Well, a heat pump (an air conditioner that runs in reverse) ! does work a little more efficiently than TTL logic for heating ! the house. My biggest problem is coming up with a way to duct ! the heat from the 11/70 to the rest of the house. It still seems ! that I end up with the heat on in the house, and the windows ! open in the room with the 11/70. What about something like an exhaust hood over the 11/70, and a fan? --- David A Woyciesjes --- C & IS Support Specialist --- Yale University Press --- mailto:david.woyciesjes@yale.edu --- (203) 432-0953 --- ICQ # - 905818
