I guess I'll spell it out in more detail then:
1. There is nothing, repeat, NOTHING restrictive to the exhaust flow in a VW/Corvair/aircraft exchanger system.
2. The air coming out of a VW/Corvair/aircraft heater in proper working order is so hot you can't even hold your hand next to the outlet. Efficient or not, it is plenty hot enough to do the job.
P.S. I'm not saying the air/air systems are superior. There is nothing more pathetic than the defroster on a Microbus.
