The gas stove and water heater with electric kettle, boil water which is more economical
Cheap electricityThe following is a detailed calculationIs it cheaper to convert into a unified unit? Change to international units belowKilowatt hour, that is, 1 kwh =3600000 Joule, then 1 joule electricity price =0.5/3600000=1.39e-7 yuanOne kilogram of liquefied gas 12 million calories, net weight is 15 kilograms a container of gas (standard household tank) 90 yuan and above, as for international units of joules. A Joule gas price is 1.19e-7 yuan.From the above calculation, you can see that electricity is about 14%. more expensive than gasBut we also consider the problem with water heater thermal efficiency, basically no heat loss, electric energy into basically are absorbed by water, no waste. The thermal efficiency of nearly 100%. even 95%.
Comparison of electric water heater, two with you for speaking, to see his power, fast heat minimum is eight hundred watts relative you said electric kettle, electric kettle should be between three hundred to five hundred, electric kettle more money if I compared with the hot pot or electricity appliances, household appliances I heat a five liter power of eight hundred to fifteen points, is boiling water.
Gas to do water than cooking costs gas, according to your electricity bill, one yuan a kilowatt hour (hour kilowatt), the general electric kettle is 1500 watts -2000 watts. That is to say, once electric energy can boil 5-6 pots of boiled water. If you press the gas calculation, a gas is definitely higher than the price of a kilowatt hour, and will never be more than the electric kettle boil water. Electricity is still cost-effective.
