Exhaust fans new construction: We're looking for a remote exhaust fan solution for kitchen and bath for our new construction. I've found something like this: http://www.kitchensource.com/range-hoods/ft-cvs275a.htm Do I need to have a separate one for the range hood and bathrooms, or can I get one larger one for both? We will have a total of 3 baths, a laundry room, and a range hood.

Because of the nature of what can go out thru the kitchen vent, I would be inclined to keep the kitchen on it's own short length ventilator instead of pulling smoke and grease particulates throughout your ventilation system.

I am puting our bathrooms and laundry on the outgoing side of the HRV with high rate timed switches in the bathrooms. Kitchen will be on a high volume dedicated thru wall vent.

Thanks for the advice.

I know this is contrary to what you are asking but the Panasonic units are really very quiet. They are cheap and come in a variety of CFM (some fixed, some selectable). I believe running 6" ducts instead of 4" helps cut down the noise.

What I ended up doing was putting the bath fans on motion sensors. I can't seem to program my family to use them otherwise.

That is why I am putting the bathrooms on the HRV, it will run on low most all of the time anyway...

I'm actually looking at doing that since I won't have one blower for kitchen and bath.
