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. Radfan has been extensively trialed and tested in labs and real world homes to make sure that the Radfan helps you feel warmer and reduce your energy bill.
Field Trials - 9 Housing Associations, 99 Homes
Testing devices in real homes is vital and so Radfan teamed up with DECC and 9 housing associations to better understand how people respond to the Radfan. Each home lived with the Radfan for 2 months and was asked a set of questions before and after the trial.
Pre Radfan Installation:
43%noted that can't afford their energy bill 47%do not feel warm enough at home 42%use secondary heating Post-Radfan Installation:86% felt increase in thermal comfort 45% reduced heating use 53% reduced use of secondary heating Average Expected Energy Savings:1875 kWh reduction in heating energy use £75 saved per year
The Radfan works best in homes that are already insulated with 2 or 3 bedrooms. One of the key takeaways from participants is that they like the effect of feeling warm air coming from the unit. People love the Radfan as they not only feel an increase in their comfort but it also gives them an extra layer of control to help keep warm and tackle ever increasing fuel bills.
Lab Testing - Salford University Energy House
The Energy House at Salford University is a fully instrumented house built in an environmental chamber used by the likes of Saint Goban and B&Q to test energy-saving product.
Testing: Radfan installed a Radfan in the living room of the Energy House and monitored the home, with and with out the Radfan running, over two 48 hour periods. The house's heating was set to run 24 hours a day, with the water set to 82°C, thermostat set to 21°C and the curtains opened at 9 AM and closed at 4 PM.
Results:1.02°C warmer at sofa height. 35% reduction in heat lost through the window. 25% reduction in thermal stratification Annual Energy Saving: 720 kWh reduction in heating energy use. £31 saved per year Total Expected Energy Savings: 2595 kWh reduction in heating energy use. £106 saved per year.
Important - Radfan Operation .
Radfan is not designed to start immediately after being plugged in and switched on (excluding the Radfan Extra model with switch set on summer position). The fans are thermostatically controlled and not run on the radiator straight out of the box.
Radfan needs to be positioned on the radiator with the heating system turned on and radiator up to temperature , the fans will only start a few minutes after sensing the warmth coming off your radiator. When your heating switches off and radiators cool below 30 degrees C the fans will automatically switch off so as not to blow cooler air.
Radfan is not a silent product. The fan speed (noise) is designed as the optimum solution between airflow and noise level.
Usage For indoor use on a water filled radiator to help recirculate heat within the room. Please note that the Radiator Radfan is only suitable for water filled radiators and not oil filled radiators, electric storage radiators or electric convection radiator.

the Radfan Classic uses 2W (about £2/year to run)
the Radfan Long uses 4W (about £4/year to run)

Q What types of radiator will the Radfan fit on?
A The Radfan will fit on all standard panel central heating radiators and will self support on double and single panel radiators.
Q If I don't like my Radfan can I return it?
A Absolutely, we want everyone to be happy with their Radfan so if you don't like it for any reason you can return it for a full refund within 30 days of purchase. However please see operation information on this page showing how the radfan works.
Q Will the Radfan work on electric heaters/radiators or night storage heaters?
A Sadly not, we're sorry to say that with the huge range of electric radiators and their range of temperatures it wasn't possible to design the Radfan to accommodate these.
Q Will it work inside a radiator cabinet?
A Yes! Many of our customers have used the Radfan in radiator cabinets and have seen a big improvement. So long as there is more than 8cm from the top of the radiator and the roof of the cabinet it will all fit fine.
