I use the coolant through an small oil cooler in the cabin. I have a
shut off valve. I think a compromise might be to have the small heat
exchanger under the cowl (rather than in the cabin like mine) with a air
duct into the cabin. That would address your concerns about the C0 and hot
ethylen-glycol.

Subject: [FlyRotary] Heaters/defrosters
Is there a "best practice" for cabin heat/defrost systems for rotary
a/c. Those of you that are flying, how did you approach this item. It
seems to me that with all that heat going out the tailpipe, it is a
no-brainer... except for the carbon-monoxide thing. Then again, I don't
want to be scalded with hot ethylene-glycol either. The exhaust muff
seems
like the lighter and simpler solution. On the other hand, with proper
ducting, the heater core could add extra cooling during climb-out.
Comments welcome,
Mark S. (hot oil exchanger is out of the question)
