Dico’s question got me thinking – what about those of us with a heat muff? The build manual says air must flow through the heat muff at all times to avoid excessive heat buildup. I used 2” SCAT tubing and a cabin heat valve from Spruce. When the cabin heat is turned off the system is still wide open but all the hot air gets dumped overboard. It seems like a pretty big waste of plenum pressure. How have others addressed this?

Thanks,
