Assembled in the UK, with over 80,000 units sold since its introduction in 2013, Radfan is the leading radiator mounted product designed to improve the flow of convected heat from standard UK domestic radiators into and around rooms more effectively.

 Its magnetic mounting system enables the product to be easily installed by customers (30 second set-up) and it fits both single and double panel radiators, with or without grills fitted, which currently make up the majority of radiators used in UK homes.

With current energy cost rises, independent tests show correct Radfan usage can save the average household up to £700 year year.

Radiator Fitment Information

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.

The magnetic attachment system allows fitting to the top of a wide range of steel panel radiators.

*Although the Radfan product does function on all types of water filled steel panel radiators (doesn’t fit on single panel versions if they do not have convection fins) the overall performance will not feel the same for single panel radiator with fins as double radiators (with or without fins).

The performance is also dependent on other factors in each individual application, such as the hot water temperature setting on the boiler, and flow rates around the radiators.*

Radfan does not fit single panel radiators which do not have fins (convectors)

Single panel, single convector

Double panel, single convector

Double panel, double convector

Works with and without grill top
