The heating season in the north has come one after another. Recently, an article entitled "Gently warming, bringing you warmth while slowly killing your children" has been widely circulated in the WeChat circle of friends. There are six major hazards to human health caused by floor heating, and there are even risks of carcinogenicity, which has worried many consumers who use floor heating. The reporter interviewed relevant industry insiders, and they reminded consumers that they do not have to panic. The six major hazards are listed in the text. The six major hazards listed in the above article include: it is very likely to cause one of the causes of leukemia in children; it can induce cancer and accelerate the proliferation of human cancer cells; affect the human reproductive system, mainly because the quality of men's sperm is reduced, pregnant women occur Spontaneous abortion and fetal malformations; can lead to mental impairment in children; affect the human cardiovascular system, leading to decreased immune function; may have adverse effects on the human visual system. At the same time, the article also analyzed these hazards one by one. For example, regarding the possible harm to children with leukemia, the article analyzes: “Children who are in the geothermal heating radiation environment for a long time will cause changes in blood, lymph and cell protoplasm. Italian experts have studied and said that there are more than 400 people in Italy every year. Children suffer from leukemia, mainly because they live in geothermal heating and are exposed to severe heating radiation." Industry insiders deny that there is radiation in the ground Regarding the problem that floor heating radiation may cause cancer, Wang Fenglin, a senior engineer of a certain warming brand, explained from the perspective of radiation principle: "There are three forms of heat transfer, namely conduction, convection and radiation. Sunlight is the most typical radiant heat transfer, and the floor heating is also It belongs to the radiant heat transfer, so it is not carcinogenic.†Wang Fenglin said that the current ordinary household installation is water heating, that is, the natural gas is burned by the wall-burning furnace to heat the water, and then the heat is cooled by the water pipe laid in the room, thereby increasing the indoor temperature. The ordinary hot water flows in the water heating pipe, which does not generate radiation at all. In addition, regarding the social circulation of “floor heating pipeline materials will release toxic gasesâ€, the industry said that the floor heating pipes are made of high temperature resistant materials, and the water temperature usually does not exceed 60 degrees, such temperatures will not release them. Toxic gases. In addition, although part of the warm material is a polystyrene insulation board, it is also possible to release harmful substances at high temperatures, and the water temperature of 60 degrees is not in the high temperature range. Formaldehyde is not fully released because of floor heating In response to the hazard of floor heating, there is also a saying in the society that because the wood floor contains formaldehyde, under the heat of the floor heating, formaldehyde will be doubled, resulting in excessive formaldehyde content in the room. Some insiders believe that this argument has some truth. If the owner of the laminate flooring adopts the floor heating, it will easily lead to double the release of formaldehyde. This is also the reason why the industry recommends that consumers decorate new houses in the summer. Because of the high temperature in summer, it is beneficial to volatile gases in building materials such as paints and coatings. However, consumers do not have to worry too much. Opening a house with a floor heating is equivalent to forcing out the toxic gases in the room, but it accelerates the volatilization rate of harmful substances such as formaldehyde and helium. After a period of time, the remaining toxic substances in the floor are less. It is important to know that the actual operating temperature of the floor heating system is usually around 25 degrees Celsius, which is much lower than the temperature in the summer season. That is to say, even if the floor heating is not installed, the newly renovated house will continuously release harmful gases such as formaldehyde. Therefore, the responsibility for releasing formaldehyde cannot be fully promoted to the ground heating. The industry also reminded consumers that even in the winter, they should open the window and ventilate the air to facilitate the discharge of toxic gases in the house. Yue Gangju
