Rated 4.4 out of 5 by 74 reviewers.
Rated 4.0 out of 5.0 by Vent an HVAC utility room I needed to vent a utility room that housed the HVAC and hot water heater. With the heat running the temperature would easily reach over 100 degrees inside the room. I installed this thru-wall vent and paired it with a Suncourt ductstat plug-in temperature sensor to turn it on and off automatically. The fan keeps the room from going over 87 degrees, which is a huge difference (fan is on high). The power cord is on the front of the fan that exhausts the air. I needed it on the other side and was able to push the cord backwards, cut out a notch in the drywall, and feed it through the wall. The fan is fairly quiet even on high. Overall, I am very pleased with its performance. I gave it 4 out of 5 stars because I would have liked the high setting to be a little stronger for my purposes. March 2, 2015
Rated 3.0 out of 5.0 by Easy installation and moves a lot of air, but could be quieter and more attractive I installed this fan in less than an hour. I located my studs, cut the holes with a jig saw, and it all went smoothly. Fitting the two tubes together took a little bit of jiggling things around, but it went very quickly. The tubes are flexible, so if you have trouble getting them to seat properly, you can flex them somewhat. The fan does move quite a bit of air on the low setting. I doubt if we would use the high setting at all. I installed this to bring warm air into a cool bedroom. I don't think I would use this fan again for this application because: >It's a bit loud >It's industrial-looking . Despite the grid on the cover, the inner guts are in full view, and it doesn't look very good. I would use this fan to bring warm air into a workshop or garage, however, or someplace where the fan wasn't visible. December 28, 2014
Rated 5.0 out of 5.0 by Good heat transfer for wood stove Bought this to transfer heat from wood stove through wall into our bedroom. Works great. It's been down in the 20's and we've been plenty warm. October 29, 2013
Rated 4.0 out of 5.0 by Easy to install This fan was easy to install. We have a split level and the heat from the pellet stove would not reach the living room. Installed the fan through the living room wall and this fan keeps this room at 63 degrees which is just fine for me. January 1, 2014
Rated 4.0 out of 5.0 by Good product. The unit works well, and it is relatively easy to install. It is a little bit louder than I expected, might interfere with sleeping if it is mounted in a bedroom wall. It seems that most of the noise comes from the motor bearings, and it is noticeable on both speed settings. The unit can only be installed with the cord coming out on the side of the fan discharge. The cord is approximately 10 feet long. April 21, 2015
Rated 5.0 out of 5.0 by This is a HUGE asset to our home! We have a bedroom in the lower level of our house and it is always cold in this room. The natural gas heater is in the next open spaced room (basement type) and the heat would never stay in this bedroom. We thought about installing another gas heater, but then my husband decided to try this and WOW! This sucks the heat right in and heats the whole entire bedroom! This has saved us a bunch of money! I give it an A+ March 25, 2015
