The awareness of floor heating has become higher and higher.
(a) Widespread regional expansion
In China, central heating in winter has been confined to North China and South China, however, the winter in Central Plains, East China and other areas will be below zero 1 to 2 months. With the continuous improvement of people's living standards, the requirements for residential comfort are getting higher and higher. In addition, more and more foreign immigrants have settled in China, which challenges the traditional central heating area restrictions. Therefore, the new independent heating mode has ushered in development opportunities. Floor heating, with its strong flexibility, adaptability and advancement, just meets the needs of market development.
The floor heating is comfortable and the energy-saving effect is obvious. At present, the penetration rate in the "Three North Areas" is rapidly increasing, and the penetration rate in some cities can reach 70-80%, such as Qinhuangdao, Langfang, and Dongying, Shandong. In some areas, floor heating is not a new heating method, but has generally become the first choice for construction units. With the further increase of market demand, floor heating has expanded from large and medium-sized cities to county-level cities, and has made great breakthroughs in the region, such as Shanghai, Wuxi, Nanjing, Hefei, Jiujiang, Zunyi, Guiyang and other low-latitude cities and regions, which quickly accepted and adopted floor radiant heating.
(b) Awareness has been widely raised.
Even in the northeast with high penetration rate, floor heating is extremely difficult in the initial promotion stage, and residents' awareness and influence in the heating field are low. Floor heating initially entered the heating market as a new technology, and the installation process of floor heating was hidden. Early floor heating companies put a lot of effort into recommendation, feasibility analysis, communication design, demonstration between models and project implementation. With the recommendation of designers, the positive choice of construction units, the effect of engineering examples, the floor heating project is increasingly recognized by the society. In the process of popularizing the application of floor heating, the floor heating company has gradually developed and formed a scale. 200 1, there is only one professional water heating market in the northeast market, and some special pipes for floor heating can be seen sporadically. By 2005, at least 80% of urban residents have learned about floor heating, and the proportion of urban buildings, especially civil commercial and residential buildings, has risen rapidly. In 2005, floor heating accounted for more than 30% of the total market share, and this proportion continues to grow.
Floor heating has a broad space for development.
This heating method was recognized as one of the most comfortable heating methods as early as 1930s. It has been used for a long time in many countries in Europe, North America and Asia, and has been widely used. 1994 accounted for more than 50% of the heating market in Germany, Japan and South Korea. However, in China, the floor heating area is less than 10%, and there is a lot of room for development.
Conclusion: To sum up, the initial investment of floor heating system is at a medium level among all heating methods, but it is a high-return investment because of its good energy saving and service life equivalent to that of the building (it is impossible to accurately analyze the benefits of this investment on family health and quality of life here).
Advantages of electric floor heating and other floor heating
1. Electric heating is a new heating mode in China after 2000. From far-infrared carbon heating plate, geothermal cable indirect heating to various direct electric heaters, they have complemented each other in the heating industry for several years.
2. The biggest advantage of electric floor heating is accurate control. No matter how the outdoor temperature changes, no matter how the heating cable fluctuates, due to the use of a very accurate electronic thermostat, the ground temperature and indoor air temperature are basically very balanced and will not fluctuate, which is incomparable to radiator heating and air conditioning heating. At the same time, electric heating will install a thermostat in each room, which makes it easier to control the rooms in time.
3. The development of electric floor heating is more because of its flexibility and intelligence, which attracts many consumers with strong acceptance and recognition.
4. The floor heating industry in China is currently in the stage of large-scale development. This is the result of the efforts of colleagues in electric heating and floor heating. Of course, this is also due to the heating advantages of electric floor heating itself, which has promoted the development of electric floor heating and gradually eliminated the extremely bad influence brought by the failure of the application of ink electrothermal film ceiling heating to government departments, developers and users.
Due to the premise and history of central heating in northern China, the urban heating pipe network has been built. It would be a pity if it is abandoned, and the transformation into electric heating also increases the burden of circuit capacity, which is unrealistic in a short time. Electric floor heating, as a heating supplement for buildings, offices and factories without urban heating pipe network in the north, reduces the initial investment cost of urban pipelines and balances the seasonal differences in electricity consumption. The same is true in the south, where the electricity consumption is the largest in summer, so the circuit design is based on the maximum load. There is indeed a large space for electricity consumption in winter, and the application of electric heating balances the seasonal differences in electricity consumption, bringing benefits to the stability of the country and society, as well as convenience and benefits to users.
6. Electricity consumption is relatively large in summer and relatively small in winter, so electric heating is also a good method and means to balance the seasonal differences of energy. Electric floor heating has not entered the China market for a long time, and there was a power shortage a few years ago. Many people have many misunderstandings about this. With the new understanding of electric heating (win-win for society, users and enterprises), the development of electric heating will surely reach a new height.
With the stability of electric energy and the expansion of peak-valley electricity price, the advantages of electric floor heating are constantly highlighted.
7. Electricity price: it is the most stable energy price at present. In the past 30 years, the electricity price has increased by 3-4 times, while the prices of natural gas and oil have increased by 15-20 times. Judging from the year-on-year economic development, the electricity price has a steady downward trend, while the price uncertainty and upward trend of other energy sources are obvious, which is also proved by the history of developed countries abroad.
8. The invention directly converts electric energy into heat energy without water, thus saving valuable water resources. It solves the problems of building boiler room, storing coal, stacking ash and erecting pipe network, which is beneficial to urban planning. Moreover, the system is completely waterproof and the joints are waterproof, so the whole system is moisture-proof. The service life of electric floor heating system is more than 50 years, and it hardly needs maintenance. There are no headache problems such as running, leaking, dripping and leaking of water heating system, and freezing and cracking of radiator.
9. In the northern area, among buildings with floor heating system, buildings with electric floor heating system account for 5% ~ 10%.
10, the advantages of electric floor heating are obvious: electricity is the cleanest energy from the perspective of energy saving and emission reduction, and it will never be excluded from the heating market from the perspective of emission reduction. The relief of power shortage will definitely bring good news to electric floor heating.
1 1. At the market level, because the electric floor heating market has not really flourished, the competition is not very fierce, at least not as fierce as the circular system. However, with the gradual maturity of electric floor heating market, the market prospect is broad.
12. Combining several points to promote the development of electric heating,
First, the comfort is superior, and the temperature control in each room is accurate (one temperature control in each room).
The second is the controllability of the system to meet the individual needs (smarter control, including the combination with smart home in the future, leads to the new trend of heating)
Third, it has long service life, no maintenance, and is safer and more reliable than water heating.
Fourth, it is the cost advantage of investment and use (which will become more and more obvious).
7. Pay attention to seven problems to make floor heating safer.
1). Try to use marble, floor tiles or floors. If you choose wooden floor, you can only choose composite floor, not solid wood floor. The wood floor has good thermal stability and low moisture content, and the floor is not easy to deform after heating; The floor size should be thin but not thick, narrow but not wide to meet the requirements of deformation resistance and conductivity; The cushion under the floor should not be too thick, and it should be conducive to heat exchange and conduction. Be sure to choose the floor with less harmful substances such as formaldehyde to avoid the floor from releasing more pollutants due to baking, which is harmful to health.
2) Try not to do large-scale decoration (such as carpet) on the floor. Restless legless furniture can avoid reducing the effective heat dissipation area and weaken the thermal effect caused by hot air flow.
3). Ordinary foamed plastic products are not placed on the floor. Due to the poor thermal conductivity of these articles, it is easy to cause heat accumulation, and it is easy to produce harmful gases under the action of long-term high temperature, which is harmful to the health of residents.
4). Turn on the floor heating system and slowly heat up. Don't be too hasty. It's best to raise the temperature by about 1℃ within one hour. Keep the floor clean and dry before heating to prevent the floor from cracking and twisting due to excessive heating.
5). Don't hit, knock or push any sharp objects on the ground. The floor heating pipe laid under the ground is only about 3-4cm away from the floor surface, so it is easy to be injured if you don't pay attention.
6). After the floor is paved, it is best to do environmental protection acceptance. Because the floor used as a floor heating system is a composite floor, there is a problem of formaldehyde release, and when used as a geothermal floor, it will aggravate formaldehyde release after heating. Therefore, after the geothermal heating floor is laid, environmental protection acceptance must be carried out to ensure that the release of free formaldehyde reaches the standard. You can't buy cheap goods that are not environmentally friendly at high prices, otherwise there will be endless troubles!
7). Choose professional brands and products with excellent performance. Choose a professional and powerful formal company, and don't covet cheap to find small manufacturers and mobile vendors. The floor heating industry is known as "three-point product and seven-point installation". Floor heating is a systematic project, which needs professionals to design and operate from scheme design, product selection, construction and installation to after-sales service. If something goes wrong in a certain link, it will be very difficult to maintain, and the project will be arduous and complicated, which will even affect the normal use of the whole heating system or greatly reduce the service life of the whole system. Not only that, but also the foreshadowing will be laid later.
