How much is a ton of coal for heating?

Now that the weather is cold, heating work has started everywhere, so which is better for indoor decoration heating, floor heating or hanging board? If it is used for heating, how much is a ton of coal? Many friends want to know the answer to this question. Let's have a quick look.

Is floor heating better or hanging film better?

1, installation effect

All coils or heating cables of floor heating are buried under the floor, which saves space and is beautiful. Laying floor heating is generally planned and installed before the renovation of new houses. Unless the old house is transformed as a whole, it will do great damage to the overall decoration. The installation of radiators is also very versatile, especially the damaged area of old houses is not large, and there are many types and patterns of radiators, which are beautiful and generous.

2. Installation conditions

Floor heating or radiator for decoration depends on your heating conditions. If it is central heating, only radiators can be used for heating. Central heating belongs to high temperature and high pressure heating, and geothermal heating belongs to low temperature and low pressure heating. You can also use a decompression pump to decompress, and you can also use floor heating. However, if the decompression pump is broken, the heating must be stopped, otherwise the geothermal pipeline can easily bear the high pressure and leak. The purpose of these two methods is the same, but the heating methods are quite different; If it is self-heating, you can use it all, and consider which one is more suitable according to your own needs.

3. Post maintenance

Radiator and floor heating, one bright, one dark and one floor heating pipeline are all laid underground. The pipeline will produce scale after 2-4 years of operation, which needs professional equipment to clean. If there is water leakage, it is necessary to pry open the ground for maintenance, which is costly and troublesome, and its use in the bathroom is also very limited. Comparatively speaking, the advantages of radiators are obvious. At present, there are many types of radiators on the market, with large selection space, convenient maintenance and stable performance.

4, the use effect

The floor heating starts from underground, and the heating is very comfortable and the temperature is even. However, heating the ground will make dust of various weights float at a certain height from the ground, and the fiber particles that fall off when wiping the ground will also drift around, which will have a certain impact on health. Families with old people, children and respiratory diseases had better not use floor heating. The radiator radiates heat by convection through indoor air circulation, and the heating effect is relatively fast, generally about 20 minutes, and we can reach the required temperature.

How much is a ton of coal for heating?

10 10 18, residents in Inner Mongolia, Gansu and other places reported on several online platforms that the price of heating coal rose this winter, and the coal price in Gansu Province doubled year-on-year. The highest coal price in Bayannaoer City, Inner Mongolia is three times that of the same period last year.

People in the coal industry analyzed to reporter Jim that due to the shortage of coal, the domestic coal price rose overall this year, which led to an increase in the price of heating coal.

Ren Yanbo, secretary-general of china association of rural energy industry Civil Clean Stove Committee, said that the rising coal price is a national phenomenon, and there is no good solution at present. Traditional heating methods in rural areas may appear in large numbers this winter, such as burning straw and firewood.

/kloc-on the afternoon of 0/9, the national development and reform commission said it would intervene in coal prices according to law.

"I haven't seen the coal price exceed 1000 yuan for 50 years."

101October 18, residents in Inner Mongolia, Gansu and other places reported on several online platforms that the price of heating coal this winter has doubled compared with the same period of last year, causing pressure on life.

A resident living in Bayannaoer told Jim that his family just bought 4 tons of heating coal this winter, and the price was 2,000 yuan a ton. "Last year, the same coal was 800 pieces per ton, and the quality was almost 600 pieces per ton. I am 50 years old and have never seen coal prices rise to more than 654.38+10,000 yuan before. " The resident said.

The owner of a local coal station said that the price of coal was more than 800 yuan a ton in September, when the price of residential coal stations was set at one ton in 900 yuan. Since 10, the wholesale price of coal in Ordos has risen to more than 1900 yuan. "The purchase price is too high for the villagers to accept. It was not sold this month. " He said.

In addition to Bayannaoer, residents of Chifeng, Tongliao and Ordos in Inner Mongolia also reported the problem of high coal prices. The staff of a coal mine in Erdos told Jim that there are not many restrictions on heating coal, as long as the fire-proof blocks are resistant to burning. But now the cheapest ex-factory price of coal is above 1000, and the better 167.

The average family spends twice as much on coal in winter as usual.

Recently, the price of coal used in many places in Gansu is similar to that in Inner Mongolia.

Master Qiu, a taxi driver in Zhangye City, Gansu Province, told reporters that the local coal price in Zhangye has risen sharply recently, and many taxi passengers are talking about it. "After moving to the city, our family stopped burning coal, but our hometown still uses coal, and the annual consumption is about 1.5 tons. Coal burning is mainly used for heating and cooking. " Master Qiu said that his hometown needs to buy coal every year. Take the coal of the same quality purchased last year as an example. Last year, a ton was only 600 yuan, and this year it rose to 1.200 yuan. "The coal with better quality was 1 10,000 yuan a ton last year, and it needs10.8 million yuan or even higher this year." Master Qiu said.

Mr. Kang, who works in a township government in Weiyuan County, Dingxi City, Gansu Province, also feels at a loss. Recently, because many local people told him and other staff that coal prices had risen by a large margin, as a grass-roots public official, he didn't know how to respond to the people's demands. "Since August this year, coal prices have been rising, but the biggest increase is in recent times. In previous years, a catty of coal was only about 50 cents, and now a catty of coal has risen to about one dollar. " Mr. Kang said that the price of a ton of coal used to be 1000 yuan, but now the price of a ton of coal has risen to 2400 yuan.

"Generally speaking, an average family needs at least 1.5 tons of coal all winter. In the past, it only needed 1.500 yuan, but now it needs 3,600 yuan, which is really a big expense for local rural residents. " Mr. Kang said, "It's very cold here in winter. It's only 5438+1mid-October, and it has snowed three times. The temperature is below zero, and most locals rely on burning coal to keep warm. "

Since September this year, many Gansu netizens have reported the problem of rising coal prices to relevant units on the People's Daily leadership message board. One of Lanzhou netizens reported that the coal price in Lanzhou last year was per ton 1500 yuan. When the coal price was consulted at the beginning of this year 10, the price had reached 2400 yuan per ton. On June 65, 438+08+02, the coal price has risen to 2800 yuan per ton, and it is out of stock.

How many months does the heating take?

According to different regions, the time is different. The extremely cold heating time in Northeast China is long, generally from 10 to March of the following year, and the central plains time is relatively short.

There are several ways of heating.

Household heating methods include: radiator, water heating/electric floor heating, air conditioning, electric oil stove.

First, the radiator

Generally, radiators are generally installed in collective heating in the north, and self-heating households need to install wall-hung boilers for heating at the same time.

Advantages: the installation cost of the whole system is relatively low, the heating installation is fast and convenient, and both old houses and new houses can be installed and used. The heating effect is more comfortable, the heat dissipates quickly, the warmth can be enjoyed in time, and the later maintenance cost is extremely low.

Disadvantages: it will occupy the beautiful wall of the home.

Second, the circulatory system.

It is the most popular floor heating in recent two years. It is laid underground, so it is only suitable for installation and use in new houses without decoration.

Benefits: The water temperature is lower than that of the radiator, but the heat dissipation area is large, which makes the body feel more uniform, and the heat is stored for a long time and lost slowly. Heating is efficient and economical, the longer it is turned on, the more energy-saving it is, and it is more suitable for heating all day for a long time.

Disadvantages: First of all, the system laid and installed is the most expensive, and the installation, renovation and maintenance projects are complicated, with high technical requirements and high maintenance costs. On the other hand, the heating rate of floor heating is the slowest, and it takes more than ten hours to heat up.

Third, electric floor heating.

In fact, the principle is the same as that of the circulation system, except that it is powered on.

Benefits: The installation cost is higher than that of radiator, but it is more economical than the circulating system. The heat dissipation operation is efficient and fast, and it can dissipate heat quickly.

Disadvantages: the use of electric floor heating is quite power-consuming, and it does not have good thermal insulation performance, and it is basically cold when power is cut off. In terms of health, electromagnetic radiation has certain hidden dangers and needs special attention.

Fourth, air conditioning.

Benefits: You can enjoy cold and warm use for thousands of dollars, and it is convenient to use without installing other equipment.

Disadvantages: the comfort of heating is greatly reduced. For areas below 0 degrees, the power consumption is serious and it is easy to trip.

Fifth, electric heaters such as electric oil heaters.

Advantages: cheap, compact and easy to move.

Disadvantages: high energy consumption, poor power consumption and comfort, only local heating.
