Expert Tip: Selection, Installation and Use of Geothermal Soils
1. Selection of geothermal soils
It is recommended to choose composite soils. Since the thickness of composite floors is generally 7-8mm, it is easy to conduct the heat generated by the geothermal system to the surface. In addition, the surface of the composite floor is a layer of metal oxide resistant to wear and therefore heat. diffuses very quickly and evenly on the surface. The solid wood floor is relatively thick, generally about 2cm thick, and keels are required during installation, so the heat from the geothermal system is not easily conducted to the surface and the coefficient of thermal conductivity of wood is very low, which will This will cause heat loss and also increase the surface temperature. It is unequal and the temperature difference is tvery obvious.
The quality of imported floors reaches the European standard Enpr13329, and the quality of domestic floors reaches the national standard GB/T1802-2000. Both can adapt to the technical requirements of the current geothermal floor heating installation. , some qualified brands in the market have reached this standard. The effect of locked ground is better. As there are small gaps between the hung floors, it is not easy to deform after expansion.
In order to increase heat conduction, the thickness of the cushion and floor material should not be too thick. The standard thickness of geothermal flooring is 6.5-8.5mm, laminate flooring is 6-8mm and three. Solid wood composite flooring should be 8-9mm. Consumers are recommended to be careful when choosing and try to choose a small size, preferably a square or herringbone shape of 200 × 40 × 10, so that the deformationthermal mation can be. even. If you choose laminate flooring, you can choose special geothermal floors from well-known brands such as Shengxiang, Sihe, Ruijia, Hongnai, Oudi and Baili. These manufacturers have strict requirements regarding the density of the base material. The same thickness has high strength, good air permeability and heat dissipation function, and the heat resistance has been specially treated. If you choose solid wood composite flooring, you can choose special geothermal floors and geothermal floors of well-known brands such as Fumandi, LG, Yinqiu and Shiguang

In order to increase heat conduction, the thickness of the cushion and floor material should not be too thick. The standard thickness of geothermal floor is 6.5-8.5mm and the thickness of laminate floor should be 6.~8mm, three-layer solid wood composite flooring 8~9mm. Consumers are recommended to choose carefully and try to choose a small size, preferably a square or herringbone shape of 200 × 40 × 10, so that the thermal deformation can be uniform. . If you choose laminate flooring, you can choose special geothermal floors from well-known brands such as Shengxiang, Sihe, Ruijia, Hongnai, Oudi and Baili.

2. Pay attention to the treatment of the floor before installation
As a floor installation using geothermal heating with water circulation heating, special attention should be carried out to treat the ground before installation. . The area within 2 meters should be flat and the height difference should not exceed 3mm. The ground must be completely dry. When installing the floor, supervise the installation workers so that they do not lose holes or nails in the floor to avoid geothermal pipes leaking, which will cause the geothermal system to lack water and soaking the soil in water and disposing of it.
3. There are special paper mats for installinge geothermal heated floors. Ordinary plastic foam mats cannot be used.
When installing geothermal heated floors, be sure to use special geothermal paper floor mats. This type of floor mat has the characteristics of fast heat conduction and non-deformation, and ordinary foam floor mats cannot be used. Foam floor mats conduct heat slowly and are likely to produce harmful gases when exposed to high temperatures for a long time, endangering the health of consumers. At present, when installing geothermal floors, imported ground mats are mainly used. Household paper floor mats are easily deformed when exposed to heat and damage the floor.
4. The heating procedure should be gradual
The temperature should be increased onntly when it is heated for the first time or when it has not been used for a long time. It is recommended to do so. increase the temperature about 1 degree per hour to prevent the floor from cracking and warping too quickly.
Considering that any floor has the defect of expansion and deformation when exposed to heat, when consumers use the geothermal heating system in the second year, they must strictly follow the procedures prescribed heating steps, step by step, and should not heat in a single step, like the first The temperature only rises to 18 degrees Celsius one day, 25 degrees Celsius the next day, 30 degrees Celsius the third day, and so on. following. Laminate flooring is suitable for water pipe temperatures not exceeding 45 degrees Celsius and floor surface temperatures not exceeding 30 degrees Celsius. If this temperature is exceeded, the lifespan and land use cycle will be affected. Generally, the indoor temperature of a house in winter is very comfortable when it reaches around 22 degrees Celsius, so as long as the temperature rises normally, it will not affect the use of geothermal ground in the coming year .
