REFLECTOR: Rear Seat Heat

Sat Apr 26 20:22:09 CDT 2008

Hi Doug-
I bought two 1/2" 3 way ball valves to direct the oil- they are standard
hydraulic plumbing parts they had female NPT threads, to which I installed
matching AN nipples- I like your idea with the firewall mount- I just like
to get the heat down on my feet since they are the parts that get cold
first!

Alex,

Using an automotive heater core sounds like a good idea. I didn't know you
could run oil through it. If you've got the part number handy of the valve
you're using, it would save me the trouble of finding one. 

I'm putting my oil cooler in the engine compartment, mostly because I don't
want the extra weight of an extra 22 feet of oil line. I was going to rig up
some ducts that could switch the oil cooler's intake air between outside air
and recirculated cabin air, but now I think I'll just mount a small
automotive heater core on the cabin-side firewall to recirculate cabin air.

is about 5” x 12” x 1” thick. then made a fan pack from 3 flat fans attached
to a sheet of aluminum that covers the entire core. Fans can be turned on
sequentially for various “speeds”- I am running water/coolant, but you
should also be able to run oil through the core and achieve a similar
result. It is pretty small, can fit under a rear seat, but you will need to
tee into the lines running in the duct- I put a valving system on it to
bypass if I have no rear seat passengers- I thought I had some pics here,
but I cant find them- if you want a picture, please let me know.

air!

heat out of the oil. Does anyone have a electric powered heater that works
maybe?

the oil cooler lines run through and pick up that heat and allow it to blow
into the rear cabin. This would require that the vernertherm close off and
force oil through he cooler and the lines during the winter.  If the cooling
air to the engine isn't reduced during the winter flying, then the oil won't
get hot enough to do much cabin heating.  This could be done by
restricting the NACA scoops by reducing the inlet area.

gain some oil cooling from the oil lines for the summer months.  If you
calculate the surface area of the two 10' lines going through the plenum, it
is almost as much as the surface area of the oil cooler.
