1. Do Shanghai and East China need heating?
Although the temperature in Shanghai is not very low in winter, due to high air humidity and large heat loss from the human body, it is easy to feel cold and unbearable, and sometimes it even feels colder indoors than outdoors. This kind of climate can easily affect the growth of children and induce diseases in the elderly. Compared with foreign countries, cities with a similar climate to Shanghai have heating. Throughout history, buildings, new lanes, villas, etc. in old Shanghai also have heating facilities. Since the founding of the People's Republic of China, due to restrictions on national heating and ventilation design, residential buildings have been without heating. Now, with the adjustment of national policies and the improvement of residents' living standards, heating has become a necessity for high-quality life. Therefore, heating is necessary in Shanghai and East China.
2. What is the most effective heating method at present?
Decades of heating experience in developed countries have proven that the most effective method is ground radiant heating. The temperature distribution of floor heating is low and high, which meets the physiological needs of the human body to keep the feet warm and the head cool. It feels the most comfortable and has incomparable advantages with other heating methods. It is recognized as the most scientific and reasonable, the most comfortable and healthy, and the most economical and energy-saving. Heating methods. In addition, floor heating also has many advantages such as safety and durability, green and environmentally friendly, economical, easy to manage, maintenance-free, and value-added property. Floor heating has become popular in my country rapidly and has become the first choice for many families pursuing high-quality life.
3. What are the methods of floor heating?
At present, there are two main ground heating methods with mature technology: one is the heating cable floor heating system, and the other is the hot water floor heating system. Both methods have their own characteristics. Regardless of the cost performance of the system or the use experience in developed countries, the heating cable floor heating system is a relatively ideal choice.
4. Is using a floor heating system good for your health?
Of course it’s good for your health. First of all, the current floor heating system senses heat from bottom to top, which is in line with the traditional Chinese medicine theory of "warmth starts from the feet", making the whole body comfortable and more beneficial to diseases such as arthritis and cold legs that are common in the elderly. At the same time, it eliminates the shortcomings of hot air, noise, dryness, and bacterial transmission caused by heating equipment such as air conditioners.
Secondly, the far-infrared wavelength of floor heating is between 8μm and 13μm. It only stimulates the acupuncture points 2mm inside the skin surface, which are called "sensitive temperature points", making people feel a mild body sensation. It gives people the natural warm feeling when basking in the sun, which can strengthen the body and maintain health.
Thirdly, because the heat rises from the ground instead of the heat cycle of air conditioners and electric heaters, it is very beneficial to asthma patients and is recommended by asthma foundations in many countries.
5. What is the installed power per square meter?
Depending on the conditions of the place of use and the user’s temperature requirements, the installed power in indoor places is generally 80W/m2-160W/m2.
6. After installing floor heating, how much should the floor of the room be raised?
If a composite floor is used, the height of the composite floor should be 2cm-3cm higher than that of a normally laid composite floor, because the ground insulation layer needs to be laid and covered with a cement layer for heat storage and leveling. If a solid wood floor is used, the heating cable will be laid in the keel under the wooden floor, and the ground will basically not be raised.
7. At what stage is it appropriate to install floor heating and how long will the construction period take?
The construction period only takes two or three days, and installation is generally required after all the water and electricity processes are completed. In addition, the laying of the floor heating system must be coordinated with the decoration company to ensure the construction quality of the floor heating system.
8. After installing the floor heating system, how should you choose wooden flooring?
Based on the comprehensive evaluation of factors such as heat transfer effect and thermal stability, the surface material on the floor heating system should be the first choice for solid wood composite flooring (of which dedicated floor heating flooring is the best), followed by reinforced composite flooring. floor. In general, tree species that are lighter in weight, have less shrinkage, and have good thermal stability are more suitable for use in floor heating systems. But no matter what kind of floor is used, its moisture content index should be below 12.
In addition, it is necessary to choose floors with high density, good base material stability, and good environmental performance, and choose products from well-branded and powerful manufacturers. Of course, it is best to use wooden floors dedicated to floor heating, and obtain the support from the manufacturer. Suitable for underfloor heating commitments.
9. How high a temperature can be achieved using floor heating?
Depending on the choice of floor surface materials, the floor surface temperature that can be achieved by the electric floor heating system installed in different places such as bathrooms, living rooms, bedrooms, etc. is 25℃~35℃, but the actual temperature that can be achieved in this place The air temperature (i.e. room temperature) depends on the overall insulation performance and heat loss of the room. Under a certain power configuration, the better the overall thermal insulation performance, the less heat loss, and the smaller the ambient temperature difference, the higher the room temperature that can be achieved. Therefore, we recommend retrofitting wall insulation in rooms where electric floor heating systems are installed, and using double-glazed windows to reduce heat loss. Generally, the comfort required for overall heating can be guaranteed when the room temperature reaches 18-21°C.
The maximum operating temperature of the heating cable itself is about 65°C.
10. How to control the floor heating system?
The floor heating system uses a thermostat for switch control and temperature adjustment. The thermostat is composed of high-precision electronic components, has automatic temperature setting function, beautiful appearance, and is easy to operate. The digital LCD thermostat can automatically control the temperature according to programming, and the temperature can be preset in daily and weekly time periods to achieve Energy saving and intelligence.
It is recommended that in daily use during the heating season, it is better not to turn on and off frequently and let the electronic thermostat automatically adjust. This can save more energy.
11. Will the long-term heating of the composite floor by the floor heating system have an impact on the performance of the floor?
Qualified quality laminate flooring is pressed at high temperatures and has very little internal moisture content, so the floor will not be deformed due to the loss of moisture. Moreover, the surface temperature of the geothermal system is generally below 30 degrees Celsius, allowing the indoor temperature to reach about 20-25 degrees Celsius. This temperature is almost the same as the indoor temperature in most homes in summer. The temperature of the composite floor surface when it is illuminated by the sun is sometimes even higher. Above this temperature, heating itself has no effect on qualified composite flooring.
12. How much electricity does an electric floor heating system consume?
The power consumption of the system depends on many factors such as the installed power, the thermal insulation performance of the building itself, and the room insulation performance (such as whether the floor heating system has integrated corner insulation and whether wall insulation is used). . A room with better thermal insulation saves more electricity. The higher the outside temperature, the more electricity it saves. The user's personal habits also determine the amount of electricity used. The electric floor heating system will determine the working power required for each room based on comprehensive factors such as the owner's usage area, room orientation, insulation conditions, users' personal habits, and floor auxiliary materials, so as not to cause a waste of energy or a loss of working power. insufficient. Generally speaking, the installed power in indoor places is 80-160W/square, and in most cases it is around 120W/square. When the set temperature is reached, the heating will automatically stop and enter the heat preservation and energy-saving state.
Under the current domestic building standards, the power consumption of electric floor heating systems in Shanghai during the heating season is generally: 0.5-0.7 degrees/square meter/24 hours. If the building's thermal insulation performance is better or an intelligent electronic thermostat is selected, this energy consumption value can be further reduced.
13. How long is the service life of electric floor heating?
The heating cable has a working life of at least 50 years at room temperature. In fact, heating cables installed in the concrete layer are equivalent to wires buried in the wall. Did you remember to replace the electrical wiring within the wall? In fact you are barely aware that these wires are there. Therefore, it can be considered that the floor heating system is basically equivalent to the life of the building.
14. If there is a problem with the heating cable in the concrete, how to repair it?
Once the heating cable is installed correctly according to the instructions, the chance of operating failure is minimal. If a problem occurs, it is usually due to external mechanical damage, such as screws driving into the concrete layer and damaging the cables.
In this case, the location of the fault is immediately identified, the concrete in the area is removed, the damaged section of cable is cut, the cables are joined together and repaired and insulated with special repair material. In other more complex situations, professional instruments can be used to confirm the location of the fault and repair it.
15. Is electric floor heating safe?
First of all, from the perspective of the cable structure, the heating element must first be wrapped with an insulating layer, then a tinned copper wire for grounding protection, and then put on an aluminum metal sleeve to make continuous and durable contact with the grounding wire. Eliminate electromagnetic radiation, enhance the waterproof performance and mechanical strength of the cable, and finally protect it with an insulation layer on the outside. This multi-layer insulation structure ensures the safety and reliability of our heating cables.
Finally, our heating cables are paved in a 2-3cm thick cement layer to further ensure safety.
16. Will floor heating increase the release of formaldehyde and other harmful substances?
In international standards, the formaldehyde release standard in composite flooring is very strict, which absolutely meets environmental protection requirements, and its index itself is far lower than that of decorative materials such as large core boards. The temperature change of the geothermal system does not It does not exceed the range of normal indoor temperature changes, so as long as you choose a floor that meets international standards, it will not increase the amount of formaldehyde released by the floor.
17. Can electric floor heating be used in humid rooms?
Yes. The heating cable is waterproof and has undergone strict insulation testing before leaving the factory. In fact, in Northern Europe, electric floor heating is the preferred heating method in bathrooms and other places where the ground is often wet. If floor heating is not used in these places, the human body in contact with it will feel cold.
18. Will the electric floor heating system produce harmful electromagnetic radiation areas?
All electrical equipment (such as TVs and mobile phones) will emit electromagnetic radiation when used. As long as the electromagnetic radiation is controlled within national standards, it will not have a negative impact on the human body. Our heating cables are double-shielded with grounded copper conductors and metal aluminum sheaths to eliminate electromagnetic fields. Moreover, the cables have passed electromagnetic radiation tests by professional testing institutions. The electromagnetic radiation generated by the system is far less than the existing standard value for health requirements. So you can use it with confidence. ?
19. What stage of floor heating construction is more appropriate and how long will the construction period take?
Floor heating can be carried out after the completion of the water and electricity transformation process, or it can be combined with water decoration, strong and weak electricity System modifications are carried out in conjunction. For a flat-story house with a simple control of about 120m2, the construction period of floor heating is 2-3 days. The backfill layer conservation period will vary according to the season: for split-level houses with higher control system requirements, the construction period will take - one week. The conservation period of the backfill layer will vary depending on the season. In addition, when laying the floor heating system, great care must be taken to prevent the buried pipes from being damaged by subsequent decoration construction.
20. Will the underground heating pipes of floor heating leak? How to repair them if they leak?
The underground pipes of floor heating are hidden projects. There is no external mechanical damage and they will not leak. . If the buried pipe is damaged by external forces during decoration or use (such as nails or high-temperature heat sources that damage the buried pipe), you should contact the construction unit or manufacturer immediately. Professionals will arrive in time to confirm the fault location and carry out professional repairs to minimize the customer's economic costs. loss.
21. Will the floor be unevenly hot or cold or locally extremely hot?
According to the insulation and heat dissipation conditions of different rooms, room functions, furniture placement, and floor covering selection, The floor heating system is designed in a targeted manner such as the adjustable conditions of the heat source, so that local overcooling or overheating will not occur. In addition, the use of control systems with different configurations will allow different rooms to reach comfortable and satisfactory temperatures. Nowadays, when doing floor heating, many users ask floor heating companies to reduce the distance between buried pipes because they are worried that the temperature will not be enough in the future. Many companies blindly cater to users' ideas, resulting in heating pipes being laid too densely and the overall or local temperature of the room being too high.
