Problems solved by technology

In addition, as the main measure to prevent the heating coil from dissipating heat downward, if the insulation layer is removed, it will be more difficult to calculate the heat load of the room
However, using polystyrene board as a thermal insulation layer has unstable physical and chemical properties, and it emits harmful gas itself.
Aluminum foil is used as a reflective film, and its combination with the heat insulating layer is not reliable
