3 yuan per cubic meter, we need 500 kcal, then divide by 36,000, and then multiply, the result is that it is the natural gas that needs to be consumed to boil 5 liters of hot water. Then we multiply the **3 of the natural gas by the equal yuan.

One kilowatt-hour of electricity is about equal to 3600 kilojoules, then the electricity fee is taken per kilowatt-hour, if you need to heat 5 liters of water, then the degree required is about equal to the degree, we use the kilowatt-hour multiplied by 6 cents per kilowatt-hour, calculated to be about yuan, which is the cost we need to consume to boil 5 liters of hot water with electricity.

Natural gas is cheap.

Natural gas is cheap, so if you take 5 liters of water, it means that the water has to be heated from 0 to 100 degrees Celsius. From this, it is calculated that the amount of heat required to boil water is 500 kcal.

It will be more convenient to boil water with electricity, the basic key to open does not need to be tubed, saving more trouble, in addition to the electric kettle is also clean, because when using a gas stove to boil water, there will be oil smoke and other conditions in the kitchen.

The ** of natural gas is 3 yuan per cubic meter, which requires 500 kcal, then divided by 36000 and multiplied by 0 9, the result is 0 0125, that is, 5 liters of hot water need to consume 0 0125 natural gas. Then multiply the **3 of natural gas by the equal yuan.

One kilowatt-hour of electricity is approximately equal to 3600 kilojoules, so the electricity bill is 0 6 yuan per kilowatt-hour. If 5 liters of water need to be heated, the kilowatt-hours required are approximately equal to kilowatt-hours. Then multiply 0 13 kWh of electricity by 60 cents per kWh, which is about 0 078 yuan, which is the cost of boiling 5 liters of hot water.
