Which is more economical: heating water with electricity or natural gas?

Introduction Which is more economical: heating water with electricity or natural gas? When using natural gas, 80 calories equals 80 kcal. The main component of natural gas is methane. Its density is 55% of that of air and it is easy to volatile.

Which is more economical: heating water with electricity or natural gas?

When using natural gas, 80 kcal corresponds to 80 kcal. The main component of natural gas is methane. Its density is 55% of that of air. The calorific value of one cubic meter is 8,500 kcal. /p>

The rise of the water requires 80/8,500 cubic meters of natural gas, or 0.0094 cubic meters. The approximate price of one cubic meter is 2.2 yuan. A liter of natural gas boiled with water costs 0.02 yuan.

When using electricity, the calorific value of each kilowatt hour of electricity is 860 kcal, that is, a liter of water requires 80/860 kilowatt hours of electricity, or 0.093 kilowatt hours of electricity. an hour of electricity costs 0.55 yuan. One liter of electricity is used to boil water. Opened at 0.05 yuan.

After calculation, using natural gas to boil water saves more energy and money.
