John Harlow said:What would be the problem with ducting cool air from under a house to the
attic in warmer months to help with cooling, and just the opposite in the
winter to help with heating?
woudln't Your floor would get cold from the cold attic air, cooling the air
above it, and forcing your furnace to run more often?
Once you cyled the air completly once, the radiant heating from the earth
would take a while to warm the air under the house again,
more likely it would be the heat escaping thru the floor that would be
warming the air under the house,
so I think the net benifit would be little to none, ...
