Can this fan be used in an attic where the temperature drops below freezing? I live in Chicago, I assume it can go as long as 0 degrees at the worst.

I am using it with no issues and the temp in the attic has seen below 0, last year when we had the biggest snow year since 1896.

It has been in my attic. I don't think it went to 0 degrees but was below freezing and never was an issue.

No. This is not suitable for attic use. There are several attic exhaust fans on the market that would work much better. Amazon has a couple different Broan roof mount units,but your use is dependent on attic size, attic shape, inlet air size, placement, power supply, and other air outlets. I would recommend thermostat and humidity control. I would suggest contacting a building or roofing contractor for help. It can get a little complicated to properly size a unit.

SPEC'S: Avoid temperatures below -10C (14F) or above 60C (140F). However, I tried it in my great cold City of Chicago last week when it was below 0, and it worked......barely.

Depends how far up in Maine you are. I lived in Ct and it kept my small room, about 650 sq ft at 68 degrees easily. The fan only stays on until the unit is cooled. Set it up automatically and don't worry about it. Nice machine

I have never had a problem with cold air leaking in. I do live in Florida now and I really don't have cold weather compared to Illinois where I am from.I even had one of these fans in my home in Illinois and still did not have any problems.

I'll try and break the tie. Its an electric fan mounted in a heavy aluminum base (I dont think the pictures do them justice, these things are pretty big) that requires sunlight to shine on one side in order to work. IMO it doesnt really make any more noise than any other fan that moves a similar amount of air, my fridge is way louder. You would wind up with a 12" or so circular hole in the roof that the fan is fastened to the outside of; you would need to put some sort of grill over the inside of it to keep fingers out of the spinning blades. It probably would not amputate a finger but could easily make a nasty cut. Plus its not the prettiest thing on earth to look at. You will also need a substantial source of air into the room otherwise you will be creating a suction. If the two rooms are connected you could swap the wires on the motor of one of them (would require some electronics skilz) and have one suck and the other blow and get a draft through the area. You will also need to provide a way to close it off completely in winter to avoid letting cold in. You could put a switch on it in conjunction with the closing mechanism so it doesnt run when closed. Additionally roof vents (powered or not) are not as insect proof as window screens, the openings are bigger. Might be a consideration for inhabited areas.

I don't believe it is specifically designed for outdoor use, but if it is used in a semi-enclosed area like a screened-in porch where it is not directly exposed to rain, it should work okay. I've seen similar fans mounted in the ceiling of front porches. Make sure it is properly grounded and powered through a GFCI breaker.

I use my fan in my garage. I am located in Southeast Georgia, and relative humidity is always very high. I have not had any problems with its operation or with it rusting. I am glad I bought this fan, and I think you will be happy with the performance and the esthetics. I would recommend it for under a porch awning.

Yea, provided that the condenser does not need defrosting. To prevent ice build up on the condenser the fan may continue to run after the humidity level is reached.

Depends on where you live. If you are in a region that does not have hot summers, then you may not need an attic fan as you can address any ventilation needs through other means. However, if you live anywhere it gets over 90 or so several weeks/months a year, then an attic fan will be well worth the investment (most likely). If you have ever been in your attic when it is over 80 degrees (much less 90 or higher), then you understand the heat that builds up. Attic fans, with adequate ventilation - as then need to pull air through the attic, can dramatically lower the temperature and thus your cooling bills. Depends on where you live.

This fan will work very well for that room! Using mine in a slightly smaller area (132 sf) and only run on low speed to circulate AC from ceiling in the warmest room in house. I believe you will be happy.

Not sure how cold your attic gets. But it shouldn't be subjected to freezing temps, it will void your warranty if the pipes freeze. The heater or outlet pipe should be at least 24" from any combustable materials, and should not be installed under any water pipes or A/C lines. Required clearances are 12" above and below the heater, and 6" from either side. I was confused about the required 3/4" water feed line. When I called customer service about the size of the feed line. They told me it reguires 3/4" in and out for at least 1 foot. I went with a water feed line of 3/4" copper tubing for 5 feet in and out. My unit works great, and happy I went with the Ecosmart. I didn't see anyone else with a Lifetime Warranty, and made in USA to boot...

There are some good websites with design advice. They recommend installation near the outlet from the house. This is their reason: If you put the fan in the basement and run a long pipe through the house, any leaks in that pipe may release gasses into the house. If you run a long pipe from the basement to the fan in the attic, any leaks in that pipe will draw air in from the house. The air that runs through this fan is very humid, and they say that in cold climates, ice in a long outdoor pipe above the fan can be an issue.

I have owned 2 of these fans over the years & I love them. Both of mine were installed indoors in my family room . As long as it won't get weather on it, I think it would work in the space you are asking about.

No. The power supply in this unit produces a little heat itself, and I would NOT suggest installing in an attic. First summer it was in there it would die for sure.

The fan is good in damp but not wet conditions.As long as it is out of the rain & snow it should be okay. We have it I the house & love it.
