What is the best heat source for floor heating in Sihong?

With its energy saving, environmental protection, comfort, health and other characteristics, electric floor heating has quickly entered the heating market and gained people's recognition. Electric floor heating has many advantages over water floor heating and occupies most of the floor heating market share. Coupled with the rising price of natural gas, the trend of electric floor heating replacing traditional heating as an energy-saving and comfortable heating method is irreversible. As people's demand for comfort in the built environment increases, urban building heating energy alone accounts for nearly 10% of the country's commercial energy consumption. Building energy conservation work is urgent. Building energy conservation includes two parts: envelope structure and heating system. At present, in terms of construction, insulated walls and insulated roofs have been used to strengthen the insulation of the envelope structure, and double-layer glass has been used to enhance the air tightness of the envelope structure to achieve energy saving. The energy saving of the heating system can be achieved by improving the heat source of the heating system (boiler room and thermal war) and the thermal efficiency of the indoor heating system. Floor heating as a new heating method has been increasingly recognized by people. Floor radiation The trend of heating as an energy-saving and comfortable heating method to replace traditional heating is irreversible.

The awareness of floor heating is getting higher and higher

(1) Expansion of popular areas

In China, central heating in winter has always been limited to the three north areas. and North China. However, in the Central Plains, East China and other regions, subzero temperatures last for one to two months in winter. As people's living standards continue to improve, their requirements for residential comfort are also getting higher and higher. In addition, more and more foreign immigrants have settled in China, posing challenges to the traditional central heating area restrictions. New independent heating methods therefore usher in development opportunities. Floor heating, with its strong flexibility, adaptability and advanced nature, just meets the needs of market development.

Ground heating is comfortable and has obvious energy-saving effect. At present, the popularity of floor heating is increasing rapidly in the Three North Areas, and the penetration rate in some cities can reach 70-80%, such as Qinhuangdao, Langfang, Hebei, and Dongying, Shandong. In some areas, floor heating is no longer a new heating method, but has generally become the first choice of construction units. As market demand further increases, floor heating has been promoted from large and medium-sized cities to prefecture- and county-level cities, and has made major regional breakthroughs. Low-latitude cities and regions such as Shanghai, Wuxi, Nanjing, Hefei, Jiujiang, Zunyi, and Guiyang have quickly accepted it. And uses floor radiant heating.

(2) Awareness is widely increased

Even in the northeastern region where the popularity is high, floor heating is extremely difficult to promote in the initial stage. Residents’ awareness, The influence in the heating field is low. Floor heating initially entered the heating market as an emerging technology. The installation process of floor heating was hidden. Early floor heating companies put a lot of effort into recommendation introduction, feasibility analysis, communication design, model room demonstration, project implementation, etc. . Floor heating projects are increasingly recognized by society with the recommendations of designers, the active selection of construction units, and the impact of engineering examples. In the process of promoting the application of floor heating, floor heating companies have gradually grown and formed a scale. In 2001, there was only a professional plumbing market in the Northeast market, and some special pipes for floor heating could be seen sporadically. By 2005, at least 80% of urban residents knew about floor heating. Consumer demand drove the rapid increase in the proportion of urban buildings, especially commercial and residential buildings, using floor heating. In 2005, floor heating accounted for approximately 30% of the total market share. Above, this proportion continues to grow.

There is broad room for development of floor heating

This heating method has been recognized as the most comfortable heating method as early as the 1930s. It has been used in many countries in Europe, North America, and Asia, and its application is very wide. In 1994, it accounted for more than 50% of the heating market in Germany, Japan, and South Korea. However, in my country, the paved area of ??floor heating is now less than 10%, and it has Huge room for development

Conclusion: In summary, the initial investment of the floor heating system is at a medium level among various heating methods, but because of its good energy saving and service life equivalent to the life of the building , is an investment with a high return (the benefits of this investment in family health and quality of life cannot be accurately analyzed here.

The advantages of electric floor heating and other floor heating

1. Electric heating is a new heating method in my country after 2000. From indirect heating with far-infrared carbon heating panels and geothermal cables to various direct electric heating products, electric heater products have complemented each other in the heating industry in recent years.

2. The biggest advantage of electric floor heating is precise control. No matter how the outdoor temperature changes, no matter how the heating cable fluctuates, due to the use of a very precise electronic thermostat, the temperature of the ground and the air in the room are controlled. The temperature is 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, so it is easier to separate rooms. Time-sharing control

3. The development of electric floor heating is more about its flexibility and intelligence, which has attracted many consumer groups with strong acceptance and awareness.

4. The current situation of my country's electric floor heating industry. It is in the stage of large-scale development. This is the result of the efforts of colleagues in heating cable electric floor heating. Of course, this is also due to the heating advantages of electric floor heating itself, which has driven the development of electric floor heating and gradually eliminated the failure of ceiling heating due to printed ink. The extremely negative impact caused to government authorities, developers, and users due to their application status.

5. In northern China, due to the premise and history of centralized heating, the urban heat pipe network has already been built. It would be a pity to abandon it, and the transformation into electric heating also increases the burden of circuit capacity. It is unrealistic in a short time. As a heating supplement for buildings, office buildings and factories in the north that do not have urban thermal pipe networks, electric floor heating reduces the initial investment cost of urban pipes and balances the seasonal differences in electricity. This is the same situation in the south. Electricity consumption in the south is at its peak in summer, so circuits are designed according to the maximum load. In winter, there is indeed a lot of room for surplus electricity. The application of electric heating balances the seasonal differences in electricity use. , which has brought benefits to the stability of the country and society, and also brought 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 in energy. Electric floor heating has not entered the Chinese market for a long time, and due to the power shortage a few years ago, many people have many misunderstandings about it. With everyone's new understanding of electric heating (society, users, and merchants*** Win) The development of electric heating will surely reach new heights.

With the stability of electric energy and the expansion of peak and valley electricity prices, the advantages of electric floor heating continue to be highlighted.

7. The price of electricity: It is currently the most stable energy price. In the past 30 years, the price of electricity has increased 3-4 times, while the prices of natural gas and oil have increased 15-20 times. In terms of year-on-year economic development, the price of electricity is stable with a downward trend, while the price uncertainty and upward trend of other energy sources are relatively obvious. The history of foreign developed countries also proves this.

8. The electric floor heating system converts electrical energy directly into heat energy without using water, saving precious water resources. It solves a series of land occupation problems such as building boiler rooms, coal storage, ash piles, and pipe network setup, which is beneficial to urban planning. Moreover, the system is completely waterproof, and the joints are also waterproofed, making the entire system resistant to moisture. The electric floor heating system has a service life of more than 50 years, requires almost no maintenance, and has no headaches such as running, leaking, leaking, or freezing and cracking of the radiator.

9. In the northern region, among the buildings with floor heating systems, electric floor heating systems account for 5% to 10%.

10. The advantages of electric floor heating are obvious: from the perspective of energy conservation and emission reduction, electric energy is the cleanest energy and 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.

11. At the market level, since the electric floor heating market has not really boomed yet, competition does not appear to be very fierce, at least not as fierce as the water floor heating market. However, as the electric floor heating market gradually matures, the market prospects are broad.

12. Combining several points to promote the development of electric heating,

First, it is the superior comfort and accurate temperature control of each room (one temperature control for each room)

p>

Second, it is the controllability of the system that meets individual needs (more intelligent control, including future integration with smart homes, will lead the new trend of heating)

Three. It has a long life, no maintenance, and is safer and more reliable than water heating

Four. It is the cost advantage of investment and use (will become more and more obvious)

7. Pay attention to the 7 major issues that make Floor heating is safer

1). Try to use marble, floor tiles or floor combinations. If you choose wooden flooring, you can only choose composite flooring, not solid wood flooring. The thermal stability of wooden floors should be good and the moisture content should be low, so that the floor is not easily deformed after being heated; the size of the floor should be thin rather than thick, narrow rather than wide, in order to meet the requirements of resistance to deformation and conduction; the cushion under the floor should not be too thick. To facilitate heat exchange and conduction. Be sure to choose a floor that releases a small amount of harmful substances such as formaldehyde to prevent the floor from releasing more pollutants due to baking and endangering your health.

2). Try not to use large-area decorations (such as carpets, etc.) on the floor. Do not place legless furniture to avoid reducing the effective heat dissipation area and weakening the thermal effect due to hot air flow.

3). Do not place ordinary foam and plastic products on the floor. Because these items have poor thermal conductivity, they can easily cause heat accumulation and produce harmful gases under the action of long-term high temperatures, endangering the health of residents.

4). Turn on the floor heating system and heat it up slowly. Don't be too hasty, it's best to raise the temperature by about 1°C in an hour. Keep the floor clean and dry before heating to prevent the floor from cracking and twisting due to rapid heating.

5). Do not smash, knock on the ground or pull any sharp objects on the ground. The floor heating pipes laid under the ground are only about 3-4cm away from the floor. If you are not careful, it is easy to damage the floor heating pipes.

6). After the floor paving is completed, it is best to carry out environmental protection acceptance. Since the floor used in the floor heating system is a composite floor, it itself has a formaldehyde release problem. When it is used as a geothermal floor, after heating, the release of formaldehyde is even more aggravated. Therefore, after the geothermal heating floor is installed, it must be inspected for environmental protection to ensure that the amount of free formaldehyde released reaches the standard. Don’t buy cheap goods that are not environmentally friendly at a high price, otherwise there will be endless troubles!

7). Choose professional brands and products with excellent performance. Choose professional and powerful regular companies, and don’t look for small manufacturers and mobile vendors for cheap.

The floor heating industry has a saying of "three parts product, seven parts installation". Floor heating is a systematic project. From scheme design, product selection, construction and installation to after-sales service, it requires professional personnel to design and operate. If a certain If there is a problem in the link, the maintenance will be very difficult, the project will be arduous and complex, and it will even affect the normal use of the entire heating system, or greatly reduce the service life of the entire system. Not only that, it will also lay the foundation for increasing the system in later use. energy consumption and increased usage costs.
