Radiators are REALLY

badly named

Ever wonder why your feet are cold?

Most of the heat leaving your radiator is convected and so gets trapped at the ceiling or is lost through your window leaving you feeling cold.

Radfan's unique designs increase the warm air flow and puts the warmth where you want it most. Making you warmer for less.

Before the radfan is installed the heat is trapped at the ceiling

Frequently Asked Questions

Q   What size is the Radfan?

A   Take a look at our comparison chart to see the dimensions of all three Radfans.

Q   What type of radiator will the Radfan work with?

A   The Radfan has been designed to work with steel panel, water filled radiators. Sadly it's not suitable for victorian style cast iron radiators.

Q   How is the Radfan powered?

A   The Radfan is powered from a 12V power supply that comes in the box. The Radfans are very low power:

  • the Radfan Classic uses 2W (about £2/year to run)
  • the Radfan Long uses 4W (about £4/year to run)
  • the Radfan MAX uses 6W (about £6/year to run)

Q   How long is the power lead?

A   The power lead is 3 metres long and is in 2 halves. The 1.5 metres connected to the Radfan is heat protected to live happily behind your radiator.

Q   How noisy is the Radfan?

A   The Radfan is a lot quieter than an electric fan heater and if you have the TV or Radio on then you can't hear it.

Q   How many Radfans do I need?

A   The Radfan is designed to be improve the comfort of the room it is fitted in. Most of our customers start with a Radfan Long for their living room and then come back and buy the most suitable home pack for the other rooms in their home.

Q   Won't the heat affect the Radfan?

A   We made the Radfan out of the same ABS plastic that radiator control valves are made from and so it is more than happy at the temperature of a radiator.

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   Will the Radfan work in Europe or America?

A   Yes, the power supply that comes with the Radfan is suitable for world use. All you need to do is make sure the radiator you want to fit it to is a steel panel, water filled type and that you have a plug adapter suitable to convert the UK 3-pin plug socket to your country's socket type.

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.

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.
