Since you will want some form of heat, I would think that
is not a bad idea. Sort of what the Lycoming guys use except taking the
heat off of their exhaust headers in their case. In fact, you might be
able to use some of the ducting and air valves they use - might check into if
you haven't already.
I will tell you (from Personal experience brrrrrr) that if
you don't fly with a thermostat using coolant or oil heat during really cold
temps won't keep you warm - well, unless you block off one of the cores
{:>). Reason, of course, is I saw my coolant temps down to around
115-120F flying to Texas and that just wasn't enough to provide sufficient heat
to keep my toes warm. However, cowl flaps would probably provide the
answer.
FWIW

My thought
has been to mount a heater core on the fire wall and have coolant flow through
it all the time. Using a damper system either dump the hot air out the
bottom of the cowl or direct it into the cabin. The only problem I can
see with this is the space on the firewall needed to mount the heater core and
air plenum. Any thoughts on this?

Yeah, Joe. I have an oil cooler core
sitting on my side of the firewall that extracts heat from the coolant
system. However, the small amount of heat its capable of
extracting is so small compared to the thousands of BTU of heat you need to
get rid of each minute from a flying rotary that the effect on cooling
is nil.

Has anyone designed a separate system that
extracts heat from the engine compartment or components to heat a fluid in
a separate system using a heat exchanger to dump the heat into the cabin
and a separate pump? This way you are not making this system part of
the engine cooling system and can run lower pressure and be able to shut
it off without affecting the engine system. I was thinking of a
device that subarus had sandwitched between the oil filter and the
block. Any thoughts?
