How are electricity costs calculated?
The calculation uses the following formula:
A ceiling fan usually consumes significantly less electricity than an air conditioner. However, it is important to note that a ceiling fan does not actively cool the room down. It creates a more pleasant feeling through air movement and can therefore be an economical alternative, especially in bedrooms, living rooms or home offices.
Typical guide values at a glance
| Device | Typical consumption | Suitable for |
|---|---|---|
| DC ceiling fan | approx. 15-35 watts | Bedroom, living room, quiet continuous air circulation |
| Classic fan | approx. 40-75 watts | Short-term air movement |
| Mobile air conditioner | approx. 700-2,000 watts | Active cooling at high room temperatures |
Ceiling fan or air conditioner?
An air conditioner makes sense when a room really needs to be actively cooled down. A ceiling fan, on the other hand, is particularly interesting if you want to create a more pleasant room climate with much lower electricity consumption.
For many living spaces, a quiet ceiling fan is therefore a very good solution - especially when the focus is not maximum cooling, but pleasant air movement, low operating costs and quiet living comfort.
