That's why I'm so keen to learn more about Phil's upgrade.
Did you see the info I put on my other post about the heater?
I did mate. I am currently pondering if I can do something similar but as I have the later heater matrix on the top of the scuttle I think I'm going to have a different arrangement. If I can get a squirrel cage fan in the space available and make up a different distribution arrangement I might be able to improve matters.
