Radfan2 years and 8 versions

It all starts with a sketch

No name yet, just a concept born out of a problem

Knew that heat wasn’t where people need it

Basic idea to get that warmth where is it needed

1. Cardboard

Simple card version with forward facing fans

Warmed up the room - on to winner?!

2. The same, but different

Same as before but made with plastic

No thought on design but useable and effective

3. Manufacture-able?

Separate sections - 3D printed end caps

No aesthetics yet but practical and buildable

4. All in one Mondeo style

1 single curved part - like the original Ford Mondeo

Limits further product growth and lacks style

5. Very nearly there

Back to separate parts and adding some style

Logo picked up on the fins - too “curvey”

6. Much better

Essentially the same but refined edges and logo

White paint job added this time

7. Made from plastic

First full plastic prototypes - a bit ropey but useable

Used for field trials - learned ALOT with these

8. Grande Finale

Final parts off the production line

Looks great, like it should be on the radiator

9. Future plans

We’ve got big plans for the Radfan but they won’t be ready

this winter, needless to say though, central heating needs to

get smarter
