However, disadvantages of the coal stoves and boilers comprise complex structure, huge volume, inconvenient adjustment of temperature, high power consumption and high pollution. As for the electric heaters and the air-conditioners, although they are convenient for temperature adjustment, low heat efficiency, high electricity consumption, small heat radiating area, occupation of limited indoor space are non-neglectable problems to be solved, moreover, many people feel uncomfortable since heat is provided via air convection.
In view of the above problems, China patent number 01248023.1 disclosed an infrared electrothermal floor comprising a plurality of calcium silicate cement guard plate and a carbon fiber infrared heat component disposed therebetween. This kind of floor realizes convenient adjustment of temperature, low power consumption and environmental protection, needs no fuel, saves indoor space, and is capable of supplying heat from a sole of a foot to the indoor space.
However, there are some problems with the above-mentioned floor: firstly, the floor is laid along with electric wire to facilitate integral forming, which causes great difficulty in construction and low efficiency, moreover, once the floor is damaged, it is difficult to fix and maintain, and dangerous electric leakage often takes place. Secondly, the carbon fiber infrared heat component is not efficiently utilized since it is embedded under the bottom of the calcium silicate cement guard plate, which severely affects penetrability of infrared ray, and leads to attenuation in thermal infrared radiation and loss of health functions. Thirdly, the floor is globally electrified, and it is impossible to flexibly implement local control of electricity as required, which causes unnecessary heat loss and influences energy-saving effect. Fourthly, the floor is disposable, once failure occurs, the floor as a whole will be damaged, which causes high using cost and environmental pollution. Fifthly, a top of the floor is only a cement guard plate, and a decoration layer needs to be laid on the bottom thereof, which increases a thickness of the floor and brings about extra burden to a user. Finally, due to attenuation in thermal infrared radiation and slow heat conduction, temperature rise of the floor is very slow and time-consuming, which decreases heat efficiency and influences heating effect.

Advantages of the invention are as follows:
Comfortable Heating Supply
The invention implements low-power and large-area heating supply in a manner of low-temperature radiation instead of air heating, and prevents drying and dust caused by convective heating supply. Heat radiates and dissipates from the ground and acts on a sole and a body of a user, and makes the user feel comfortable and relaxed. A mechanism of the low-temperature radiation is to make human body and indoor objects absorb energy first, and temperature thereof will rise, and then to make them radiate energy, and indoor temperature will uniformly rise. In this situation, actual temperature of human body is higher than air temperature, and thus the user may feel warm and comfortable. Moreover, all rooms are equipped with independent temperature controllers, users are capable of adjusting indoor temperature as required, and thus personalized requirement of the users are realized.
Healthy Heating Supply
In a power-on state, the floor of the invention generates far-infrared light wave with a wavelength centralized between 6 to 16 μm, so as to cause human deep cells to moderately resonate. If a user stays in this environment for a long period of time, his human microcirculation will be improved, metabolism will be promoted, cell vitality will be strengthened and nervous and endocrine systems will be adjusted. Moreover, the invention is also capable of promoting blood flow to smooth meridians and collaterals and improving human immunity.
Safe Heating Supply
The floor of the invention uses materials with good insulation characteristics, a surface resistance and a volume resistance of the floor are greater than 1 MΩ, and electrical breakdown strength thereof is greater than 500V, which make the floor very safe and reliable. Even if electric leakage occurs in use, there will be no electric shock accident.
Environment-Protection Heating Supply
The floor of the invention does not generate noise during operation. By using electricity as a clean energy, air pollution caused by traditional boilers is prevented. By way of electron impact and friction heat, high light or electromagnetic pollution is not generated.
Economic and Energy Saving
Since an electric heat conversion rate of the floor of the invention is above 99% and heating materials are close to the surface of the floor, heat may be adequately dissipated to a room. Average power consumption of the floor is 15-25 W/m2 (architectural area). By way of an intelligent temperature controller, the floor is capable of switching on or off heating at any time in divided periods or rooms, or common movable raised floors may be used in certain unnecessary places, thus operation cost will be significantly reduced.
Convenient Installation
The floor of the invention is easy and convenient for installation. Since heating materials are integrated with the floor, heating and decoration effects are reached after construction, and thus cumbersome processes caused by separated construction of heating resources and floorings are eliminated. An installation process of the floor of the invention is the same as that of a common movable raised floor except for connection of electric appliances and wires.
Fast Heating
2-3 minutes after being powered on, the floor begins heating and heat is quickly dissipated into a room. In cold weather, when people go home, they do not need to wait and will feel warm soon.
Space Saving and Reduced Construction Cost
The floor of the invention integrates a heating function with a decoration function and traditional flues and radiators are no longer needed, which increases usable are of a room, makes the room easy for decoration and reduces cost spent on decoration. Meanwhile, since no heating facility (such as a boiler or a pipe) is used, a storey height of a building can be decreased by 5-6 cm, and thus construction cost is correspondingly reduced.
