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.

 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.

Hi Paul,
    I am building a modified Long RG RX8. I am going to use electric
truck cab heaters,
    Easy installation and no fumes. Joe might like to consider this.

Sounds like a good way to get back and fourth from the south island.
I used to have a distant relative living in Wellington.
