current heating season coincided with the northern region, "the human body to warm the six hazards" and other articles and spread in the micro channel circle of friends, where warm carcinogenic, harmful theory has been circulating on the Internet for many years, we had confirmation.

[1] warm radiation hazardous to human right?

Plumbing Heating is like using a hot water bottle, electric heater heating the magnetic field is very weak, far less than the extent of the disease caused by the human body.

It is understood that warm is called 'radiant floor heating ", the two types of electric heating and plumbing, plumbing currently on the market are mostly used. Plumbing is 35 ℃ -50 ℃ hot water (up to not more than 60 ℃) through the heating pipe laying, hot water through the pipe wall and the multilayer mat material on which to lay the indoor environment heat heating system. Electric heating cables buried in the ground, the equivalent electric blankets, heating current through the heating.

Nanjing company salesman introduced a number of heating, plumbing, heating of water, like using hot water bottle as not harmful.

net posts, said the warm likely to cause childhood leukemia to induce cancer and accelerate the proliferation of cancer cells, affect the reproductive system, leading to mentally challenged children, affect cardiovascular system, causing decreased vision and cataracts, among many reference to the term "heat radiation."

Tsinghua University Associate Professor Wang Baolong Building Technology Division noted, to warm the reason why there is "radiation" is the wording appears to emphasize its main mode of heat transfer is "radiation heat transfer", and the everyday concerns of radiation is not the same of.

Tianjin Office of heating engineer heating Management Office, said Li Wei, heat transfer in three ways: namely, heat conduction, convection and radiation. thermal radiation is a very common natural phenomena, including cooling the body temperature of heat by radiation is home to warm the thermal radiation is harmless.

Professor of Urban Construction and Safety Engineering, Nanjing University, Chen Liping introduction, the temperature difference between the solid surface will radiate heat, which is a way of heat transfer. For thermal radiation plumbing, saying it would lead to leukemia or affect vision impossible.

electric heating it so? "Magnetic field 220 volt electric warming caused by electricity home is very weak, far less than the strength of the cause of human disease. A12b34c53fg3p7" said Chen Liping, electric heating heating cable shielding measures, including tinned copper wire and grounding two layers of aluminum foil.

Professor of Energy and Environment, Southeast University Zhang Xiaosong introduced,

electric heating mostly uses 220 volts 50 Hertz frequency power, generally does not produce harmful radiation, and is now with the popularity of computers, television lights, home within the basic environment in the 50 Hz power frequency electric range, electric heating generated radiation on the human body without harm.

[2] harmful gas pipes floor after warm warming?

qualified pipe does not release exceeded the predetermined temperature within the range of harmful substances, emission from heated in winter approaching summer, did not increase significantly.

reporter queried, similar rumors dating back at least April last year, a number of media have been rumors provision. The current "warm six hazard" net culture and the 2005 network, "the six electromagnetic radiation hazard" comparison, except replace the electromagnetic radiation heating radiation, saying almost exactly the same. The "confirmation" section June 24, 2013, "the life of the radiation is not terrible," the article, the experts explained, people's daily called "electromagnetic radiation" is non-ionizing radiation, non-ionizing radiation includes ultraviolet radiation, visible light, mobile phones, electromagnetic computer, power lines, substations, cellular base stations, television broadcasting, etc. was less harmful. Ionizing radiation, including nuclear radiation, X-rays, neutron radiation, harmful.

despite warm itself will not cause harm, but there are friends worry, pipes, floors through to warm "will produce formaldehyde, toluene and other toxic gases butyral After heating to induce cancer." In this regard, Wang Baolong believe, should not be burdened warm "gas release" and "crime" qualified pipe within a predetermined temperature range are not excessive release of hazardous substances.

Wang Baolong said drill a look, the floor temperature may indeed lead to harmful substances, flooring adhesives and coatings of formaldehyde and benzene accelerated to escape, but can be used for qualitative analysis as follows: with wood floors and underfloor heating room, due to attenuation filling layer (or air layer), it was the area floor surface temperature is 24 ℃ -30 ℃ (according to JGJ142-2004 "floor radiant heating technology point of order"); during the summer, the floor surface temperature in this range . Resulting pollutant emission from the floor in winter radiation emission from the floor may be closer to the summer, it would not substantially increase than other heating methods; it has a large number of field test data show that increasing concentrations of indoor pollutants in summer than in winter does not exceed 20%. In addition, now employ more non overhead to warm the pipe will be laid on top of beans stone concrete fill layer, to achieve effective separation, the pipe had no effect on the indoor environment.

[3] How to reduce the harmful gases in the home?

later qualified furniture and diligence window ventilation; after flooring warm, ventilated and heated alternately promote noxious fumes.

Li Wei, said netizens concern decoration materials used in relation to larger, even if there is no floor heating, formaldehyde and other harmful gases will still be in the human body.

Therefore, experts believe, it is important that the purchase duly qualified pipes, flooring and furniture products, and pay attention to ventilation. Deputy director of the Nanjing Hospital of treating disease aftermath Center physician told reporters, such as the use of low-quality furniture, its volatile formaldehyde, paint, stabilizer bad gas, over time may lead to cardiovascular disease, liver and kidney function or damage caused by a blood disease but as long as the purchase of furniture products are qualified through the national quality inspection, materials comply with national standards, the basic do not worry.

addition, "regardless of old and new houses, as long as the people on the ground must live window ventilation, cold weather is no exception." Chen Liping remind the body is not suitable for long-term stay in the heated houses.

Zhang Xiaosong believe that governance is a way of heating the volatile formaldehyde, after the laying of the new house warm, may be airy, alternately heating period of time allowed to accelerate evaporation, and then to live; daily can purchase some or activated carbon plants Wait.

Wei also said that the residents do not recommend tamper with indoor heating facilities, but does not recommend self-floor heating to form, or it may damage the existing pipe network and the heating system, the impact of heat.
