It's likely that some percentage of the heat you're recycling is coming from your house... either way this is a great project.
It reminded me, in certain respects, of some exergy analysis reports I have come across for some commercial European buildings, wherein the heat decay through a building was followed and utilized appropriately at various stages of decay... a whole new way to think about heat.
I'm curious if the heat build up in the attic that is added to your room heat, ever gets excessive, enough to cause you to over-ride the fan from the attic.
If that ever gets to be the case, it would suggest some heat storage for later use... like maybe an air-to-water exchanger in the attic, and a large water heater tank in the basement, to ease you through the chilly evenings.
Or maybe storing heat all the time for DHW preheat.
...anyway, great project!
