Review: Mounted it vertically on wall. Pretty Quiet. Recommend. - Have a large upstairs master bedroom which due to its north-west exposure becomes unbearably hot from afternoon and into the early evening. Our summertime electric bills are crazy expensive primarily because of the AC trying to keep this room comfortable. Due to the room's vaulted cielings, I could not install this fan horizontally so I mounted it vertically as far up as possible on the one wall that borders the attic. Worked like a charm and we are now easily evacuating the hot air from the room into the attic and creating circulation with cooler air from other areas of the home. The noise of the fan is surprisingly quiet. I chose to re-orient the blower and the fan outlet doors from original 'horizontal' configuration to vertical so that the outlet airflow would not blow against the adjacent insulation in the attic. The manual shows these two possible configurations but does not elaborate on how to accomplish it. Actually, not hard at all to reconfigure... remove 3 nuts mounting the blower then rotate and flip, and then relocating the outlet doors on the exterior were obvious with no explanation required. Currently using a standard wall light switch to turn on/off while searching for the best 'cooling only', a.k.a. close on temp rise, a.k.a 'fan ON', line-voltage thermostat... the line voltage requirement is the wrench thrown into the plans since all offerings available only include quite rudimentary models with seemingly no digital or programmable options (anything beyond simple mechanical is for 'heat only)... finding a robust thermostat solution seems to be the most challenging part of this project.
Review: Great product so far - Works great so far. We've only had it in for a couple of weeks. I didn't want a giant hood over my open concept kitchen. It's tucked away nicely above the island. I can feel the air flow when I turn it on. It's very quiet for the size. I use a timmer switch for it and that works great! Easy to install. I think it could also be great in a large bathroom to suck out the shower steam.
