For smart people, how to save money is the "hard truth." Which is more cost-effective to install heating and air-conditioning? We calculated an account for you:
Heating room area of ​​about 100 square meters, if you want to install a set of current mainstream gas boiler as heating equipment, the total price = material costs (100-300 yuan / square meter, divided into two categories of domestic and imported) + boiler costs (6000 yuan "3 million yuan, import-oriented, Japan and South Korea goods are relatively affordable, European goods quality is excellent), the initial installation costs about between 15,000 - 50,000 yuan; the same area almost buy three air conditioners, the price is still more than Warmer and cheaper. However, the normal service life of floor heating is 50 years, which is much better than air conditioning.
In use, taking a room of 10 square meters as an example, according to the current electric floor heating power of 120 watts/square, the total power of the room is 1200 watts, which is open 24 hours, and the actual power consumption time is about 6-9 hours every day. Electricity is about 7.2-10.8 degrees; while the air conditioner's power is 850-1500 watts, which is opened 12 hours a day. The actual power consumption time is about 9.5 hours, and the power consumption is about 8-14 degrees. Obviously, if the air conditioner is turned on for a long time, the electricity cost of the air conditioner will be higher than the floor heating.
Installed floor heating
Undoubtedly, warmth is a shining element in this winter's fashion personalized home improvement. However, in fact, there are a lot of exquisite installation of floor heating.
The floor height can not be too low, but also no heat source trouble
The floor heating system takes up about 5-6 cm of floor height, which has a great impact on the lower-storey houses. However, if you originally plan to install wooden floors, it will only be 2-3 cm higher than your imagination.
In addition, if you want to install a warm source of heat, you must first obtain the consent of the developer or property company. As the floor heating pipe is longer than the radiator and the water resistance is large, it will have a slight impact on the heating effect of the entire building. The property may oppose. The best way is to negotiate with the developer before buying a house.
In general, as long as the height of your home is not too low and you are not in trouble with the heat source, it is suitable for floor heating.
Electric heating below 100 square meters, water heating above 100 square meters
The floor heating is divided into plumbing and heating by media. According to industry insiders, the choice of 100m2 or less is more electric heating, and more than 100m2 is selected to install central plumbing.
Plumbing consists of gas stoves, water collectors, and buried pipes. Low-temperature hot water is used as the heat medium. The floor is heated by pipes embedded in the floor. At the same time, multiple hot water supply points (such as showers, bathtubs, and hand-washing) are connected. Taiwan, kitchens, and washing machines) provide a comprehensive solution to the hot water supply for the entire family, which is an ideal heating method.
What if it has been renovated and does not require secondary decoration? Designers recommend plumbing floors. “The floor is only 1.2cm thick, and even if it is laid directly on the original floor, it will not affect the floor height. With a fast heating, it will be able to heat in half an hour. Afterwards, if you move, do not warm it up. Take the floor and take it away. Yes."
In terms of paving the floor, Xiao Song suggested that people need to walk around frequently to avoid wasting. "But this is because it is imported ultra-thin, so the price will be slightly higher, an average of 300 yuan / square meter."
To warm the floor, you have to know these
1, not all floors can be floor heating
The definition of "floor heating" should be applied to the wooden flooring laid by the ground floor radiant heating system and transfer heat through the floor facing the room. There are many names on the market, what “heating floorâ€, “floor heatingâ€, “heat-resistant floorâ€, “geothermy floorâ€, “dedicated geothermal floor†and so on, in fact, can not just listen to the name, and the applicable floor heating needs 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, not the thicker the floor more insulation
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 floor thickness is too thick, it is not conducive to the conduction of heat through the floor to the board surface, which 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.
3, geothermal heating floor specifications should not be 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 and contraction of the wet swell, not to mention in the case of heating the floor, because the water is distributed faster, even more Prone to floor separation.
4, placing legless furniture or carpet on the floor will destroy the floor cooling surface
These furniture are often floor-to-ceiling furniture that has 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 dissipated due to heat and excessive concentration. Causes the floor to be heated unevenly, causing the floor here to be deformed.
