Sorry, but I just don't understand the thinking by Cessna engineers, nor why no one has made a modification through field approval or STC to remedy it.
The reason a combustion heater is necessary on most twins is simple - the engines are out hanging under the wings, so very inefficient to try and pipe that excess heat through an exhanger into the cabin. Our engines are not out under the wings- we have one right in front of us - just a like a single engine design.
On single engine airplances it is a simple process to set-up a heat exchanger type system, no extra fuel or flame needed, to get heat into the cabin. You still have to have proper carbon monoxide detectors and sound exhaust system checks done under any system. Why not just heat the Skymaster the way a single engine plane does it?
Has anyone ever tried to use a mod that gets nice engine heat into the cabin and eliminates the combustion heater?
