I want the basement to be warm, at least in the mid 70s. I want to keep it dry too.
Pumping down warm dry air is my goal for the summer.

But, trying to use the basement stairway as a duct isn't working real well.
Yesterday, the air at the top of the stairs was over 100F..
Not enough is being pulled downstairs into the basement.

If I had been able to install a 6" duct between attic and basement,
it would have worked a lot better than it is now.

Lately, I've been running a large floor fan during the sunny part of the day,
to blast the stairway with cool air from the basement.
That keeps it from getting too hot at the top of the stairs.

At least, I'm running the floor fan off solar PV power, so no money is going to NStar..
