If my house can be as cool as it is outside at night that would be perfect! Without having to use a whole house fan to exhaust all the air in the house that has been conditioned and trying to keep the indoor air as clean as possible. I thought i would try it and see what happens. I do have a high mounted industrial canarm exhaust fan @ the top of the ceiling good for 650 cfm and an itake that is 5' off the ground for fresh air while welding etc. It all depends on how cool i can get the slab temp at night until the morning. I just need to plumb in the garage water loop with the heating coil for the air handling unit and either use an existing circ pump or get a another separaste pump on a thermostat.. BUt your most likey right in the sense that it will be hard to do. I'm going to concentrate obviously on getting this top working and the cooling thing will be pushed back until 2015 at which time i will probably just put in a AC coil
