Geothermal floor many kinds, characteristics vary. So many consumers often because listening to different Purchasing Guide describes the time of purchase, and by a variety of conflicting claims confused, which made the wrong choice. Geothermal floor in order to prevent users are "bought the wrong," the regret opportunity:
First, more than 80% of the composite to heat the floor hazardous formaldehyde
Any composite flooring (including strengthening, multilayer and solid wood three wood, etc.) require the use of glue, and the glue will contain formaldehyde. Formaldehyde is characterized by volatile point of 19 , temperature rise per 1 , formaldehyde emissions will increase by 15% -30%, so the normal standards of laminate flooring, will be used in the warm formaldehyde. 315 During the year, Zhejiang Province, the Consumer Council announced the results of an experiment: 15 lots at room temperature, consistent with the requirements of the composite class E1 grade geothermal floor, at 40 environment, there is 87 percent more than the national standard formaldehyde emission, excessive the highest is more than the national standard of 20 times; several well-known brands of composite warm floor also has six times more excessive.

Currently, only pure solid wood to heat the floor and it did not add industrial formaldehyde, formaldehyde warm hidden does not exist.
Second, the general multi-floor heating wood could be used to crack
Multilayer wood flooring by the deformation of different hardwood veneer and plywood multilayered pasted together. Because of different materials, in warm environments, shrink large hardwood table plate and the substrate shrinkage of small fast-growing wood, for example: from summer to winter after geothermal open, with the moisture content decreased, the amount of shrinkage of fast-growing base of only 0.15mm, if the surface layer of wood species Balsamo, its shrinkage was 2.2mm, a difference of nearly 15 times. In this case, the table plate to maintain the same size of the substrate, the equivalent of being stretched 2mm, when the tensile stress is greater than the tensile strength of wood stripes, floor table board to produce cracking. It was found that the wider the floor more prone to facial cleft, thicker skinned more easily deformed.

Many commercially nominal "applies to warm" multilayer wood flooring is mainly the panel is easy to crack
Third, for the warm, thick surface layer parquet tile becomes easy bagging
Many consumers buy geothermal parquet floor that surface layer thicker the better, the closer the natural quality of pure solid wood to heat the floor. In fact, when the face layer thickness of 4mm or more, due to the parquet in a warm environment, large surface shrinkage, the floor surface under tension will produce high-middle and low ends of U-shaped tile change; in the wet environment, expansion stress floor surface is greater than the base, it will have a low floor intermediate the ends of the n-shaped tile becomes high. Floor width wider, thicker surface layer, tile becomes more obvious.
