We have a 1500 sq ft three level house in Oregon that is challenging to heat and cool. There is a daylight basement that is always cool to cold even with baseboard heaters. The first floor does fine most of the year and we have a wood stove that gets it really toasty. Theres also a loft that we use as a family room but gets really hot in the summer. Does anyone have advice on heat transfer fans. ( Tjernkund has one called a level to level transfer) I was thinking one on the main floor could pull warm air down to the DLB. ?? If I could find a reversible one I might be able to pull that cool air up in the summer. Any thoughts?
It's maybe too late for the basement (without work), but can you insulate more in the upper room's ceiling? That should help w/ the sun heating it too hot (will slow down the temp rise). Also, do any air sealing that you can. Leaks increase stack effect. It sounds like maybe the basement is not insulated sufficiently; slab? Foam under it? Fans, I don't know about.
