Product Details

This bulb heater/fan provides silent warmth and superior ventilation in a compact package. It helps eliminate steam and odors. The heat and ventilation functions may be controlled separately or in combination. The low-profile grille blends into most ceilings. The 70 CFM fan provides excellent ventilation at a quiet 3.5 sones. The quiet, highly efficient polymeric blower wheels maintain consistent power, while the polymeric dampers prevent backdrafts and eliminate mechanical noise. Additional features include a sturdy steel housing, a plug-in, permanently lubricated motor, adjustable mounting brackets with keyhole slots, and a 4" round duct connector. Use 250W BR40-size infrared bulbs (available separately) for comfortable heating performance. Operate the fan with a choice of wall controls, available separately.

Note: Ceiling heaters are intended to provide supplemental heat and not to take the place of the home’s main heat source.

14-1/4 In x 8-3/8 In x 6-3/8 In Bathroom Fan, 70 CFM, 4.5 Amps is rated 2.7 out of 5 by 14.
Rated 4 out of 5 by from So far so good! I purchased this model to replace an older version in my bathroom. My electrician suggested replacing my old model with the same brand and make for the easiest installation. I am pleased with the fan performance and like the heat lamp for winter use. I would recommend this product.

Rated 3 out of 5 by from A good unit, noisy, but effective Unit was installed by a contractor on a total bathroom re-mo. It works fine as a fan and as a heat lite, but is noisy! I've been under 'the quiet ones' and there's a big difference, but none of the 'quiet ones' come with heat lamp sockets so it is what it is. I just went thru a replacement of the temp sensor on the lites. The contractor didn't wire it so the fan had to be on if the lites were on. So it got turned on without the fan and poof, out went the sensor. Only available online and not too hard to change if you have elec. experience, but not for the amateur.. It's now wired so the lites won't come on unless the fan is on. It's very odd the product label on the inside doesn't state the 'max' lite wattage, I had to go online to look it up. It's also odd the label says to use a15 amp circuit, it seems like it should be 20 amps which is what I do have. If 'another day' Broan re-designs this thing they need to strive for "quiet". That's the only reason I rate it as "average".

Rated 2 out of 5 by from Thermo fuse Installed a model 164 for a customer. I am back In the attic a few weeks later and determined the thermo fuse blew. Why did it blow? It appears other customers had same problem.

Rated 5 out of 5 by from 4 164A-C units installed in my house in 1983. All still working perfectly. Fans are getting a little noisy, but still work perfectly. Have worn out numerous,numerous bulbs. They don't have the most modern look, but I took the covers off and painted them to match the ceilings.

Rated 1 out of 5 by from Poor Quality I like many of the comments made have the 164 and the lights have stopped working after a month! How do you fix? I am an licensed architect and would not specify this or any Broan product!

Rated 1 out of 5 by from Fourth Person to Discover Same Defect I'm the fourth person writing in to report that, after initially working, the lights stopped working (fan still works). I've checked out the power, and that is not the problem. I did a continuity test on the wires, and even with bulbs in place continuity in the wiring in the box does not exist for the two lights. I bought a second identical fixture, and the continuity check worked for this fixture. So, the problem is internal to the fixture and occurs after the fixture has been used for several weeks. OK Broan - there's a common problem with your two-bulb heater/fan (model 164), AND YOU SHOULD FIGURE OUT WHAT IT IS AND TELL US HOW TO CORRECT IT.Three other reviews:"This product worked fine but now the lights have quit working" (rcorwin) … I have only used this unit for a couple of hours and now the lights do not work. The fan works but nothing else.""Extremely poor wiring and eventual problems (Wi4x4Man) … "It worked for about 1 week when suddenly both lights quit working but the fan still worked. The switches for the heat lamp and the light were providing power, and instead it was in the fixture itself.""It quit working (Allen)… "After one week of use, the lights stopped lighting. Doing some debugging I find that the current to the lights is too low and will not light the 2- 250 watt bulbs. Fan works on one switch and somehow the low current is also trying to run the fan. "

Rated 4 out of 5 by from Great unit for the price It was relatively easy to install. The wireing diagram could be improved but I got through ok and I'm not an electrician. I replaced one that was similar. This is quieter

Rated 1 out of 5 by from This product worked fine but now the lights have quit working. I have the same problem as Allen and wi4x4man. This product was wired correctly, took the electrian some time to figure it out. Could definitely use some longer wires.I have only used this unit for a couple of hours and now the lights do not work. The fan works but nothing else.I am troubleshooting it right now. I went to the Broan website to see if there were any troubleshooting pages.
