Radfan Classic Small – Radiator Booster


Radfan Classic Small – Radiator Booster


The Classic Small contains 2 fans and is designed to sit on top of shorter radiators less than 1 metre in length

Fits all

As the smallest member of the Radfan family, the Radfan Classic Small is perfect for radiators small and large. The magnets secure it on to both single and double panel radiators.


Thanks to its size and magnetic fixings the Radfan Classic Small can easily be moved from room to room. For that lazy afternoon in your reading corner or the occasional day in the home office you can bring the warmth with you.

Re-direct the heat into the room

For radiators under windows the Radfan Classic Small reduces heat lost through the window by 35%, keep the warmth in your home and stop warming up the great outdoors.

Forget about it

The built in thermostat means the Radfan Classic Small runs itself and won’t bother you at all. When the radiator is hot, your Radfan Classic Small turns itself on.

The Radfan has been designed from the ground up to be a simple self install product. It secures by magnets to the top of your radiator and installs in less than 30 seconds – it’s just like installing a reading lamp.

​Please note that Radfans must not be placed on any heating device other than a water-filled steel-panel radiator. Radfans are not recommended for use with electric radiators/storage heaters or other types of radiator due to higher surface temperatures and varying designs, making a secure fit and safe operation impossible to guarantee.
