It's odd that you can't see the image I linked to; it shows up fine when I load this page. Anyway, yes, the MA-L3T251 is the one I was referring to. I'm sure this is fine with any light and fan, but if the timer is going to control a heater, you need to find out what the power draw for the heater on that Panasonic unit is. Because this switch combines a dimmer and a timer in the space of one switch, it is limited to 300 watts of power (whereas most switches and dimmers are typically rated for 600 watts, and some even for 1,000 watts). A heater typically draws a lot more power than a light or a fan. You might be fine with this, Susan, but I was suggesting you check the power so you don't end up disappointed with a burned out switch after a short time. I would think Panasonic should be able to tell you how many watts the heater draws. (If you get a number in amps, that's just as useful. Multiple amps by 120 volts to get watts. So: this switch is rated at 2.5 amps x 120 volts = 300 watts.) -- Eric

Thull makes a good point - the heater fan is noisier than the exhaust fan on the WhisperWarm. I have both the Whisperwarm and the BOL smallest fan. Both are solid performers and unlike the Nutone crap they replaced in 2003, they have remained very quiet. The WW is definitely louder than the much smaller 70cfm exhaust-only unit, but if I walked outside the bathroom into the master bedrm, I can't tell it's on. The WW needs 4 switches: heat, exhaust, big light, small nightlight. You can combine some functions or just eliminate them. We didn't need the big light, for example, and only had 2 switches available. So we combined the exhaust with the night light, and have the heat on separate switch. Our 13x7' master bath is the coldest room in the house - we live in coastal Northern CA, so altho it doesn't freeze often it can get windy, rainy and cold - and the Panasonic WW works far better than the idiot infrared bulb that was almost totally useless unless left on for hours and hours....! If you have a large bathroom, I'd get two rather than trying to overwork a single WW unit. They are big, but we had no trouble with it fitting between the joists in the ceiling when we replaced the Nutone. The smaller Panasonic in the main floor bathroom is so quiet, it's often left on accidentally because even inside the bathroom, it's barely audible. The WW in the master, when you put the exhaust on, is louder but still quiet compared to the Nutone it replaced - not at all obtrusive or objectionable.

I have installed Panasonic fans in both of my bathrooms. They are both smaller than yours and I calcuated I needed fans which could support 150 CFM of air flow. The FV-11VHL2 is rated for 110 CFM. In my opinion it is too small for a 14 x 12 bathroom. Unfortunately this is the largest in the Whisper Warm line. You would have to drop the warm feature if you go to a bigger fan. Do a search on line for the Panasonic fan size calculator. Some sites are easier to follow than others. You could put a second fan in the toilet area, but then you would have to turn on both fans to remove the moisture after a bath or shower. The fan size is not critical. Having good air flow will help reduce moisture and mold problems.

I have a Panasonic Whisper Quiet. I am not sure what level of quiet you are expecting. When the fan is on I can definitely hear it but it isn't loud or annoying. It just registers if the room is silent and I am not doing anything. It is a very low sound - almost equivalent to white noise. My fan turns on and off based on ambient moisture levels so in general it doesn't run that much. It runs briefly after someone takes a shower but other than that it isn't on.
