What kind of floor is suitable for geothermal heating?
The choice of a geothermal floor should be chosen to adapt to the floor where heat and cold are repeatedly transformed and conducive to heat conduction. Should meet the following points:

First, the dimensional stability is better
The main consideration is the density and internal bond strength of the flooring substrate. Floors with high density and high internal bond strength can guarantee long-term high temperature without cracking and deformation.
Second, fast heat transfer, not afraid of high temperature
The thickness of the floor and the heat transfer coefficient are better. For the reinforced wooden floor, the decorative layer of the product is required to have stable performance, and the long-term high temperature does not fade or rough.
Third, not afraid of the humid environment
Floors used for hydrothermal heating require a water-absorbing thickness expansion rate of less than 2.5% so that the floor has a small dimensional change at high temperatures.
Fourth, low formaldehyde content
In order to avoid harm to the human body, the amount of formaldehyde released from the floor should not exceed the limit during long-term heating.
In general, laminate flooring is more suitable for geothermal flooring. Because the solid wood floor is generally thick, the keel will be installed during installation. If it is used as a geothermal floor, there will be air between the floor and the ground. The thermal conductivity coefficient of air and wood is very low, so that the heat is not easily transmitted to the surface, which leads to waste of heat, uneven surface temperature, and obvious temperature difference. In addition, solid wood flooring has a high moisture content and is heated at high temperatures for a long time, which is prone to cracking and deformation.
The laminate flooring because of high temperature suppression, the internal water content is low, the floor is not easy to deformation. Due to the criss-cross structure, the multi-layer engineered wood floor decomposes the stress generated by the heating surface, and the deformation is also small.
