Supply Nanning floor heating installation
Installing floor heating quietly rises in Yongcheng
"Before decoration, I had no experience of spending winter in the south, so when I first came to Nanning to decorate my new house, I didn't think it was necessary to install floor heating, because the temperature in Nanning rarely drops below 0 ℃, and there is room for heating air conditioner 。” Mr. Qu, who lives in a community on Zhuxi Avenue in Nanning, is a native of the Northeast. In 2009, due to job transfer, he settled down in Nanning.
"Last year, my mother retired and planned to stay in Nanning for a long time, but she was afraid of the cold because there was no floor heating at home last winter. This winter, the old man planned to return to the northeast, rather than stay in Nanning." Therefore, Mr. Qu is busy shopping for floor heating products recently, hoping to keep his mother in Nanning for the winter.
Before the snow disaster in 2008, Mr. Mao, a native of Henan Province, took advantage of the renovation of his villa and installed floor heating facilities at home. "I haven't suffered much in winter for several consecutive years. In Nanning, it's unbearable to be around 5 ℃," he said.
A floor heating equipment company told reporters:“ Nanning The market was originally a blank spot in the floor heating industry. In 2006, when the market started, it was basically installed by northerners. They are Nanning I can't stand the cold. I need to install floor heating. In recent years, the ground heating market has slowly warmed up, especially after the snow disaster. In the past two years, I have never used floor heating Nanning People also came to inquire about it, and they thought it was good. Word of mouth can help business get better. "
"Our company has been established for three years, and home furnishing customers have installed more than 100 households." Engaged in floor heating equipment pin Li XX, the seller, said that the floor heating technology is relatively mature, the price is not high, and more and more city in Guangxi Family favor.
Air conditioning heating, less comfortable than floor heating
Because she often watches Korean dramas, Ms. Wen, a citizen, envies that Koreans can not only sit on the ground in winter, but also sleep at night Wood floor On. She said, "In the winter of 2010, when I traveled to South Korea, the agricultural production system would experience floor heating. Because South Korea has floor heating, and according to their living habits, it is 24-hour heating after winter, so no matter when, floor It's warm. " Last September, she decided to add floor heating to the house, but she didn't want to make a big fight. After comparing several installation methods of floor heating, self heating floor is selected.
"The comfort that floor heating brings to people in winter is not the same concept as air conditioning." Ms. Wen said that the heating of air conditioning is from top to bottom, always warming up first and then warming up, which is easy to make people feel dry and dizzy. On the contrary, floor heating is floor radiant heating, which heats the feet first, and hot air moves from bottom to top, thus increasing the comfort of the human body. "If economic conditions permit, installing floor heating is a good choice," she suggested.
In fact, heating and air conditioning can coexist. They have their own advantages: floor heating cannot replace the cooling function of air conditioning, and air conditioning cannot replace the comfort of floor heating in heating. In addition, frequent use of air conditioners will make the room very dry, and will breed bacteria and microorganisms, affecting human health. Floor heating is installed. The room in winter is not only moderate in temperature, but also not dry and stuffy. The room installed with floor heating can promote the blood circulation of feet and legs, and can achieve the health effect of "warming feet while keeping cool" advocated by Chinese medicine.
Which floor heating method is suitable for you?
According to reports, according to different heating modes, floor heating can be divided into water floor heating, electric floor heating and carbon crystal floor heating (also known as "self heating floor"). When choosing floor heating, consumers should know their own characteristics in advance according to their own actual conditions, and choose suitable products in combination with their family's daily living habits.
Water floor heating can supply domestic hot water, suitable for large households
[Principle]
Water floor heating is a heating method that uses hot water whose temperature is not higher than 60 ℃ as the heat medium, circulates in the heating pipe buried in the filling layer below the ground, heats the whole floor, and supplies heat to the room through radiation and convection heat transfer from the ground. Most cities with central heating facilities in the north adopt this method.
[Initial installation cost]
Li Jiangang introduced that water ground heating is mainly composed of three parts: the main engine includes hot water sources, usually using heating gas wall mounted furnaces, or small boilers, solar energy and heat pump ； Then the temperature control system; Later is the floor layer. From his experience, people who have large houses such as villas and mid floor buildings or who have full room heating considerations usually choose boilers. The boiler mentioned here is not the large boiler in the factory, but a small boiler similar to the gas water heater. One for each household. Each room can be controlled separately through the water distributor. When decorating, the owner can explain the situation with the decoration company in advance. The load of the rooms that do not live often is lower, and the load of the old people's houses should be higher. In this way, we can determine how to lay the pipelines and how dense they are according to the owner's living habits and bearing range. The reporter made a simple calculation. Based on the 150 square meters of living area, the overall investment in installing floor heating is usually not more than 40000 yuan, and the cost is shared equally, ranging from 200 to 400 yuan per square meter.
Relatively speaking, the installation of water and ground heating is difficult, and the system maintenance and commissioning costs are high. Taking a 100 square meter house as an example, the installation of water and floor heating requires 4 workers to install for 5 days, including two days for pipe laying, two days for boiler installation and one day for commissioning.
[Use Cost]
Generally speaking, the service life of boilers (including gas-fired wall hung boilers) is 12~15 years, and the service life of water diversity collectors is 6~8 years. At least 3 boilers and 6 water diversity collectors need to be replaced within 50 years. The life of the temperature controller is relatively short. Most domestic ones can be used for 3 to 5 years, while imported ones can be used for 8 years. However, the price is relatively cheap. You can replace one with three or five hundred yuan.
In addition, after the water heating system has been operating for 2 to 4 years, more slime, bacteria and scale will accumulate in the pipeline, forming pipeline blockage, leading to increased gas consumption and rising use costs.
[Heating effect]
The preheating time needs more than two hours.
[Suggestion]
"Most cities in the north have central heating. The initial installation cost and use cost are relatively low, which can reflect the advantages of water floor heating. But at present, Nanning has no central heating system, so the advantages are not obvious." Li Jiangang suggested that water floor heating is more suitable for large houses and large families. There are often old people or children at home, and the 24-hour startup cost is more energy-saving than the 24-hour startup of electric floor heating. At the same time, it can also provide 24-hour domestic hot water without the need to purchase water heaters.
