Do most of you install one cabin heat box, or two? I've seen an RV-6 that had a cabin heat box coming off of each of the heat muffs on the left and right branches of the exhaust manifold. (It also had a third heat muff on the crossover tube for carb heat, but that's not germain to my question.)
The word from that owner was that two carb heat boxes was BARELY enough at altitude...and he had gone through the usual steps to seal the cabin against drafts.
I just installed one cabin heat box in the per-the-drawings location, i.e. just below the firewall recess. I'm trying to figure where -- if at all -- I should install the second one. I'm a little paranoid about just choosing a location only to find later that it interferes with something forward of the firewall. My firewall is presently bare.
Oh, one more question: what have you guys done about windshield defrosting, if anything?
Your opinions and suggestions, please?
Thanks,
Martin
