Panasonic Whisper Warm?

Hopefully a pro will respond to your concern...

Many typical/various moisture issues don't affect me as I live in the Desert region of Southern California.

Install a good dampered roof vent and use well insulated vent material and I doesn't seem to be that big of a deal. Note, the longer the run, the more trouble this becomes. Running it out to a soffit is not a great idea - it neads to vent outside directly.

Hello and thanks for the response,

Jadnashua, the soffit vent method does in fact take the vent outside. It exits the soffit with the same vent housing that is used in going out the side of the home.
Also, It is true (from my research) that the shorter the run and insulating the run both reduce condensation. Will the damper that you are referring to also help?

Thanks,
Molo

Any time you can reduce unwanted airflow, the better.

They're ususally easier to replace from the top.

You want a Broan model QTRE080R, which is 80 cfm and 0.8 sones and can be installed replacign an existing fan (in most cases) without going into the attic based on the special installation features of this unit. Keep in mind this is avilable only in an 80 cfm rating and not with a light. The 80 cfm rating is far and away the most approprite fan size for the average American bathroom.
