Hi guys,

I'm looking for a best installation of a coolant heater for the cabin.

My heat muff works o.k. down to freezing, but I'm looking at components

that might offer better cabin warming. Perhaps you Canadians have

a list of parts that better describes what you used and

how you made connections within the cabin.



Even pictures would be nice.



Thanks

Larry,



The heat in my Pelican with the Stratus was amazing.  I posted pics in 

airsoob years ago - 

http://groups.yahoo.com/group/AirSoob/files/cabin%20heat/



It uses a VW heater core but I'm sure anything will work.  Just tap into 

the bypass loop and send that heat into the cabin.  You'll need two 3/4" 

holes in the firewall to get the hoses thru, with obvious care to 

preclude the 200 degree coolant from bursting into your lap during flight.



Mine worked very well for years but I removed it when I moved to Texas.  

I'd be happy to share any details on the box design, or you can contact 

one or both of the new Pelican manufacturers to see if they sell parts 

or heater kits.  Knowing your capabilities, you can come up with 

something pretty slick.

I have an auxiliary heater unit from J. C. Whitney: http://tinyurl.com/yb3tw8e 

It's a bit heavy at 7 lb. and provides more heat than I can use at the high fan setting. I've flown at temperatures down below zero F and the cabin was still comfortable. I have it installed just behind the firewall on the bracket that supports my radio stack. The water supply is tapped off of the bypass line that runs from the water pump to the thermostat. I have a couple of Tees and a water valve to control the heat flow. I usually run it at the low fan setting with the water valve part way open and it provides plenty of heat. On really cold days, I might run it with the valve full open and the medium fan speed. The high fan setting will provide quick defogging and cabin heat as the engine starts to warm up. It really has more heating capacity than I need for that small a cabin. I bought it because, at the time, I didn't feel like making a heater unit from scratch. 



I'm sure you could build a lighter unit from aluminum sheet, a small heater core and a couple of computer fans. You probably wouldn't need the hose Tees and water valve if your lowest fan setting was low enough. No heat comes out of the unit unless the fan is running, you could probably just feed the bypass hose in one end of your heater core and back out to the thermostat directly.

Let me explain the pictures better. 



The little airscoop on the side of the fuselage brings in fresh air.  It 

is boxed off on the inside and has a selector flap with two outlets.  

One goes to the inlet on the heater box before the heater core for "hot" 

and the other goes to the inlet after the heater core for "cold".  These 

inlets are the two 2" tubes sticking out in pic 427.  I mounted an 

automotive control panel with cables to control this.  The hot/cold 

cable just moved the flap.



The 2" outlet on the heater box (center of three outlet tubes) went to a 

panel mounted vent.  The two small outlets went to defrost (one pilot 

side and one pax side), and the bottom slot was "foot" heat.  Again, a 

cable from the automotive panel controlled this just like in a car.  

Very slick system that blasted out nice heat.  The panel vents are 

moveable eyeballs with vents that can be directed or closed.



The guy next to me with a cub used to put on a bunch of layers to go 

flying, and I would be taking layers of before getting in my plane.  

Toasty warm on any winter day.

What I did on mine was as Bryan suggested..I.e fed the bypass line thru the heater core with no valve...Just had 4 computer fans, run two for low setting and all four for high. I never noticed any heat from the core with the fans not running.
