Well, there is the possibility of using the stock heater
boxes but adding some kind of recirculating system to "reuse"
the interior air instead of constantly forcing in new air.  
There are kits to do this (I've seen ads in the VW rags) and
people have noticed that the fans used in these kits are
available at much lower cost in marine stores (I think
"in line bilge fan" rings a bell).  Bob Hoover has a 
sermon on this topic; according to at least one correspondent
of his from Norway, the system works.

I'm thinking about this for my '62, and would like comments
from anyone else about what they think. . . . .
