A little noisy but, it's a fan mounted in the rafters under a hardwood floor. To be expected. Don't really understand why people would complain about a fan that makes noise. IT'S A FAN! It has moving parts and unless this is in a shed or a garage or somewhere not attached to the house, then you're gunna get some noise. This fan moves a ton of air and the variable fan speed is a super bonus! I can regulate the amount of heat/cool air that I want to come upstairs while keeping the basement cozy!
We probably got 3x to 4x the volume of warm air from the fireplace, through the overhead duct and out the floor duct. But the fan was so powerful that it set up a vibration on the floor allowing us to 'dial down' the rpms and eliminate the vibration and still get great air volume.
