In summary, due to the adoption of the technical scheme, the invention has the beneficial effects that:
1. the far infrared nanometer microcrystalline glass electric heating piece is adopted to replace a boiler to supply heat, and the heating mode of heat conduction of a heating medium is safer.
2. The far infrared nanometer microcrystalline glass electric heating piece has wider heating area relative to the heat conduction of the coil pipe, and the heating plate can heat up more quickly.
3. The far infrared nanometer microcrystalline glass electric heating piece has less heat loss, heating is carried out inside the heating plate, no loss in the pipeline conveying process exists, the electric-heat conversion rate is high, and resources are fully utilized.
4. The far infrared nanometer microcrystalline glass electric heating pieces have long service life, and the far infrared nanometer microcrystalline glass electric heating pieces are connected in parallel, so that other normal work cannot be influenced even if a certain electric heating plate is damaged.
5. The far infrared nanometer microcrystalline glass electric heating piece is adopted to heat, so that the energy consumption is greatly reduced compared with that of a boiler or an electric heating tube, and the power consumption requirement is reduced.
