Though leaving the flaps closed means not so much heat gets out to the cab, still, even with the flaps closed and a good seal, some would heat would escape simply because the box is hotter than the cabin air.  Close the valve, and the box should not heat up, as no coolant flow.  Hmmmmm.......... .

I've got my shutoff mounted behind the glove box. Drop the box and thar
she be!

And, for a summer project,* I'm-a gonna remove the dash and do various
maintenances, including refreshing the heater box flaps. They're not
