Whole house fans generally are not used in the winter months right?
I mean you'd suck out all the heated air that you paid for.
If you vented it only to a bathroom, that would be interesting.
Nothing creating a vacume in a small room.. Try opening the door
with it on.....
Do it correctly and buy yourself a nice fan. Panasonic
make some really decent and quiet bathroom fans.
habbi is asking about an air exchanger, ie a heat exchanger, not a
whole house fan or something that recycles air. An air exchanger pumps
air from the inside out, replacing it with incoming air. In the
process the heat is exchanged, so that most of the energy is not lost.
As for the bathroom fan, I would certainly think you would want one
without regard to having an air exchanger. Bath room fans take care of
point sources, ie humidity from the shower, odors, etc. From a
practical stanpoint, I don't think it's going to work trying to tie it
in to an air exchanger. There are some big problems that aren't worth
solving. First is logistics. An air exchanger is typically located by
the heating/cooling system, not near a bathroom ceiling vent.
Another is tieing it in, getting air to go the right way and not back
into the heating system, etc.
Best solution is just a regular bath fan vented outside. You could put
it on a wind up timer like used for bathroom heating lamps if you're
worried about having it left on and taking out too much air.
When I say plumb it into the air exchanger ducting I am talking about the
duct that is on it's way out of the house, taking out the bad air. The
ducting from the bath fan would have a "flapper" to prevent the bad air
exchanger air from going to the bathroom. I do not want to run the bath fan
ducting in the attic and I would like to keep the number of outside vents to
Not sure what your asking. Sounds like you want to use the
air exchanger output duct to also vent the bathroom fan
ie. one duct being fed by two separate fans.
I've got an air exchanger. It can move a lot of air when
going full speed. I doubt a bathroom fan would be able to
overcome the "back pressure" in the duct to do much good.
Can you use the air exchanger to vent the bathroom.
My exchanger vents two bathrooms, utility room, kitchen,
living and dining areas. The system usually runs at the
lowest speed all day. Each bathroom has a controller that
kicks the system into high gear, acting like a bathroom
