With temperatures dropping, many have already turned their heating systems back on. Every winter we expect an increase in energy bills, and the question therefore arises spontaneously: how to reduce these growing costs? A possible answer lies in specific accessories for thermal management, such as radiator fans.
Radiator fans: how do they work?
Often called an exhaust fan, diffuser or heat extractor, a radiator fan is a device that maximizes heating efficiency. Radiators, in fact, generate heat that tends to rise, causing stratification of the air: the hot air is concentrated at the top and the cold air at the bottom, without the heat being exploited to the maximum. By placing the fan directly on the radiator, connected to the electricity supply and with a consumption of only 2 Watts, this device activates automatically at around 30°C, moving the hot air into the room more quickly and uniformly.
Advanced performance and features
The main advantage of the radiator fan lies in its ability to increase the sensation of heat in the room, without the need to raise the set temperature. By moving the hot air, the perceived temperature can be increased by 2-3 degrees, with energy savings of up to 20%. Some models are equipped with brackets to also be placed behind radiators, recovering the heat lost in that area. Larger fans, ideal for large radiators, offer automatic regulation options and, in some cases, a lifespan of up to 40 years.
How to choose and use radiator fans
When choosing fans, it is important to consider the size of the room to be heated: for a room of approximately 12m², one fan is enough, but for larger rooms more will be needed. Each unit moves approximately 30m³ of air per hour, allowing for optimal circulation. Furthermore, up to 20 fans can be connected to a single adapter, simplifying installation even on long radiators.
However, it should be emphasized that these fans are not suitable for high humidity environments, nor for electric and oil radiators.
