Strong cold wave strikes geothermal floor performance determines quality

Interpretation of performance

1, excellent thermal conductivity

Both wood and bamboo are good natural materials. The ground heat is transmitted to the surface through the floor and there is bound to be heat loss. The ideal floor can minimize these losses. Therefore, in order to reduce the loss of thermal energy and reduce the heating operation and maintenance expenses, the floor heating floor must be "thickness is not selected thick." Optional multi-layer solid wood, bamboo flooring and laminate flooring, the thickness of not more than 8 mm, the maximum can not exceed 10 mm.

  

2, the material stability is better

The use environment of geothermal floor is complicated, especially in the northern area, the ground in the non-heating season is subject to all kinds of moisture, and the temperature of the ground when heating is increased suddenly, the floor will inevitably bear the double change of “temperature” and “humidity”. Therefore, geothermal floors must be purchased with good stability materials, such as laminate flooring, multi-layer solid wood flooring, bamboo flooring, these integrated composite flooring.

3, strong moisture resistance and heat resistance

The adhesives should be used for the integrated composite floor. The adhesives must meet the three major indicators of environmental protection, bonding strength, and high temperature and humidity resistance. In particular, for geothermal floors, we must go through experiments such as high humidity resistance and low temperature resistance. If ordinary adhesives are used, environmental indicators, moisture resistance, aging resistance, and expansion rate cannot meet the standards. Therefore, when a consumer purchases, it is necessary to check the product report and inspection report of the merchant.

4, long-term wear resistance

Because the geothermal floor should not be thick, the composite surface layer is generally 0.3-0.6 mm. The main surface of the paint wear resistance than traditional indicators.

   

expert's point

Geothermal floor is not thicker and warmer

Industry sources told reporters that the floors that are more suitable for geothermal heating methods should be laminate flooring and parquet.

Geothermal floor must have good heat transfer performance, good thermal stability, good environmental performance, good anti-deformation performance "four good" requirements. Ground heat is transferred to the surface through the floor, and there is bound to be heat loss. The ideal floor can minimize these losses. Therefore, in order to reduce the loss of thermal energy and reduce the heating operation and maintenance expenses, the floor heating floor must be "thickness is not selected thick."

The reporter found in the interview that although the merchants claimed that they could be used for geothermal heat. However, according to experts, of these, 55% of them cannot be used in heating systems, and 25% can be used for floor heating, but the effect is not ideal. Only 20% of them are dedicated geothermal floors. Therefore, experts advise consumers to pay attention to certain misleading claims, such as "the thicker the foot feels better" and "the thicker the more thermal insulation", the special geothermal floor has foam pad and aluminum foil on the back, and the box is printed with "Hard room only" is the floor heating. As everyone knows, these arguments are unreasonable; they only affect the cooling of the ground.

Choose floor mats to reject foam

As a geothermal heating method using water circulation heating, in the actual application and installation process, in addition to the choice of floor, the treatment of the ground before installation will also play a decisive role in whether the geothermal heating system can be used normally. The role.

Before the floor is installed, the ground should be strictly controlled according to the standard of the national standard and then installed. When the floor is installed with geothermal heat, strict implementation of the standards is required to ensure that the geothermal heating system will be used in the future. The normal operation.

Experts said that in the geothermal heating system, the correct installation method is to add a layer of mats between the floor and the ground. This floor mat is preferably imported professional paper mats, because imported professional paper mats have Heat conduction, no deformation and other characteristics. When consumers choose floor mats, they can neither use domestic nor imported foam materials because foamed mats will produce harmful gases when the geothermal heating system is heated, which will adversely affect the health of consumers. .

Considering that any floor has the defect of heat deformation, when the consumer uses the geothermal heating system in the second year, it must strictly follow the prescribed heating program to cycle progressively, and must not be warmed up in one step. For example, only warm up to 18 degrees Celsius on the first day. , the next day 25 degrees Celsius, the third day of 36 degrees Celsius and so on. Laminate flooring is suitable for pipe temperatures not exceeding 45 degrees Celsius and floor surface temperatures not exceeding 30 degrees Celsius. If you exceed this temperature, it will affect the life of the floor and the life cycle. The average family's indoor temperature in winter reaches around 22 degrees Celsius and it is already very comfortable.
