    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.

    Rated 4 out of 5 by 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! May 30, 2016
    Rated 5 out of 5 by Nice product I would use this seller again. excellent service. fast shipping. November 1, 2014
    Rated 5 out of 5 by Broan 358 attic fan. Great product I ordered this attic fan in August. I had a new roof put on and the roofers installed it for me. I am very pleased with the job it does pulling the hot air out of the attic. A friend told me about the attic fans, i am sorry i didn't put one in sooner. September 12, 2014
    Rated 5 out of 5 by product name replaced old fan 25 + years old so far so good works as expected if it lasts 25 years I will be happy September 5, 2014
    Rated 4 out of 5 by 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. July 20, 2014
    Rated 5 out of 5 by The attic fan has great features The instructions are helpful and make for an enjoyable install. I am wiring in the thermostat bypass and fan motor switches. I am looking forward to the first summer with an attic fan and expecting the house to be more comfortable. April 29, 2014
    Rated 1 out of 5 by The 35316 exhibits a horrible vibration that shakes the entire house. Great potential if only the fan was balanced at the factory. Vibration is horrible. April 23, 2014
    Rated 5 out of 5 by Easy to install and relatively quiet This power ventilator is rather easy to install on a cool day. A cool day is easier on the installer and on the shingles. This ventilator was installed in the early spring with the temperature setting on about 100. As a consequence, it did not operate until several months later. One evening I noted a noise on the roof and sure enough the power ventilator was operating as it should. Later in the evening it was OFF. As it is now March 2014, the unit is OFF and very quiet.

    We have sealed and conditioned attic that I want to ventilate periodically using a switch or timer. The attic stays cool so the thermostat would likely not cause it to come on often.

    Maintenance for 356-G?

    Customer avatar
    by
    matlinp
    Baltimore, MD, USA
     on 356BK
    I have a 356-G attic fan which was installed a number of years ago. I'm now detecting a strange noise from that area of the attic - like power is being applied to the fan, but nothing is moving. This lasts for maybe 10 seconds, dying out over the duration of the incident. Recurs every 5-10 minutes, when the fan is off. I haven't as yet climbed up into the attic, but I don't see any information concerning maintenance in the installation manual. I'm sure that there is dust buildup over time, etc. What are the recommended user maintenance procedures, if any?
