Which is more economical, gas boiling water or electric kettle boiling water?

Taking boiling water as an example, the heat generated by primary electricity is about 850 kcal, and the efficiency of electric kettle is 80%, so the effective power generated by primary electricity is 680 kcal. If you want to boil 425 calories of water, you need 425÷680=0.625 kWh. According to the electricity 0.5 yuan calculation, the electricity charge for a pot of 5L water is 0.5*0.625=0.3 12 yuan.

The heat of 1 m3 natural gas is about 8400 calories, while the thermal efficiency of gas stoves is usually only 50%, so the effective power in a m3 natural gas is only 4200 calories. According to the calculation of 2.26 yuan per cubic meter of natural gas, if you want to boil 425 kcal of water, you need 425÷4200*2.26=0.228 yuan.

Matters needing attention

However, it should be noted that the electric kettle will automatically turn off the power supply and stop consuming energy after boiling water. However, when using natural gas, you need to be vigilant at all times. If you don't pay attention, even if the fire is turned off after the water is boiled, it will continue to consume energy.

Moreover, if the water is too full, it may overflow to put out the fire, or even dry boil the kettle, which will bring more security risks in short.
