The shell structure of the panel heater is divided into air outlets, air inlets, front and rear panels, left and right columns etc. After power on, the air around the heating body is heated up and flows out from the air outlet, while the surrounding cold air is sucked and supplemented from the air inlet due to negative pressure. Such repeated cycles can increase the indoor temperature to the set temperature required for life; when the air inlet or outlet is covered, blocked or the ambient temperature is too high, the temperature control element will automatically disconnect the heating body power. Panel heaters generally have an output power of about 800-2000W. The power can also be adjusted by increasing or decreasing the heating body power, turning on the number of heating body units, and adjusting the heating body working voltage. The panel heater has higher safety performance and quiet operation, but the disadvantage is that the temperature rises slowly.

Fan heaters is using electric heating wires or PTC ceramics as heating materials are mainly the more traditional heaters in the market. The heating element is an electric heating wire or PTC, and a fan is used to blow out the heat generated by the heating element. Then there is another type of heater products in the market: The appearance of the electric fan is heated by a heating wire wound on a ceramic insulating base, and the heat energy is diffused to the room by the reflective surface. Like an electric fan, this heater can automatically rotate its angle to heat the entire room, and is suitable for use in small rooms less than 8 square meters. This kind of heater, like an electric fan, can automatically rotate its angle to heat the entire room. It is suitable for use in small rooms below 8 square meters. The disadvantage is that the temperature drops quickly after shutdown, the applicable area is small, and oxygen is consumed, and the heating wire is prone to breakage after long-term use.
