1. "Where is the floor to warm the floor?"
"Your floor can be floor heating?" Purchasing guide replied: "There is absolutely no problem, special floors for geothermal." Almost every floor selling the answer is so very positive, but also took out user examples, and some also took out the test According to the report, consumers feel that “all floors should be floor-heated.†They do not know that they are suitable for floor heating to meet four major factors: floor heating conductivity, dimensional stability, pollution prevention and environmental protection, and durability.
The flooring industry is developing floor standards, quantifying the four major elements, and laying down standards for floor inspections and quality inspections during the warranty period to quantify the technical indicators for laying and maintenance.
2. "Is the name of the dedicated geothermal floor right?"
In the current floor circulation market, floors used for floor heating are not only diverse but also have more disorderly names. For example, "heat-resistant floor", "anti-heat floor" and "heat-resistant floor", etc. The most popular is "heating floor". "floor heating floor" "heat-resistant floor" "geothermy floor" "dedicated geothermal floor" and so on, we think some names are not scientific, some names seem to not be appropriate, the current ground radiant heating system in particular, is booming, the name must Standardization, it should be said: "floor heating," the definition should be: suitable for the floor surface of the radiant heating system laying the wood floor, and through the board to the room to transfer heat.
3. "The thicker the floor, the more insulated it?"
The thickness of the wood floor is a factor that determines whether or not the foot feels comfortable. Therefore, many consumers require a floor thickness of 15 to 18 mm when purchasing flooring, especially solid wood, multi-layer solid wood floors, or bamboo flooring. Therefore, when they choose to warm the floor, they also use this method to pick, but they do not know that wood is a poor conductor, usually the thermal conductivity of wood material is between 0.17-0.34, while water is 0.5. If the thickness of the floor is too thick, it is more detrimental to heat conduction through the floor to the board surface, and it is consumed in the conduction process. As for insulation, the temperature difference between the upper and lower floors is bound to cause great deformation of the floor, "heat expansion and contraction," "swelling shrinkage" will cause the floor scoop, twist, bend, crack, dimensional stability can not be guaranteed.
4. "Is the geothermal heating floor specification too wide?"
Now consumers buy solid wood flooring first to live comfortably, and secondly to show their identity. Therefore, in the purchase will often choose those larger specifications of the floor, especially the width direction, and some up to 180mm. This width, in the daily floor pavement experts do not recommend the user to buy, so as to avoid the floor due to the expansion of the wet shrinkage from the gap, not to mention in the case of heating the floor, due to the distribution of water faster, even more Prone to floor separation. Therefore, experts recommend that consumers do not buy oversized floors when purchasing geothermal heating floors.
5. "Is the floor mat with aluminum membrane special for floor heating?"
This is the most typical misleading. Practice has long proved that: In the ground radiation heating system, the heat transfer is mainly radiation, followed by convection, and finally conduction. If aluminum foil is covered on the cooling floor to form a reverse radiation, the surface temperature is kept the same when the floor is warmed. Underneath, the foam pad with aluminum film has a large thermal resistance, while the ordinary foam pad has a small thermal resistance. Obviously, an ordinary foam pad has a better heat conduction effect than a foam pad with an aluminum film, and is more conducive to heat conduction from the floor to the room. Therefore, when the user chooses to warm the floor, he or she should choose ordinary foam mats or material mats with low thermal resistance, moisture resistance, and corrosion resistance to lay.
6. "Can I add plywood or blockboard under the floor?"
First of all, the laying of plywood or blockboard below the geothermal heating floor is not conducive to the conduction of heat, which virtually increases the loss of heat in the conduction process and increases the heating cost of the geothermal heating system. Secondly, if the quality of the plates purchased does not pass, the free formaldehyde content in the room will exceed the standard, or because the moisture content is not up to the standard, moisture will be absorbed by the floor after laying, and the floor will be tiled, arched and so on. This substrate board has many advantages and disadvantages. It can be said to be self-defeating and superfluous! It is even more forbidden to lay down the floor.
7. "Can only suspend laying method?"
Due to the special structure of the geothermal heating system, the cement floor cannot be nailed when paving the floor. Therefore, for a long time, most of the pavements for geothermal floors only recognize suspended paving. In fact, with the continuous advancement of science and technology, there are two other paving methods: floor bonding and keel laying. Recently, there has appeared a kind of quick mounting keel on the market. This type of keel can be installed without nails. The keel can be directly fixed on the concrete floor with glue, and then the keel can be fastened to the floor through the buckle on the keel. Keel on. This will not only increase the floor feel, but also leave space between the keel, so that the air can convection up and down the floor, is conducive to the circulation of heat convection, and make the floor more uniform heat, deformation, heat efficiency of the room is higher. This is a respectable laying method for the current value.
8. After the floor pavement is completed, the floor heating test is not performed. After the geothermal heating floor is installed, in addition to the routine acceptance, the most important thing is to check the temperature of the floor. When the floor is laid, it is warmed up after completion of work or after entering the winter. When the system is warmed up for the first time, the temperature should be raised slowly. When the base floor is heated to 25°C, it should be heated for 12-24 hours. Afterwards, slowly warm up to the required room temperature (14-22°C) at 1°C/h. The temperature should not be too high, and the wooden floor surface temperature should be ≤28°C. In a short time, the limit temperature is less than or equal to 32°C. The higher the temperature, the greater the loss of heat energy, the shorter the life of the thermal system, and the more prone to hidden dangers. Moreover, the floor is prone to deformation such as scooping, twisting, bending and cracking.
9.Paving is not done because of the environmental protection acceptance. Because the floors used as floor heating systems are mostly composite flooring (solid wood composite, reinforced and bamboo flooring), there is a problem of formaldehyde emission in itself, and when it is used as a geothermal floor, After heating, the release of formaldehyde is exacerbated. Therefore, after paving geothermal floor heating, we must do environmental protection acceptance to ensure the release of free formaldehyde to meet the standard requirements (national standard is 1.5mg/L), in order to enable the normal use of the floor, be sure to buy two Points: 1 The floor should be used for environmental testing before warming the floor. The general inspection is free of charge, and the treatment must be charged. After inspection, it is checked for environmental protection acceptance. 2 Floor and accessories environmental indicators must be up to standard. Can not afford to buy the price of cheap environmental protection, or endless trouble.
10. Laying a legless combination furniture or a rug on the floor, destroying the floor cooling surface With the continuous improvement of the living standards of modern people, people are increasingly pursuing personalization for home improvement, so many personalizations came into being. Assembling furniture, it can be arbitrarily assembled according to the owner's preferences. However, these furniture are often legless furniture that are in direct contact with the ground. If the room is paved with geothermally-heated floors, the furniture, carpets and the floor will be covered directly, which will cause the floor to be heated and uneven due to heat not being able to dissipate, resulting in floor deformation and other conditions. , Waste of heat, so that the temperature of the room to chat.
