I like that for apparent ROI. Halved the monthly bill. If it really saved 600kwh/mo for 3 months of the year at 0.12/kwh that is about $216/season. (that is rough nominal cost of electricity where I am)

well we are basically at the end of the cooling season too. highs in the mid 60-70 range and its in the 50's at night.. so i haven't really been running it at all. i will be insulating the fan soon tho and i will post up on how that goes.. other then that i think a whole house fan is TOTALLY worth the investment.. i still plan on installing another fan at some point but all founds are headed towards the roof at the moment..

Well I got it all sealed up for the winter I didn't take many pictures.. Basically I went up in the attic and used that real duct tape and taped all the seams up. Then I pulled down the grill and put up a piece of the 2" foam and some r-19 insulation in the large hole and put the grill up to hold it all in.. I figure that's probably double the insulation I have in the rest of the attic at the moment..

Nice write-up. I have a cheap whole house fan right now that can displace all the air in our house in a matter of minutes. I throw fiberglass insulation strips on it in the wintertime, but I know that is nowhere near good insulation.
We are moving soon, so instead of fixing the current situation, I have been thinking about how to improve it at the next house. I came up with using a centrifugal fan to minimize the footprint of the attic hole. Plus they seem to be more efficient and quieter than propeller style fans. Has anyone tried using one of these? |

Centrifugal fans often aren't as efficient, but they can produce a higher pressure differential.
