So as some may know, I had scott out to fab me an OAK this summer. Last night was the first night I could really test it out. in and of itself, it seems to work fine. however, I still feel a wicked draft sitting in the living room.... which is what I was trying to solve in the first place. I have a level below the stove grade in my split level home.... It gets chilly down there. I'm thinking that now that its not grabbing outside air through the cracks, its grabbing up and pulling in the cold air from downstairs :/ Granted I only ran it a few hours. but I'm wondering if this isn't really going to solve my problem at all, or if running it longer will eventually fill out the whole house with the warmer air and start its 'max heat' recirculation process more or less?
