What kind of heating method is good and saves electricity? Know almost

The air heater uses the fan in the heater to suck in indoor cold air from the air inlet, then flows through the electric heating element to raise its temperature, and then sends out hot air from the air outlet to achieve the purpose of heating. The main features are that the power can be automatically adjusted, the temperature is self-limited, the heating speed is faster, and the room temperature is more uniform and comfortable. Its disadvantages are high energy consumption and noise caused by the rotation of the fan.

2. Hot heater

The cavity of the heater is filled with heat transfer oil, and there are large fins outside. When the power supply is turned on, the heat transfer oil around the built-in electric heating element is heated, and then the heat is radiated to the space through the fins to achieve the purpose of heating. It has infrared radiation and convection, so it can be said to be a composite heater. It is characterized by no need to replace the heat transfer oil, long service life and the advantages of safety, hygiene and dust-free. Disadvantages are high energy consumption, large thermal inertia and slow temperature rise.

3. Electrothermal film heater

There are mainly two kinds of high-temperature electrothermal film heaters and low-temperature electrothermal film heaters, which belong to radiation heaters. This product uses electrothermal film as heating material, which has developed rapidly in recent years. It has good water tightness, flexibility, folding resistance, corrosion resistance and aging resistance. After the electric heating film is electrified, the electric energy is converted into heat energy, and the heat energy mainly spreads by radiation.
