REFLECTOR: Cabin Heat/air exit

[Mark Magee]

Alex,
Thanks, that makes sense. Armed with this knowledge there is an opportunity to regulate that suction side I suppose should we desire to focus on recirculated Cabin Heat, which from my read of this thread seems one of the better options for those days approaching 0 degs F at altitude.

Is it going out via the door seals (my guess)? I can't see any designed way out for the pressurized air from either cabin heat or overhead cooling vents. Methinks that air pressurized for heating the cabin is better than recirculated air as it floods any possible air leaks into the cabin with the heated air. However as there is no designed vent or dump of the pressurized air, is this situation best for our door seals and/or where ever else the pressurized air exits the cabin.

I heard some of you partially cover the cooler, but not sure if the can be risky if covered too much. Has any one had any experience trying to get more cabin heat?
