Heaters Are Classified Into Three Categories According To Their Shape And Structure:

(1) Horizontal-blowing fan heater: Indoor air is drawn in from one side, heated by a heat exchanger, and then discharged horizontally. The jet has a certain range, ensuring thorough mixing of air in the heated area and uniform temperature.

(2) Top-blowing fan heater: An axial fan is placed below the unit. Air enters from the side of the heater, is heated by a vertical air heat exchanger, and then discharged downwards. To maximize the downward jet surface area, guide vanes for diffusion are installed at the fan outlet.

(3) Floor-standing fan heater: This type of unit has a large air volume and a long range for delivering hot air, capable of heating a large area. It is noisy during operation. Suitable for heating factory buildings.
