In this video, This Old House host Kevin O'Connor works with a professional electrician to install a ventilation fan in a bathroom. (See below for a shopping list and tools.)
SUBSCRIBE to This Old House: bit.ly/SubscribeThisOldHouse
Kevin O'Connor and electrician Brian Bergeron helped a homeowner install a new fan in her bathroom. The fan exhausts the humid air created by the shower to the outside of the house. Brian determined that the easiest way to power the fan was to use the electricity from an existing light switch. With the power shut off, he disconnected the light switch. Next, he enlarged the hole in the wall so he could make the existing electrical box bigger to accommodate a separate switch for the fan. Up in the attic, Brian and Kevin drilled a hole through the top of the wall and "fished" new wire for the fan down to the switch box. Downstairs, Brian connected the wire to the new fan switch, which has a built-in timer. Next, Brian cut a hole in the ceiling between two joists and fastened the fan in place. Then, he connected the new wire to the junction box on the fan. Finally, he cut a hole through an exterior wall and installed a louvered vent on the outside. He then installed flexible ducting between the fan and the wall. Later, up in the loft, Tom recommended that for colder climates, it's a good idea to use insulated ducting to prevent condensation inside the duct.

Vent flex pipe should have insulation wrapped around it from fan housing to connection for outside vent. Cold attic and warm moist air going up from the bathroom fan when showering up through the pipe will cause condensation, over time will drip and soak attic insulation will cause mold & mildew over time Also NEVER WRAP REGULAR DUCT TAPE AT CONNECTIONS, USE ALUMIUM TAPE. I also like to use hose clamps after wrapping tape around the connections. DO NOT over tighten hose clamps, just make them snug.

This fan works very well. kzfaq.infoUgkx7yWIKcrbA9KMHkGSfcgxW2lsjHT6B8Sh I replaced my old fan as our radon levels began to spike. When I remove the old fan water poured out of the fan. Must have entered in through the out spout. Replaced with this unit and levels dropped a bit but still over 4.0.Did some more digging and found that we had a small hole under our waste pipe that was allowing some water and radon in.Patched the hole and the levels dropped almost overnight.I really would recommend the radon sensor. It gives real time readings. Without it we would have never known that we had this issue.

Everyone the above comment is correct about aluminum foil tape! That is the tape you should be using with duct work. Duct tape is cloth based and it will dry rot and loose adhesion and come loose over time. I verified this with a friend who is an HVAC contractor and he said all you are suppose to use is aluminum foil tape or duct putty. I have even seen the end results of someone using duct tape to seal duct work in my own house. We purchased a house where the HVAC ducts were sealed in the above manner and most of the tape was dried out and failing. So, I had to tear all that old tape off and get a bucket of duct putty from my friend and paint the joints to seal them correctly.

To go thru roof is way more trouble than a side wall vent. Plus increased chance of a leak. Ideally if you have a ( Y ) duct split. In. The exhaust vent line somewhere about midway of the entire run you would have an excellent exhausting system. But who wants to cut a hole in the roof and in the side wall to vent air from the washroom. I seldom see contractors do things exactly the same way. There's always thing's done a bit differently between contractors. It's just that each person thinks that their way is better.

There were a lot of important steps you missed. For instance, check with your local municipality if you need a permit.

Third, blue duct tape instead of foil tape? Fourth, non insulated duct in an attic? Fifth, he totally skipped over the wiring of that box. He bypasses the light switch in the instruction and then shows it magically with the switch at the end, which meant he rewired it off camera...

Hello, When we had our roof replaced a year ago, I had the roofers install goose neck roof cap vents over the bathrooms with plans to install exhaust fans. Problem is, I wasn't specific with installing the type that allows you to attached duct work to it. So it's a square whole like a standard vent to air out the attic. It would cost $800 to get both exhaust vents replaced. I've been told by several folks (even AC contractor) that this actually common and people either just shove the duct work inside the vent OR they use duct board a trunk line to seal and create something the duct work can attach to. I'd rather do it that way otherwise the roofers would have to tear out the vent they installed and install a new one and that's an additional cost. Any suggestions?

Foil tape, not blue duct tape (rated for cold my ass). Duct should go straight up through the roof if possible. As few bends as possible. Certainly shouldn't be venting horizontal to the intake.

In cold weather applications moisture condenses and guess what happens when you have vertical exhaust ducts? That condensation runs back down when the fan is not operating. This isnt rocket science gents.

@samamorgan 6 жыл бұрын

Your recommendations go against most fan manufacturers instructions. Every fan I've installed in the past 10 years has a horizontal, slightly downward angled initial run so that there's a drip loop by default. This eliminates any possibilities of water re-entering the living space. Not that there should be any condensation left in the ducting if the fan is being used properly with a timer. The best possible place to vent is always the shortest possible run to the outside, considering where the warm moist air will end up as it rises. In this case, the roof is the obvious best choice, as running the additional 10-15 feet of duct as seen in this video significantly increases drag, making the fan less efficient. Using a short run directly out the roof decreases the surface area that the moist air will come in contact with, which of course reduces drag and the amount of condensation that can build up in the first place. Also, thanks for the childish name-calling. You seem like an extremely professional individual.

Sam Morgan in Canada, we have over 2feet snow on the roof in winter, I installed my bathroom fan through the gable wall, going through the roof is not recommended here.

I prefer to use 3M metal foil tape so I can slice the living hell out of my fingers when smoothing it on the duct joint. But I enjoy pain...

Save your fingers and get a tape smoother! After using one of these on metal tape, you'll never go back! And the real bonus is that it pushes out all of the air bubbles and is a bear to peel it off. www.bakerdist.com/avery-dennison-adsq50-tape-squeeze-scrapper-tape-smoother--3ff5809

Right on. Should have put it through the roof and put an insulation jacket around the duct.

@crdrewerts8967 6 жыл бұрын

Again. If you run bathroom exhaust ducts vertical moisture and condensation will run straight back down dripping right back into the bathroom. Horizontal ducting is SOP for this set up in cold climate. The minor condensation that builds up in the pipe will evaporate.

If you look carefully you'll see a screw inside in the bottom. Instead of going from the outside in (through the hole then threaded hole) he screwed from the inside out (through threaded hole then the regular hole). Best it'll do is hold it where it needs to be but it will be floppy.
