Hi- new to the forum here. I'd like to install a ventilation fan in my split level home in VA- mostly to expel the hotter air from the top floor into the non-climate controlled attic during the cooler hours. I've done some research on available models and understand the flow rates (cfm) and efficiency ratings (cf/watt), but have not found any info on what type of fan I should be looking for for my particular home. The fans I'm looking at range from 10cfm to 380cfm.
So my questions are:
1) Is there a rule of thumb for house volume vs flow rate?
2) Are there any strategies on where to place the fans, other than in the highest spot in the house?
Any info is greatly appreciated,
Pete
