Besides air conditioning, the electric fan is an essential cooling device that is always operated at full capacity in the family during hot summer days. There are many types of electric fans, including pedestal fans, ceiling fans, and wall-mounted fans. Among them, pedestal fans and ceiling fans are the most popular.
Many people are confused about whether to use a pedestal fan or a ceiling fan, which type of fan will save more electricity and provide cooler air.
The energy-saving efficiency of ceiling fans and pedestal fans depends on their power.
This is a characteristic quantity for the operating speed of electrical devices and is determined by the work done per unit time. The higher the power, the greater the energy consumption, and vice versa, the lower the power, the less energy the device consumes.
So let’s find out how the power of ceiling fans and pedestal fans differs!
1. Ceiling Fans
Ceiling fans are cooling devices mounted on the ceiling of a house, usually without a fan cage, and when the fan blades rotate, they create air for the entire space. Nowadays, with the development of advanced technology, some ceiling fans are designed without blades.

Most traditional ceiling fans usually use AC motor technology, and the rated power is usually in the range of 70W – 95W. However, there are also new types of ceiling fans equipped with DC motor technology that save electricity, with a power rating of only 40W – 55W.
From these indices, it can be seen that ceiling fans consume a relatively small amount of electricity. According to some measurements, a ceiling fan will consume 1 KWh of electricity in about 12 – 14 hours of operation, depending on the motor type. This figure is equivalent to turning on 2 fluorescent lamps.
2. Pedestal Fans
Unlike ceiling fans, pedestal fans are designed in a tree-like shape and can stand independently on the floor. The structure of the fan usually includes fan blades for cooling, a fan cage for blade protection, and a control system.
In addition, pedestal fans have the advantage of being able to adjust the direction of the wind. Users can adjust the fan wind to one specific point or also circulate the air around the room by turning on the oscillation mode.
Pedestal fans commonly used in daily life have a power rating of about 45W – 75W. Within about 16 or 17 hours, they will consume 1KWh of electricity.
Which one to choose: Ceiling fan or pedestal fan?
From the power figures, it can be seen that ceiling fans consume more electrical energy than pedestal fans when operating. However, it doesn’t mean that we should always choose a pedestal fan for our family because of that. The choice between a pedestal fan and a ceiling fan should be based on the area and the number of people in the space.
With the usual blade size of about 1.2m – 1.5m, ceiling fans are suitable for large, spacious spaces. The fan will provide strong and cool air over a wide area, effectively cooling the entire space.
On the other hand, pedestal fans are more suitable for smaller spaces. Although they have the ability to oscillate and circulate air, the air diffusion range of pedestal fans is quite small. The advantage of this type of device is to focus on cooling a fixed position and is suitable for spaces with fewer people.

Therefore, in a large space with many people, it is best to consider using a ceiling fan with a large blade span. If you use pedestal fans in such spaces, you will have to use more devices, which will consume more electricity.
Choosing the right type of fan that meets your needs and purposes will not only help save energy but also optimize the cooling function of the device. So, consider choosing the right ceiling fan or pedestal fan that is most suitable for your family!
