Discussion engendered by the photograph of a combustion heater in this post continues. I've been asked to provide more illustrations of aviation heater installations but the only one I have is by coincidence in the same airplane, two years earlier. The earlier photo was taken the same day work was being carried out on the heater, so it may not be in fully installed condition, but it looks almost exactly the same to me.
Here's the photo taken two years ago in a hangar in California.
And here's the one from last week, the same heater on the ramp in Saskatchewan.
If anyone else would like to share an aviation heater photo I can add it to the gallery.
