As the original poster that was my problem too. I only have a 60A
alternator and could not afford the heat from a typical fan heater. I
need that alternator for important things - like keep flying.

Because a (for example) 80 amp alternator puts out only a nominal 960
watts at 12v. Even if you could use all that for heating -- which of
course you can't -- it would be a pretty anemic heater.
