Wired floor heating directly converts electric energy into heat energy, similar to the principle of electric kettle boiling water. This has certain electromagnetic radiation, and any circuit failure will lose its function. There is no problem with the safety of carbon crystal floor heating, that is, there will be thermal attenuation after a long time, and there will be obvious non-hot areas in 3-5 years, which is not cost-effective; The principle of graphene floor heating is that the carbon atoms of graphene form Brownian motion under the action of current, generate heat through friction, and then radiate heat in the form of far infrared, similar to sunbathing. This floor heating does not directly convert electric energy into heat energy. Therefore, there is not only no electromagnetic radiation, but also far-infrared health care function which is very beneficial to human body. But at present, only a few companies in China have the strength to produce this kind of floor heating, such as Papa Bear floor heating.
