Relatively speaking, natural gas is more cost-effective;
The analysis is as follows:
Air conditioning:
Advantages: easy operation, fast heating, and Temperature control
Disadvantages: Dry air, noisy
Do the math: Starting from July 1, 2012, our city will fully implement the tiered electricity price policy for residents. Monthly electricity consumption is divided into three levels. After comprehensive investigation of the actual situation, we use about 0.6 yuan per kilowatt hour (including stepped electricity prices).
Take a 1.5P air conditioner as an example. It runs for 5 hours from 18:00 to 23:00 every day, and consumes 1.2 degrees of electricity per hour and 6 degrees of electricity per day. Calculated based on the electricity cost of 0.6 yuan per kilowatt hour, the cost of a heating season from November to March (120 days) is: 0.6×6×120=432 yuan.
Electric heater:
Advantages: rapid local heating, small size, movable, no noise
Disadvantages: small heating area
Do the math: Many office workers will have a small electric heater under their desk. Its convenient mobility also makes many families choose it for heating. The power of these electric heaters sold in many stores generally ranges from 500 watts to 2000 watts. If it is a 1500-watt electric heater, running for 5 hours from 18:00 to 23:00 every day, it consumes 1.5 degrees of electricity per hour and 7.5 degrees of electricity per day. Calculated based on the electricity cost of 0.6 yuan per kilowatt hour, the cost of a heating season (120 days) is: 0.6×7.5×120=540 yuan.
Natural gas
Advantages: The heating area is larger than that of electric heaters
Disadvantages: Be careful not to get burned
Do the math: Do this every day When used for 5 hours from 18:00 to 23:00, the gas consumption reaches up to 2 cubic meters. Calculated based on the residential gas price of 1.86 yuan/cubic meter, the cost of a heating season (120 days) is: 1.86×2×120=446.4 yuan.
Floor heating:
Advantages: Even indoor heat dissipation and comfortable to use
Disadvantages: Expensive installation cost and high natural gas consumption
Do the math: Utilize Water floor heating is a heating method that uses natural gas to heat water to a certain temperature, transports it to the water pipe cooling network under the floor, and achieves heating purposes through floor heating.
Water floor heating is not very common in residents’ homes. The reporter interviewed a Mr. Yang. The area of ??his house is 98 square meters. I started using floor heating in 2011. The installation fee is 100 yuan/square meter, and the total cost is about 10,000 yuan. "The first day after the floor heating was installed and turned on, it consumed almost 50 cubic meters of natural gas, because it took almost a day to heat the entire house, so I bought another 100 cubic meters of natural gas the next day." Mr. Yang said , last winter, his home heating was turned on from the end of December to February this year, and the total cost of natural gas was about 1,000 yuan. In addition, floor heating cannot be turned off at any time like other heating equipment. It should be kept on most of the time, so that the temperature will be maintained at a constant temperature of more than 20 degrees. Otherwise, turning it off and turning it on again will consume more natural gas to reheat the floor heating. .
Conclusion:
Compared with electricity and natural gas, using air conditioning to heat 1 kilowatt hour of electricity can produce about 800 calories of heat, and the cost is about 0.6 yuan. Using natural gas heaters and floor heating for heating, 1 cubic meter of natural gas can produce 8,500 kcal of heat and costs 1.86 yuan. Then one cubic meter of natural gas is equivalent to 8500÷800=10.625 (kWh) electricity. The electricity bill for using air conditioning to generate 8500 kcal of heat is 10.625×0.6=6.375 yuan, which is 6.375÷1.86=3.43 times that of using gas for heating.
In addition, if an electric heater converts all electrical energy, it can produce up to 860 calories of heat, which is not much different from the heat generated by an air conditioner.
According to the reporter's survey, compared with the above four heating methods, using natural gas stoves should be considered the most cost-effective in terms of the heat generated and the corresponding price. In addition, winter is a peak period for residents’ electricity and gas consumption, and the amount of electricity and gas consumption must also be determined according to specific conditions.
Tips for safe use of electricity and gas:
When purchasing air conditioners, consumers should purchase based on power and check whether the power supply of the house is stable, otherwise the circuit will be burned out.
When purchasing electric heaters, consumers should choose good quality brands, read the trademark, manufacturer, and product certificate clearly to avoid buying "three no's" products. They must stay away from flammable items when using them and turn off the power when leaving.
When using floor heating or natural gas stoves, be sure to prevent water leakage, keep indoor air flowing, and prevent carbon monoxide poisoning. Before leaving, be sure to close the natural gas main valve.
