I think the reason the basement air temperature is changing very little,
is likely due to the coldness of the floor slab. It's about 57deg F everywhere in the basement.
I think it's sucking up the heat like a sponge..

I've been thinking about sticking a sensor in the slab, so I can monitor it's heat.
I'm a little surprised to see the slab so cold, this early in the winter season.
Temperatures this month have been pretty normal.
Nothing that would cause the slab to be extra chilly..

It was 46F on the slab last winter.. (‎February ‎05, ‎2013)

That seems a little too cold, and it's got me wondering how much the slab
warmed up over the summer? All summer, it was 65~70F in the basement.

Maybe the ground around the house and under the slab didn't fully recover from last winter?
Back in the good old days, the slab was warmer.. Maybe around 65F this time of year..

I'm thinking about something very weird right now..
The possibility of using this attic air heating system,
to heat my basement during the Summer of 2014..

If we had enough low humidity days, I could run the blowers and easily
heat the basement air to 72~75F, on the summer days..
Unless the slab has ice under it next summer!
