Question: Is there enough room inside to install a compact fluorescent light bulb instead of fluorescent?
Document: My family loves this heater/fan/light unit. The nightlight gives off just the perfect amount of light for those nighttime visits (enough light to see but not too bright so it wakes you up completely). The nightlight is also on 24/7 so you don't have to worry about turning it on/off. The fan is powerful without making a lot of noise and has a timer function (five minutes is more than enough to clear the room of fog after a shower).
This unit comes with its own wall switch: two rocker switches that control all four elements (light, night light, heater, and vent). Not needing the night light feature, at all, I decided to buy a separate Nutone switchBroan-Nutone P66W Fan Control Switch. The 3 unit switch works just fine.The unit is heavy enough that it will get a bit tiresome installing it, but it's very sturdy overall.
The heater is very functional and puts out a lot of heat from the ceiling. At first I was was concerned it would not heat as much as a floor heater - no problem. It is fairly quiet for it's output but would not win first prize. The vent and fan are about even in their noise. The nite lite feature designed for the old pre fluorescent days is a little silly as it only has space for a 7 watt small incandescent which draws 50% of a fluorescent bulb likely used.
Got this to replace a 1960's era ceiling heater and it works exceptionally well. Install it will require knowledge of wiring as it's got a 4 function switch, but it still only requires a standard receptacle, so it can easily replace an older unit.
If you already own one of these and it gives out, feel free to order this. Literally takes 10 minutes to pop out the old and replace with the new. Remove a few screws and you're good to go. Can't comment on completely new install, but as replacement for an existing one, it's great.
You can choose the temperature you wish to heat your room to and it will cycle on and off to maintain that temperature. No more freezing in the bathroom shower on those chilly mornings!This is the second unit that we've purchased; the first purchase was made 10 years ago. We love the first one so much we put another one in our second bathroom as we were remodeling.
As I mentioned earlier, the fan is powerful and it pulls a lot of dust though whenever you turn it on and some of the dust sticks to the interior components (most of it blows outside). You must vacuum the dust out regularly or it will blow back into the room when you turn on the heater. The cover comes off easily and it only takes 30 seconds to vacuum all the dust out. If you maintain the unit correctly it will last for years.
This a replacement for the old unit in our master bath. I purchased it so we wouldn't have to repair/re-plaster the ceiling, I love having heat, lite, nite light and fan all in one
We have used this fan before. And this iteration fit in the hole and the wiring perfectly. The only change in this fan, heater, light is that the rim isn't chrome but white plastic. At least it works. It's the only fan and heater in the upstairs.
Don't get me wrong...this heater/fan/light/nightlight is great! We had one original to our 1978 house and it lasted over thrirty years. we even used the same cieling mount. The hole was the same size so that was wonderful.
Answer: yes
