Electric heaters use electrical energy as the main energy source, and use resistance heating, induction heating, arc heating, electron beam heating, infrared heating, and medium heating to heat the human body through direct contact, warm air convection, and far infrared radiation.

Main functions of electric heater

1. "Intelligent temperature control function" It consists of two parts, one is the temperature sensing unit and the other is the control unit. It senses the indoor temperature through its own temperature-sensing unit, and then makes the operation of turning on and off intelligently through the control unit, without human control. You only need to set the temperature value. In addition to the convenience of this feature, it can also effectively save power.

2. "Negative ion function" The ion particles in the air are divided into positive ions and negative ions. Normal bacteria, dust, and toxic and harmful gases all carry positive ions. After adding the negative ion function, a large amount of negative ions are produced, which are actively combined with positive ions carrying materials such as bacteria, thereby effectively reducing indoor bacteria, toxic and harmful gases, and purifying indoor air.

3. "Humidification function" Because the indoor temperature rises after using heating, a certain amount of water will be lost, so the humidification function can effectively make up for the moisture required by the human body. Air humidity is also an important indicator of environmental comfort.

4. "Reservation and timer function" reservation is to turn on automatically according to the specified time, and timing is to turn off according to the specified time.

5. "Remote control function" Generally speaking, those with remote control function have intelligent temperature control function.

Type of heater

PTC heater

PTC is an abbreviation for a ceramic electric heating element. It uses a fan to blow air through the PTC electric heating element to force convection, which is the main heat exchange method.

The internal thermostat is installed, and when the tuyere is blocked by the fan, it can power off by itself. Some also have the function of automatic power off when tilting to the ground. That is, when the heater is tilted or overturned, it can cut off the power supply by itself. The output power of the PTC heater is 800-1200 watts, and the temperature can be adjusted at will.

Advantages: Soft air supply during work, fast temperature rise, automatic thermostat function, PTC components generally have waterproof function, small size, can be used in the bathroom.

Disadvantages: low power, can only be used in a small range. If you blow on the same place for a long time, the human skin will feel uncomfortable. Moreover, if it is not cleaned in time for a long time, the bacteria on the heater will be accelerated into the air and become a health risk. In addition, the power of the heater is generally relatively small, and the noise when turning on the power is also a headache.
