Supplemental Cabin Heat.

i dont have a bravo, but i have a rocket. that seems odd. i sometimes i want more heat near my feet i take my checklist and drop it in front of the floor vent and it pushes heat to both sides of plane. most of the time its too warm. -20 is never a problem. i would check your mixing box, and your shrouds for leaks. the only time i sometimes lose heat is when its really cold and i dont keep enough power in on descent.

I found a couple of half squares used to keep straps from chafing loads on flatbeds. Turns the air left and right or the 45° angle will direct the air up from the floor. Helped out a lot yesterday.

I have found on my Ovation, if it is super cold and I am running LOP, I don't have enough heat. Running 75 ROP gives me more than enough heat. The only thing I can figure out is the flame goes further down the stack thus providing more heat to the exchanger. If you have ever flown a twin with radials, you know what I mean. That all said, in cold climates as when I was flying out of Anchorage, a check S/O counseled me to get a pair of silk long johns. They are amazing, to the point I wear them regularly in the winter even now. Besides keeping you warm and toasty they do not overheat you when you enter a heated environment such as a heated room or cockpit. Really good for going inside and outside without suffering over heat or under temp. Land's End, LL Bean et al have them. Not cheap but worth every cent.
