I just realized its really easy to completely take it apart. Everything is modular, either plugged together or screwed. So modifications are really easy.
[EDIT]
The heating element is actually HOLLOW, the air intake goes through the bottom of the heating element and through holes in the middle of it, right beside the hose connection. It would be technically possible to close those holes, make a hole in the "head", add a metal screen to it and therefore add more of a convection part to it, as you would suck hot air through the bud instead of just heating the bud and moving cold air past it. That would be a rather major mod though.
[EDIT2]
Compared to the BC model this thread is about, the vapours are NOT passed through the "guts" (the lower comparement with the electronics) in this one! However, the air intake goes through that part. Actually, the hole for the power cable is also the air intake.
