Which has lower operating costs, an electric heating boiler or a natural gas heating boiler?

It is necessary to calculate based on the heat load, as well as the construction and operating costs of different heating methods. If the factory has its own power supply with excess electricity, the cost of electricity will definitely be low. If it’s a natural gas transmission station, using natural gas costs nothing, so of course natural gas is cheaper. Use your own brain to think about things like this.

What is the difference when calculating based on a price of 4 yuan per cubic meter for piped natural gas and 5.49 yuan per kilowatt-hour for electricity? It would be useful to **know the energy losses of gas water heaters and electric water heaters; 1 cubic meter of natural gas can produce 35,500 KJ of heat. How many kilojoules of heat are generated per unit of electrical energy? 3600 KJ of heat. The cost per MJ of heat from natural gas = 4/35.5 = 0.1127 yuan. Cost of electricity per MJ of heat = 0.549/3.6 = 0.15 yuan. The efficiency of gas stoves is around 80%, while that of electric stoves is about 95% or even higher. Gas cost: 0.1127/0.8 = 0.146 yuan (there are also auxiliary devices that require electricity, which increases maintenance costs as well as the costs related to waste treatment facilities). Electricity cost: 0.15/0.95 = 0.158 yuan
