The quartz tube heater does not need electricity, which is more energy-saving and electricity-saving. The quartz tube will not be heated, and the inside is also heated by electric heating wire. Thunder radiates through quartz tube, and the radiation heat is greater than that without quartz tube.

According to the law of conservation of heat, some heat will be lost in the process of heat transfer. The electromagnetic heater makes the metal object barrel heat itself, so there is no heat loss, so it is more energy-saving.
