Paul,
What is the preferred design for a cabin heater using the rotary?  Do you
use the oil or the water?  What about an oil to water cooler using an
external water circuit?  I am building a pusher.  Thanks for any help.

Perry Mick uses an oil cooler under the cockpit
on his Long as I recall.

Joe,

The highest temps are from the exhaust.  A water exchanger will require a
heater core, a fan, lots of coolant hose, and a gallon or two of H2O. If it
springs a leak, you could be faced with scalding hot water being sprayed on
your legs/feet, and at minimum, a fogged up windscreen.  Bottom line... an
exhaust heat muff provides the most heat for the least weight penalty.  If
you do go that route, spring for a CO detector.
