Rick, what you need is one of these gismos:
Vent to the interior during the winter, because furnaces with humidity control tend to dry out the interior wood and air.
Humidity during the winter is
a must or else lung infections and wood cracking happen.
Notice I insulated the stack as well. The rim joist is spray-foamed, but the long metal tube can act like a heat sink to the outside.
The no-circulation situation sounds like a problem. You're going to need conditioned air going through the basement or mold develops. Maybe you can cut into a supply pipe/run down there, and add a vent?

For super-sealed houses, look into ERVs for fresh air exchange.
It's a ceiling fan/heat exchanger which runs on ~20W+/- and is about 80-90% efficient. My Panasonic was ~$400 for the unit itself.
