Phil,
With the objective of preventing carbon monoxide from within the cabin,
I chose to go with a heater core rather than a heat muff.

Here's what I did.  I fabricated a heater unit around an early vintage
Mustang heater core available from various vintage Mustang suppliers for
about $25.  This is a dual pass core where the lines come out of the
core on one end, 90* to the face of the core. This configuration worked
out well.  I used a 6" equipment/computer box fan ($15 at mpja.com) and
PWM motor speed controller ($15 at mpja.com).  Coolant flow (heat) is
controlled with an inline control valve which I purchased from my local
NAPA dealer.  The housing is made from .032 aluminum sheet.  I haven't
flown as yet, but it appears to work well on the ground.  The whole unit
is very compact.

One more thing, the core should be cushioned to prevent rubbing on the
metal housing.  The vintage Mustang suppliers carry nice molded rubber
end cushions that make this a non-issue.=20

Has anyone found a good auto heater unit that they have used (or would=20
recommend) for their plane?

My dream unit would be complete with heater core, fan with 3 spd=20
resistor, enclosure with 2 or 3 flaps to open/close for heat and=20
defrost; all in a small and light enough unit to fit under the=20
instrument area of my RV-10.  Any suggestions/auto models??
