Japan and China are at about the same latitude, and our temperatures are not much different, so in order to survive the cold winter in the northern part of our country, we will use various methods to heat and maintain a pleasant indoor temperature.
In recent years, under the various policies of coal-to-electricity and coal-to-gas, the north of our country has officially entered the era of central heating, after central heating, the temperature of various regions in winter has been guaranteed, while our neighbor Japan has adopted a completely different heating method from ours.
China has a large land area, the temperature difference between the south and the north is huge at the same time, the north has always had the demand for heating because of the long winter, and the south because of the short winter time, heating facilities can not be sold in the south, so there is no habit of burning heating.
Japan has similarities with our country in this respect, some places are very cold, it can reach more than minus 30 degrees, and some places have perennial summers, such as Okinawa, like in Okinawa, there is no need to prepare things for winter, because there is no winter.
Excluding this perennially hot area, only 10% of Japanese people can reach more than minus 30 degrees Celsius in winter, and most Japanese people do not live in this particularly cold area, and 80% of them are concentrated in cities.
Therefore, in order to cope with the different heating needs of different regions, the heating methods adopted by residents in various places are also diverse, each with its own characteristics. Basically, from urban to rural, from rich to poor, the way of heating is different.
Japan is a populous country, with 378,000 square kilometers to live inWith a population of 2.5 billion, the amount of land that can be harvested per capita is very small, and the most common in Japan are single apartments and offcuts houses of various shapes.
For example, near the three-way intersection, there is a triangular protrusion, and the Japanese who are good at using the land find that this small triangle can also be inhabited, so they build houses in this area, which has also become a Japanese characteristic.
There are very few houses of more than 100 square meters in Japan, and most of them are about 60 or 70 square meters. Most of the leftover houses are only twenty or thirty square meters, and sometimes there are several people living in such a small place, which is very crowded, and heating has become a big problem for them.
In Japan's bustling cities, high-rise buildings are basically heated by electricity, and most of the bustling cities only need air conditioning to meet heating needs in winter, but Japan's electricity bill is very expensive, about 1 yuan per kilowatt-hour of electricity.
According to the demand of winter, the air conditioner is turned on for a long time every day for several months, which is the heating method of many middle-income groups in Japan, but there are not only rich people in the city, but also a large number of poor people.
The poor in the city have a variety of ways to heat themselves, including those who burn gas, those who burn wall-hung stoves, and those who provide underfloor heating in various ways, which add up to enough for them in the city to survive the winter.
In Japan, it is very common to go to the gas station with a large box to buy diesel or natural gas, and in order to save money, you will use natural gas for heating, and go to the gas station every once in a while to fill up 500 liters of diesel, which can be used for about ten days.
This method is much cheaper than heating with electricity, but the safety hazards are also more prominent, and there has been a period of time when diesel and gas were used for heating in China, and cases of carbon monoxide poisoning caused in this process are not uncommon.
It is precisely because of the great potential safety hazards of this heating method that China has begun to adopt the method of central heating to reduce the occurrence of residents who are poisoned by heating and endanger themselves and their families because of a lack of safety knowledge.
The problem of gas heating is easy to poison is also prominent in Japan, and there is even a traditional way of suicide in Japan, which is carbon monoxide poisoning.
However, this is already the most economical way to heat the house in Japan, and the most common thing in the winter in Japan is that many families take a pipe and put a gas tank outside the house to prevent gas poisoning in order to prevent carbon monoxide poisoning.
Seeing this, everyone will definitely have a question, why doesn't Japan adopt central heating for heating? We are different from Western countries, there is a gap between the vast land and the sparsely populated area and our actual national conditions, and the advantages of using central heating for a concentrated population outweigh the disadvantages.
In fact, in Japan, the policy of central heating has been adopted for a period of time, but this policy has not been implemented for long, and Japan has ushered in a **, which is commonplace for the Japanese.
But this ** has caused very serious consequences, Japan's underground central heating pipes are all cracked, collapsing out of the ground, causing major safety hazards, so far Japan has never thought about central heating.
In addition to the most simple and crude reason for not being able to centrally heat, another reason why Japan cannot have central heating is that Japan is really good at using limited space, building houses at three-way intersections and building houses in the corners of residential buildings.
Central heating requires the laying of pipes, which requires that the place where we live is relatively regular, so that the pipes can be laid there. It is also difficult to achieve a residential model in Japan, where there is a small place in the east and a small place in the west.
