Re: Add second bathroom fan vs. install bigger one?


I think 70 isn't enough because the bathroom is very steamy for a long time after a shower (an hour?). That's a pretty general statement so I'll add that it's much steamier for much longer than any other bathroom I can recall having showered in.

Installing a timer might be problematic: the fan is within a can light unit that's controlled by one switch, so the timer would also leave the light on/turn it off at potentially inconvenient times.

Thanks!

Your bathroom will stay wet with any size fan if you shut the fan right after showering. There's a lot of water to evaporate from shower or tub surfaces.

The fan should be really be on a separate switch.

If not you can actually do two light switches for the fan/light both feeding the same hot; one a switch, and the second one being a timer.

If you use led bulb, the extra electricity use of running for an extra 15 minutes will be minimal.

Re: Add second bathroom fan vs. install bigger one?


I have 2 lights in my bathroom. One is the vent vent fan/light combination. The other is the light over the sink.

The vanity light is slaved off the vent fan light. I'm also using a motion sensor for the vent fan. (the people on my house have not figured out how to turn off lights)

Hence, when you go in the bathroom....you turn on the light....that turns on the fan...but it's quiet enough you don't notice it.

Start with a Leviton 6260M-W push button timer.
Turn it on when you get in the shower. Also when you get out you can press it again for 10 or 20 minutes since that is how long it is recommended to fan a fan after you have finished a shower. It is important to also run it after.
Light or no steam press 10 min or heavy steam press 20 min and walk away.

Next , two fans are a bad idea for a few reasons and could work against each other sometimes.

So you a new higher cfm fan. Or I really like the very quiet Panasonic inline fans.
You could leave the current fan and add the inline fan any place in the ductwork.
Then with your current fan you can remove the cover and see the motor and the plug for it.
You will then have the option to just unplug this motor since the panasonic will be pretty powerful.
Or another option if you wanted, is to leave it to add extra cfm's as a boster fan.
Either way it should take only a couple of minutes and you can play with it and decide which is best for you.

Is the current 70cfm actually working? Don't assume it is because the motor makes noise. A 70 cfm fan will clear the 1000cf room in 14 minutes, if all things are correct.
