Assembled in the UK, with over 70,000 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. It's 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.

By turning the convected heat through 90 degrees so that it is projected out into rooms at waist height rather than getting trapped behind curtains or stuck under protruding internal window ledges, the Radfan Classic accelerates room warm up by re-directing the warm air instead of allowing it to simply rise to the ceiling and then gradually make its way down.

There are now simply 2 model options in terms of length and number of fans. The Classic Short to suit shorter radiators, or the Classic Medium for longer radiators. Multiple units can be mounted on very long radiators.


The Extra Medium is a variant of the Classic Medium, offering all the benefits of the Classic Medium for winter use plus the additional feature of air circulation during warm summer days and nights when the air is still and sticky.

Radfan requires an available UK power socket situated no further than 3 metres from the centre of the radiator. Please note that the fans will not function until the unit senses warm air from the radiator for a few minutes, this prevents energy usage unless Radfan is sure the radiator is on and exceeding 30 degrees C.

In our Proven Energy Savings section you will see that Radfan has been extensively trialled and tested in labs and real world homes to make sure that the Radfan helps customers feel warmer and reduces their energy bills.


On our Instructions page you will find how easy it is for customers to set up the Radfan on their radiators and plug into a standard UK power socket - please note that this product is only technically suitable for use in the UK and should not be sold for use outside of the UK.
