SuncourtTW208P Thru Wall Fan Hardwired Variable Speed

I used this fan to bring down the heat in a tiny room where I keep my networking and internet routers. The room was getting too hot and i was afraid the electronics might burn out. This fan brought down the temperature. I did not measure the temp before and after but it feels about 5 degrees cooler. The fan is very quiet, which is a huge bonus!I have the fan on 24/7 for about 2 weeks now and it's still performing well.

11/28/11 We use a woodstove to heat the house in the winter. The room adjacent to the living room was always cold so we looked for a way to move warm air from the living room to the adjacent bedroom. I researched several fans and this one fit our needs because we specifically wanted a minimum of 100cf of air per minute - not be limited to just 100cf per minute. The Amazon price was the lowest.The Amazon website for this fan is lacking in the technical information we needed to make an informed purchase so I had to go to the manufacturer's website. This fan moves 100cf (low) up to 200cf (high) of air per minute using an adjustable speed "knob" on the front of the fan and it was supposed to be pretty quiet. It also has a rotating grill to direct air flow which is convenient. Some of the other websites offer the fan without the rotating grill at a lower price. I'd never consider that option because we want to be able to direct the airflow as needed.The installation was not difficult. I recommend getting the wax tracing paper found in the sewing department of a fabric store or something similar to transfer the template outline to the wall. It makes it easier to cut the sheetrock without having to mess with the paper template getting in the way. You can cut it with the template, just make sure you securely tape it to the wall (use blue tape not duct tape).We put the fan about 4' from the corner and 6" from the ceiling on the wall nearest the woodstove. It's in a great place to capture the heat and move it to the next room.It helps my husband is an electrical engineer so he was able to do all the electrical work. He put a light switch (the flat decorative kind, not the regular toggle kind) on the wall below the intake side of the fan. This allows us to turn the fan on and off from the living room where the woodstove is located because we don't need to change the fan speed.Also, having the switch on the output side room would have been inconvenient for us (and probably not necessary since the on/off speed control is on that side of the wall). Besides wanting to control the heat transfer from the room with the heat, every now and then some evil smoke sneaks out while I'm reloading wood. I don't have to run around to the other room to cut off the fan while I'm trying to get the air purifier turned on to get the smoke out of the room.We did put insulation in the wall around the fan (as suggested by another reviewer). I don't know if it helped; however, we had the insulation so it wasn't a big deal to use it.I said earlier the output of this fan is 100cf to 200cf. The adjustment knob allows for very minute adjustments to the fan speed. This is important because you need to find that sweet spot between air flow and fan noise. This is an inexpensive fan and even though the paperwork says the fan is balanced, our fan makes more noise as the speed increases. It wobbles on high speed; however, that doesn't concern us because we would never use high speed. Wobbling on the higher speeds is the only reason I gave the fan four stars instead of five.I can't find a way to import a picture or you'd be able to see one of the nice features of this fan is it's pretty discrete on the input wall. We have it high enough on the wall so it's functional yet out of the way. Both sides of the fan can be painted - I'd recommend you do it before your final installation so you don't have to mess with taking it down and putting it back up.Overall, we're pleased with this fan. The temperature in the adjacent room is significantly warmer and the minimal fan noise doesn't bother us at night.ETA: 12/13/11 I changed the stars from four to five. This fan does a very good job for the price. I now have the fan speed halfway between 100cf/minute and 200cf/minute and the sound is barely discernable unless you're standing right under it. The reality of it is there's all that power in that small housing so it's going to make some noise. However, my ceiling fan on high makes more noise than the wall fan. We've had it in the wall for a couple of weeks and have been pleased with its ability to push enough air into the next room to keep it at a comfortable temperature.ETA: 12/27/12 It's been a little over a year since we installed the fan and I am so glad we did it! Right now the outside temperature is 26 degrees and we're nice and warm in the rooms that get direct heat from the wood stove and I can walk into the bedroom and not get slapped in the face with cold temperatures (as I did "before fan").The bedroom will never be as warm as the rooms that get the direct heat and that is fine with us because we want the bedroom to be a little cooler when we sleep. That being said, this fan does a very good job at keeping the bedroom significantly more comfortable in cold weather. The switch we installed on the wall has been a convenient feature and I recommend anyone installing this fan also put in an on/off switch.I still can't figure out how to put a picture in this review so I could show you the location of the fan in relation to the wood stove and also where we put the switch so I'll try to describe our setup.We have the wood stove at an angle in a corner in the living room. The fan is on the adjacent bedroom wall straight up from the stove (about 5' from the top of the stove to the fan - we have low ceilings so the fan is about 6" from the ceiling). The on/off switch is on the stove side of the wall about 4' from the floor and over about a foot from the stove so I can easily get to it and the heat from the stove doesn't affect it.We chose to put the on/off switch on the stove side of the wall because that was the most logical place for us to control the fan. There have been a few times I've let smoke out of the stove when I added more wood and it was easy to reach up and turn off the fan so the smoke wouldn't blow in the bedroom. I keep a Holmes air purifier in the living room so I can turn it on when I have "duh" moments such as that. Thank goodness those times are not as frequent as they were when we first got the stove all those years ago.My husband and I were talking a few days ago about how much we liked the fan and why did it take us so long to get one. I reminded him of all the research we did in years prior to buying this fan and just couldn't find a "good" fan. We didn't want to cut a hole in the wall and then find out we made a mistake.Then I found this fan on Amazon and did more research and we've been very happy with it. I cannot speak to other people's experiences; however, for us this fan was an excellent choice.

This is exactly what we need to share room air from a fully conditioned space to a small add-on room that we've turned into an extra bedroom. It was easy to install, operates perfectly, and is quiet to boot. The variable speed fan is a boon, and the ability to aim the output by spinning the vent dial makes it adaptable to a wide range of situations.My one lament (and it's a small one) is that the wires that emerge from the internal electronics box are quite short, and composed of stranded wire. It was a challenge to fit wire nuts to it.Other than that small nit, this was a great purchase.

Bought as a gift for friend who heats home by 70% wood and fan moves the warm air to the living room and upstairs. They love the adjustment that regulates the speed as you do not need much, just enough to move the warm air into the next room and upstairs. It even looks nice on the wall/ A great product.

The unit works well transferring air from one room to the other. However the fan is bit louder than I thought it would be. I've tried using it at different levels and still has a noticeable motor whine.
