My IV has the water heater with the blower and it works well. I am surprised how little I bundle up. I had a Kitfox III before that did not have a heater at all, as long as the sun was out a little it was always warm enough. Very surprisely!
My winter temps are in the low twenties for the norm.

I built a heat muff for my exhaust and it keeps me nice and warm and the windshield clear at -30F. Well, Warm is a relative term at that point. It is warm enough that I can fly with just thin cotton gloves and be comfortable. My normal gear at those temps are fleece bottoms and tops and my Klim jacket and pants with good boots. I wear what ever I plan on crashing with!
The heat muff takes about 50 bucks in materials (if that) and about 2 hrs to make and install.
I have a heater core behind the panel that is the size of two computer fans. I tape over 1/2 of my air scoop on the main radiator which will keep the motor running at 180-210°. (see the photo below) With this setup, I can fly all winter without gloves on and jacket unzipped.
I do have a strange situation where cold air comes up from the tail, so a hood or warm collar to keep this air from going down the back of my neck...

Folks.... needing some help with m Kitfox IV 582. The prior owner had a heater core installed in the cabin and I'd like to hook it back up. Question? Does it matter where you tap into the coolant system for both inlet and outlet to the heater core? If so, can you detail what the best setup is for max heat and maybe even add some pics of the engine-side setup not the heater core itself.
