As more and more homes are paved and warm, the geothermal floor is also hot. As we all know, wood flooring is easily deformed by heat, although the thermal insulation of solid wood is good, but the thermal conductivity is not good. What is the geothermal floor? What characteristics should the floor meet the requirements of paving floor heating? What are the requirements for geothermal floor covering? With regard to the purchase and paving of geothermal floors, only by fully understanding can we stay away from worries.
The geothermal floor national standard has not been introduced
I searched the Internet for "geothermal floor" and found that a sentence was reprinted by several websites: "The quality of domestic flooring has reached the national GB/T1802-2000 standard, and all can meet the technical requirements for geothermal heating floor installation." In fact, the national standard for geothermal floor will be introduced, but it has not yet come out.
Carefully read the above sentence, it is not difficult to find flaws: can adapt to the technical requirements of geothermal heating floor installation, is not in line with the standard of geothermal floor installation and use.
Consumers are reminded that the national standard for geothermal floor has not been introduced, and caution should be taken when purchasing.
Floor heating features available
What characteristics does the geothermal floor have compared to ordinary flooring? The geothermal floor requires stronger stability and is not easily deformed under conditions higher than normal temperature; the floor covering material for geothermal has good thermal conductivity and has stronger moisture resistance; at higher temperatures Has better environmental characteristics (low formaldehyde emission) and so on.
Experts suggest that the best choice for laminate flooring is laminate flooring or laminate flooring. Because the thickness of laminate flooring is mostly 7-8 mm, it is easy to transfer the heat generated by the geothermal system to the surface, and the surface of the composite floor is a wear layer of metal oxide. The heat spreads very quickly and evenly on the surface. The solid wood floor generally has a thickness of about 2cm, and the keel is also required to be installed. The heat is not easily transmitted to the surface, and the heat transfer coefficient of the wood is very low, which causes waste of heat, and also makes the surface temperature uneven, and the temperature difference is very obvious.
In addition, in order to increase the amount of heat conduction, the thickness of the cushion material and the floor should not be too thick, the standard thickness of the geothermal floor is 6.5 ~ 8.5mm, the reinforced composite floor should be 6 ~ 8mm, the three-layer solid wood composite floor 8 ~ 9mm. Consumers are advised to use small sizes as much as possible to make them thermally deformed evenly.
What should I pay attention to when installing geothermal floor?
The first is to pay attention to the ground handling before installation. For the installation of plumbing floor, pay attention to the treatment of the ground before installation. The floor of the floor with floor heating must be horizontal within a radius of 2 meters, the height difference should not exceed 3 mm, and the ground should be completely dry. During the installation of the floor, the supervisory installation worker must not drill the nails on the ground to avoid leaking the geothermal pipeline, so that the geothermal system runs water, and the floor water is scrapped. Secondly, to install geothermal heating floor, it is necessary to use geothermal special paper mat, which has the characteristics of fast heat conduction and no deformation. Can not use ordinary foam floor mats, foam mats are slow in heat conduction, and long-term exposure to harmful gases under high temperature, endangering the health of consumers.
Tips: Geothermal floor maintenance
1. The first heating should be gradually heated for the first time or when it is not used for a long time. It should be slowly heated. It is recommended to raise the temperature by about 1 °C per hour to prevent the wooden floor from heating up too quickly and cracking and twisting.
Considering that any floor has the defect of thermal expansion deformation, when using the geothermal heating system in the second year, it must be strictly in accordance with the prescribed heating procedure, and must not be warmed up in one step, such as heating up to 18 °C on the first day, the next day. It rises to 25 ° C, and the temperature rises to 30 ° C on the third day.
2, the surface temperature can not be too high to use geothermal heating, the surface temperature should not exceed 28 ° C, the water pipe temperature can not exceed 45 ° C, beyond this temperature, will affect the life of the floor and the life cycle. The average family, when the room temperature reaches 22 °C in winter, is already very comfortable. If the temperature rises normally, it will not affect the use of geothermal floor.
3. Turn off the geothermal system and reduce the temperature. When the indoor heating system is no longer needed, it should be noted that there must be a process to shut down the system. The cooling process of the floor should also be descended step by step, and it should not dip. If the cooling rate is too fast, Will affect the life of the floor.
4, when the room is too dry, you can consider humidification If the climate is dry, plus the use of geothermal heating, the floor is at high temperatures for a long time, easy to dry, then it is necessary to humidify the room to avoid dry deformation of the floor.
Because the surface temperature of the floor is relatively high, in the room where the geothermal heating system is used, it is better not to place the glassware and porcelain containing water directly on the ground in winter to avoid uneven heating, thermal expansion and contraction, and the vessel is broken.
