Doug,
I’ve attached pictures of the heater
I use which was donated by the 86 RX7 that also donated the engine. In my
RV6A, each cockpit vent tube is tee’d to one side of the heater which is
located under the center of the instrument panel. By operating the gate
valves on the heater sides in combination with opening and closing the normal
eyeball vents, the air distribution is quite controllable. I initially
had a fan installed to draw air through the core but removed it since I did not
find it necessary. Last Sunday with an outside air temp of 15 degrees on
the ground, fully opening the heater air valves resulted in an uncomfortably
warm cockpit in flight so the valves were partially closed.

Question
For you
guys already flying what are you doing about supplying air to your heater core;
cockpit air or dedicated outside air source?
For
those flying with recirc. air do you ever have windscreen fogging like you do
in a car on humid days in the recirc. position? I know in my Camry I
am seldom in the recirc position due to fogging but then again my exhalation
air is quite a bit closer to the windscreen than it will be in my
RV-9A...
If at
all possible I hope to be able to get by without running a fresh air
supply to the heater core...
