    Solar Options For Your Attic Ventilation

    Solar Powered Attic Ventilation - Pittsburgh Today - Live KDKA TV

  • Effective attic ventilation requires air to exit at or near the peak of the roof and replacement air to be drawn in under the eaves of the house, via soffit venting. The Home Ventilating Institute (HVI) recommends that powered attic ventilators provide at least 10 air changes per hour to equalize attic temperature.

  • 349BR is rated 4.0 out of 5 by 13.
    Rated 4 out of 5 by from Great product Nice fan matched the color of my roof works fine turns on & off when needed, except I had to change the thermostat I added a humidistat to it. The other thing the location of the thermostat is under the fan so when it rains it splashes on the thermostat & rots faster, dont like that, I purchased this fan before, so I know, Broan should have a made better thermostat cover to protect the inner parts of the thermostat.

    Rated 2 out of 5 by from Makes alot of noise Great fan except it's incredibly noisy. When it's on you can hear it from any room in the house. It does pull alot of air and looks nice but it's a headache to have on. It's pretty dissappointing to go through the hassle of hiring an installer just for it to be so noisy. I'm overal not happy with the fan because of this one key defect.

    Rated 3 out of 5 by from Doesn't last as long as they used to Put 2 of these in in 1980. Both lasted till 2010 (30 years). Of the two, one stopped running at all and the other still ran OK but it had gotten noisy and the neighbor paid for a replacement. One of those I put in in 2010 has now failed (6 years). I don't know if it was just a bad one or if the manufacturing quality changed between 1980 and 2010. I suspect it did. I'm not sure any other brand would be any better as I suspect they are all now manufactured in cheap labor countries with marginal quality assurance and least expensive materials. So, I'll be ordering a new one of the same model so I can just replace the fan and control unit from inside the attic without having to muck around with roof shingles to replace the whole housing that I'd have to do with a different brand or model..

    Rated 4 out of 5 by from Great job for about 8 years My fan died after about 8 years. Other than that it worked just fine. Could not be more pleased, all motors die sooner or later. Considering the extreme attic temperatures I was surprised it lasted over 4 years. For the price at Lowe’s you can’t beat it. Off to get another one!

    Rated 4 out of 5 by from pleased customer We installed it in our garage attic in mid August 2014. Our Sept. elec. bill (because of air conditioning) was not as high as previously during the summer. I believe it is drawing hot air from the entire attic of the house. And for sure our garage (on north side) is not unbearably hot.

    Rated 4 out of 5 by from 35316 works as designed I purchased a house where the two old gable fans no longer were operational. I found the 35316 on-line at Amazon.com and ordered two fans. My contractor installed them with light switches so I could manually turn them off without using the built-in thermostats. As it turns out, one of the fans failed to work when I turned it on. The contractor checked that there was power to the fan. I called Broan and they immediately sent me a new thermostat and motor. As it turned out, the original motor was defective - DOA, but the thermostat was OK. I unbolted the fan from the housing and disconnected the wiring and installed the replacement motor into the housing and reconnected the wiring. The customer service person was very helpful telling me that I needed about 4 square feet venting/fan for each fan to operate properly and that I should set the thermostat to about 30 degrees above the normal room temperature for each attic. This was very useful since the fan that was working was on all the time because I set the thermostat temperature too low at 80 degrees causing the fan to stay on all the time. Broan makes good stuff! My stove top exhaust fan is still in perfect condition after 50 years of service. I highly recommend Broan for the quality of their products and honoring their warranties.

    Does this fan have a thermostat so it will come on automatically? Is that is what is considered other controls?

    I am going to replace my exisiting solar attic fan # 3555SO with an electric fan. Can I swap the fans and install in the existing fan housing?

    Thank you for your question on the model 356BK. The solar and the electric attic fan lines are totally different sizes and parts are not interchangeable. Please feel free to contact the Technical Service department at 1-800-637-1453 with more questions.

    15 amp breaker

    I just installed this Gable fan in my garage and it keeps tripping my breaker. This is rated for 3.4 amps and there is only 1 light on the same line which is an LED light. The fan was running for several hours before it tripped the breaker. Now it trips the breaker the second it starts. I'm wondering if it could be a bad motor causing it to pull to much and tripping the breaker. Has anyone else had this issue?

    There is a problem with the thermostat which would not go on at 120 on an 80 degree day.

    Now it has been set on 110 degrees and it was 80 degrees today and it did not come on at all. My previous Broan fan would have come on and it was set at 120 degrees. What would you suggest that I do? Is the fan defective? Thank you.

    set the thermostat to 90 degrees if you want fan to run at 80 degrees you must set the thermostat to 80 and below
