Is it worth it? Is it worth paddling? Is it necessary?
I. Winter environment in North and South China
Outdoor in the north: the winter is long, the temperature is very low, there will be heavy snow but the air is dry.
Indoor in the north: as long as there are heating facilities such as floor heating, shops, supermarkets and schools are perfect; Some rooms can even wear only short sleeves.
Outdoor in the south: winter is short, the air is wet and cold, the temperature is not as low as that in the north, but it is biting cold.
South Indoor: Because there is no heating, the indoor and outdoor temperatures are the same (even colder). It seems that the temperature is not low, but it will make people feel wet and cold from the inside out.
Summary: there are perfect heating facilities in the north, so it is warm as long as you don't go out, and the cold wind blowing outside will make people feel cold; In the south, because there is no heating equipment and the air is humid, people will always feel the cold seeping into the bone marrow, so the winter in the south is actually not warmer than that in the north.
Two. ? Heating demand in southern China
I believe many people think that there is no demand for heating in the south, because there is no heavy snow all winter like in the north, and there is no central heating. They subconsciously feel that the cold in the south can "endure" the past. Indeed, the temperature in the south is not as low as that in the north, and the heating time is shorter than that in the north, but it is generally humid in the south, which will cause the temperature actually felt by the human body to be lower than the displayed temperature, bringing a cold feeling from the inside out, which is why most northerners find the winter in the south more difficult. In addition, humidity and cold will increase the sensitivity of joint nerves and damage the joint health of the body, so it is necessary to keep warm in the south.
Three. ? Heating mode suitable for the south
At present, the most common heating mode in South China should be air conditioning heating. Because of the existence of air conditioning refrigeration and heating, for most southerners, it saves a heating cost. However, there are many problems in the use of air conditioning heating. The first is the poor experience. Air conditioning belongs to thermal convection heating, which drives the hot air circulation of the whole room by heating the air above. Because it keeps blowing hot air on the head, it will make people dizzy and hot. Moreover, there will be obvious dust and noise during the heating process, so it is even more uncomfortable for people with rhinitis or poor sleep. Secondly, air-conditioning heating actually consumes a lot of electricity, because air-conditioning can not achieve high electrothermal conversion, so from the perspective of energy saving, air-conditioning heating is not ideal.
Floor heating takes the whole floor as the radiator, and the whole floor is heated evenly by different heat media to achieve the purpose of heating. It is far superior to air conditioning in comfort, but in energy saving, the floor heating effect of different heat sources is different, but it is superior to air conditioning on the whole. Therefore, if conditions permit, it is best to choose floor heating as much as possible.
Four. ? Misunderstanding of floor heating in South China
The popularity of floor heating in the south is far less than that in the north, mainly due to the lack of understanding of floor heating in the south and some stereotypes: "Floor heating is expensive and can't be installed", "It's not safe to use", "It's too stuffy and uncomfortable to use" and "It's too troublesome to maintain every year" (please discuss these issues together) ... But it doesn't mean that people in the south can't accept floor heating. The understanding of floor heating is incorrect. If everyone can understand that floor heating actually has a good heating effect and cost performance, who wants to tremble in winter? ...
Five, the cost of using floor heating in the south.
Different from the way of central heating in the north, the floor heating in the south can only be installed by itself, which will involve an initial installation fee, but the floor heating will not be too expensive. According to their own heating needs and the warm-keeping effect of the house, it can be installed from a few K to 20,000 to 30,000, which is similar to air conditioning. Secondly, the late use fee is charged by area in the north, whether it is used or not, while the south can provide intermittent heating according to its own needs. Therefore, it is suggested that when choosing floor heating, it is best to consider having an intelligent temperature control system with fast heating speed, so that it can be used as needed, and the temperature can be controlled in different rooms, which will save a lot of use costs.
Finally, we return to the question of whether the floor heating value in the south is worth it. In terms of demand, the south is not warmer than the north. Compared with the experience of "surviving the whole winter" every year, it is more wise to choose a durable and reliable floor heating. From the cost point of view: under normal circumstances, a suite only needs to install floor heating once. After developing good habits of use and maintenance, the floor heating has a high cost performance, and there will be no "affordable situation". So it is necessary to install floor heating in the south ~
