Here's some from Canada. A pretty good price too. http://seareycanada.com/Aircraft%20C...%20Heaters.htm
I bought this one last year. Last winter was so mild I haven't installed it yet. It looks to be very high quality. http://www.universalpartsinc.com/sho...750255&c=10550
Thanks for the replies everyone. Norm I may take you up on your offer. Maybe when Jeremy is back out west and I finally go see his plane.
Has anyone reversed one of the fans and drilled holes in the glare shield for defrost?

Yes, someone mentioned that they had done that in a previous thread. seems to me that that might not be a bad idea. There happens to be so much blow by from the top of the fan I am not sure if I won't be getting that effect anyhow. It feels to me that only half the fan output makes it through the heater core.

I wonder what kind of DC motor it is? If you could reverse the polarity so it went backwards when you needed defrost and forwards when your wind shield was taken care of.

Josh, these are simple pc fans. Many places sell reversible fans. For that matter, many also sell water cooling pc radiators that are set up for 1 to 4 fans and also drilled to accept the fan mounting and with various coolant inlet and outlet sizes and locations. Try http://www.frozencpu.com/ for both items.

Several years ago I helped a friend finish his series 5. His plan was Alaska flying and wanted defrost. I made a fiberglass - J shape that would capture a bit of the downward forced air and direct it up and through the glare shield. It was made by carving the desired shape in foam, covering it with fiberglass then carving out the foam. It was on whenever the heater was on. Actually there were two parts connected by a length of SCAT tubing. The top fitting was fabricated the same way and took the round from the SCAT tubing and reshaped the flow to a long oblong to direct the air across the windshield.
