Bath exhaust fan with in/outside diverter

Daox · 06-01-19, 12:52 PM

We are in the initial stages of planning for redoing our bathroom. Our house is fairly leaky, so in winter, we tend to put a pedestal fan blowing air into the bathroom to get some moisture in the house as well as retain some of the heat from the shower. So, I thought why not do a bathroom fan that vents to another part of the house as well as outside? It could vent to the hallway pretty easily with a little ducting in the attic. A diverter can be used to vent air outside in the summer.

What do you guys think? Do you see any issues with this? My only concern would be moisture build up in the ducting in the attic.

Here is an image to show the idea a bit better.
