Give me a museum and I'll fill it. (Picasso) Give me a forum ...
That's some great research there samclem. I have not read thru the links yet, but I like the idea of the two 4x10 registers. Good point on wanting a return, so the conditioned air does not all go to waste - but I wonder if sizing the return a little smaller than the sources might be good, just to provide a very slight positive pressure, just enough to keep outside, hot humid air flowing in?
Hmm, I'm thinking I might hook up a manometer so I can see that I create a very slight positive pressure for my basement. Would be good to check in winter, to assure no back-draft potential for the furnace (which has a sensor, but best to not have the problem in the first place).
For sheehs1 - consider something like this:
Amazon.com: La Crosse Technology WS-9037U-IT Wireless Forecast Station with Pressure History: Home & Garden
I have a similar unit from LaCrosse that I'm very happy with ( I have three remotes now, outside, porch, and I move the third around to wherever I want to monitor), but my remotes do not report humidity. Put one of those in the crawl, and you can monitor and know that things are as expected w/o having to expose yourself to cobwebs. Plus, since it just takes a glance, you are more likely to actually check it.
