Since this system is bringing warm outside (fresh?) air in winter it makes sense to just use it as makeup air for a bathroom fan. So that's what I plan to do. I think a an 80 or 130 CFM Panasonic bathroom fan should be plenty to overcome the stack pressure and bring that warm air in. The advantage of doing it this way is that you avoid most of the draftiness of only warm, (not hot), air being blown on you from a pwerful fan. The trick is you have to make the house pretty air tight to do that. Otherwise the house will find some other way than the open duct to get that makep air. I've been spending a LOT of time making the envelope airtight. I'm also planning on installing a Aldes makeup air vent for those times when I can't, or don't want to, use the attic as a makeup air source. |
