Winter in the south is cold and humid. Why doesn't anyone install heating indoors?

As far as I know, some newly-built buildings in some areas in the south have begun to use heating, but in my opinion, it is a pure waste of resources. I think those developers who install heating in the south just want to raise housing prices. Why do you say that? Because I don't think it is necessary to install heating in the south. Heating in the north, because of the climate, the weather is really too cold, MINUS 3 or 4 degrees, without heating, you will definitely freeze into a cold dog. Moreover, the winter in the north lasts for a long time, and almost the whole winter is covered by universities. Even without heating, other heating facilities are needed. For example, rural areas all live in kang.

Although the weather in the south is cold, wet and cold in winter, the winter time in the south is short, and the cold and wet weather lasts for a short time. In the south, there is usually extremely cold weather during the winter solstice, and it usually lasts for one or two days. Generally, the extremely cold climate will appear when it rains and snows in winter in the south, while the whole winter in the north begins in mid-October and lasts until March of the following year, which is basically covered with snow. Heating in the north is necessary for the environment, and it is too wasteful for the south to install heating for those days or 2 days. An air conditioner can solve the problem of cold in winter and hot in summer, so it is not worth heating.

In addition, heating is generally coal-fired. If heating is widely used in the south, it will inevitably cause more serious environmental pollution. Now the severity of smog in China is a disastrous problem. If the whole country uses heating and burns coal, the air will deteriorate and the energy will be greatly reduced.

A lot of manpower and material resources are also needed to install the heating system. Before using the heating system, it is necessary to test whether the heating system is faulty or not, and the heating system needs regular maintenance to avoid water leakage. Besides, the south itself is a humid climate, and the installation of heating will definitely consume a lot of heating. Radiators rust and rot easily. Moreover, the arrival time of the cold wave in the south is not fixed, so it is necessary to install heating in December or January. It's also a problem. There can't be a fixed heating time at all. And even if there is heating, do you need heating in sunny days? How to charge the heating fee is also a problem when heating is not provided for one day. Besides, in some southern areas, it is particularly cold only when the cold wave strikes every year. In order to get through the cold in those days, it is necessary to install a central heater, which takes up space and wastes the manpower for maintenance. It is not worth the loss. Not as good as an air conditioner. If there was no cold wave that year, it would be a warm winter, not to mention the need for heating. So to sum up, I don't think it is necessary to install heating in the south.
