G'morning Together,
i have the standard vans exhaust muffler routed to the triangular TG-10 heat box on the firewall. i followed the advice of some threads here and sealed all kinds of openings at the canopy/cabin/fuse but the heating in my 7 is still only marginal. yesterday with OAT in the 20's my smartphone stopped working due to temperature. i'm tired to dress like somebody heading for an arctic expedition everytime i fly during winter.
besides preventing cold air from entering the cabin, the warm air from the muffler should freely run into the cockpit. looking at my heat box i figured that there are gaps (1/16 - 1/8) between the edges of the flapper and the heat box housing when the flapper is in the open postion (warm air in). i'm sure because of the gaps a lot of hot air does leak into the lower engine area.
anybody did seal these gaps? have an hard time to figure out how to do that. any pictures are very appreciated.
Cheers
Kay
