Why Graphene Electric Heating Film is More Economical to Use than Heating Cables

As electric heating is promoted in residential heating, people often notice an interesting phenomenon: two households with the same power of heating cables and graphene electric heating films, on the same floor, facing the same direction, having the same area, being middle-floor units with identical insulation conditions, yet their heating electricity bills differ by more than double. Why does this happen? In fact, there are two main reasons for this:
First, there are two forms of heating, line heating and surface heating, which have different efficiency in heating the room.
The second is that the amount of electricity wasted when it is converted into heat is different, that is, the conversion rate of electric heating is different.
Last time we talked about the first difference, today we'll talk about the second difference:
In fact, the same input power, but different output power.
Due to the heating cable generating various visible and invisible light waves when powered, the principle is similar to how electric lights produce ineffective heat when they emit light. Among these visible and invisible light waves, only infrared light waves belong to thermal radiation; the others do not generate thermal radiation. When the Lisheng Shishi Graphene Electric Heating Film is powered, it generates far-infrared light waves in addition to heat, with the total electrical energy converted into heat or far-infrared light waves exceeding 99%. Therefore, under the same input power, the heating efficiency of the heating cable and the graphene electric heating film differs.
Therefore, in order to achieve the same thermal power output, the heating cable needs more input power than the graphene electric heating film, so in the same time, the heating cable consumes more electricity than the graphene electric heating film.
