Just finished my ductwork and blower to move the heat around my house. Here is where the intake it. It's at the peak of my vaulted ceiling where my stove is. Ignore that hole next to the vent Here is the insert Here is a pic of the 200cfm whisper quiet blower and associated duct work. I had to add a section of spiral duct in one of my rooms ceiling to get heat to the master bedroom. Still have to add a vent in that spiral duct to heat that room. All together it cost about $400 parts and about two weekends of my labor. All I have left to do is a few finishing touches of spackle and paint and add some return vents in the bedroom doors. I may just leave the doors open this winter if I don't get around to it. Anyone else try this? My house is a 1,500 s.f. ranch.
