Bests & Worsts Reviews from Amazon

Was going to go with one of the other Panasonics that had a higher CFM rating but then I stumbled across this one with the heater built in. I'm glad I did, and am happy I spent the extra 50 bucks. I did the install and electrical work myself. If you've never done much electrical you should really pay a professional. The junction box, as stated in other reviews, is very cramped in the corner of the unit. If you ran 14ga wire it would be easier to stuff the wires in there but you're really getting close to the limit with a 15amp circuit due to the heater. Remember circuits should only have an 80% continuous load, with 15a that's 1440 watts. With everything running on this bad boy you're drawing 1495 watts. Something like this really should be run on 12ga/20a. I made all the connections up in the attic with the unit upside down and with the switch leads extended through the knockouts farther than their final position. BTW I used metal screw type cable clamps and its not that hard to do if you have the unit upside down and have access to both inside and out. After you make all the connections the tough part is stuffing them into the box and pulling the cables through the knockouts to their final position for clamping. Could have used an extra hand for this. You may need to use some needlenose pliers to stuff each wirenut/wires down into the box. When all was done I flipped the unit back over and rested it into position on top of the drywall and secured the braces. I know the manual shows it being inserted from below.. and maybe I'm missing something, but the way the grille attaches with spring wires it will work either way, you'll just be able to see the cut edge of the drywall if you look closely through the grille. Working on this from below with the fan in it's final position would be a nightmare and leave you with a sore neck. A couple of words of caution that could save you some hassels.. for the main light I used the original circuit from my old fan and lights as I wanted the old vanity lights to work at the same time. For the night light I decided to just hard wire it ON to save myself from running another switch wire. 4W I don't really need it to switched.. If I leave for a long time I can trip the breaker. So I tapped onto another part of the original circuit where it branches off to power the lights in my kitchen. The problem with this is the both of these wires were on the load side of GFCI's and the light and nightlight circuits on the Panasonic share a common neutral... This will not cooperate with GFCIs because the current can return through either neutral and won't match up back at the GFCIs and will trip them. I solved the issue by putting these circuits on the line side of the GFCIs. After 3 hours I spent troublshooting I was cursing Panasonic for saving a few cents by using the shared neutral. There was no reason for those wires to be on the load side of the GFCI's but whoever wired them was just trying to save from using wire nuts and threw them on the load terminals. Can't say I blame them. With the night light hard wired 'on' I only needed 3 switches so I put in a 3 gang box and have one decora for the light, a Lutron countdown timer for the fan, and another regular 20a decora for the heater. I contemplated putting in a leviton countdown timer for the heater, which would be nice, but these seem to have a pretty high failure rate and I'm sure with a high current device attached the rate of failure is even higher. A trusty old switch will do. All said and done this is more expensive than the 3 rocker switch designed for this unit.. but it includes the timer switch for the fan which I think is a must. As for operation the lights are nice and bright. The fan works much better than my old unit; it is quiet, but not silent. Put it this way, with my old fan I could clearly hear it rumbling over the noise from the shower. With the Panasonic I can't hear it while I'm in the shower, but it's easy to hear otherwise. But hey, you know it's working. No fog on the mirror anymore, the heat helps with that too, though. The heater is GREAT. This is so nice as it's getting to be winter time and without it I would hate to turn the water off and start the dryoff process, that's always the coldest part. With the heater on this thing running you don't get cold AT ALL. You can also share a shower with your significant other, and you won't get cold when they're hogging the water. It's like being in a sauna... well, not that hot, but very comfortable. After towel drying I stand under the heater outlet, which conveniently aligns with the middle of my mirror, and that warm air drys you right off. Put it this way, my hair is cut pretty short right now, maybe 3/4 of an inch. I can stand under that blower and run my fingers through my hair for 30 seconds and it's completely dry. LOVE IT! In the end, my advice is to buy this, and do what you have to do to get it installed, and you will thank yourself every time you get out of the shower, and doubly so when it's winter time. update: If you're looking for an LED replacement night light bulb this one is awesome! Almost exact color temperature and just as bright if not brighter.. .36 watts makes hard wiring the night light on even more practical. http://www.amazon.com/G7-Power-Beatty-0-36-Watt-Replacement/dp/B007O0OFFA/ref=cm_cr-mr-title
