Mark,

This is in an RV, but I just put a heater core into a box with flape= r valves to direct air and a "heater valve" in the water line just like a= car. The core has two copper lines that project forward through th= e firewall, so there are no hoses in the cockpit. The hoses and wat= er valve are forward of the firewall.

As you can see, air is taken from the NACA fresh air vent. It = can be directed through the core to the floor or up to a defroster vent, = or any combination thereof. The water valve takes care of temperatu= re control. It works exactly like an old car.

I can discern almost no help cooling the engine by opening this thin= g up. At any rate, when cooling help is needed here in Texas, putti= ng this on full blast would probably melt your shoes.

Is there a "best practice" for cabin heat/defrost system= s 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 tailp= ipe, 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. T= he exhaust muff seems
like the lighter and simpler solution. On the o= ther hand, with proper
ducting, the heater core could add extra cooli= ng during climb-out.

Comments welcome,
Mark S. (hot oil exchang= er is out of the question)
