As long as the bathroom fan runs, the heat and humidity are easily controlled. To make the best out of your bathroom fan, you need to make sure the vent is positioned directly outside, secured with a hood cover.
The hood of the vent should be equipped with a flap. This flap will usually remain shut so that no dust can enter. However, it will remain open when air is blowing through it. The flap is an absolute necessity. It also prevents birds from nesting in the venting system. The first thing homeowners should consider is the CFM rating printed on the back of the fan. All bathroom fans are rated on the cubic feet of air they can mobilize in a minute. This value will vary depending on the area that needs ventilation.
Depending on this, the bathroom fan which best fits your requirements can be easily selected. Most bathroom fans range from CFM, although some are specifically designed for larger areas and have greater CFM values. The most radical mistake one could make while venting bathroom fans is by allowing them to vent inside the house. This is most common when these fans are allowed to vent into the attic.
Your venting system is causing mold damage to your walls and your roof. If this is the case, you need to get ready for some heavy-duty repairs. Another frequent mistake encountered with venting systems is not paying attention to leaks. If your fan vent has leaks, then sadly, it is not going to work very efficiently. Additionally, these leaks are letting hot, humid air leak inside your home, ultimately defeating the purpose of the ventilation you are trying to achieve.
An incorrectly installed hood cover can also send you down a rabbit hole of problems. It is crucial to ensure your hood cover is appropriately sealed. If not done correctly, the dust build-up will potentially cause choking in various points of your ventilation system. One lesser-known factor that contributes to molding is the use of the wrong duct system. Ideally, an insulated duct system should be used.
Using an uninsulated duct system increases the odds of condensation occurring in winters. It is always recommended to evaluate what duct system works best for your home.
Installation of a bathroom fan through a gable and creating an efficient venting system is a rather complex task. One that requires creativity and a good knowledge of how ventilation systems work since all homes are different and there is no one size fits all. Every venting system has two basic types of vents: register vents and return vents. Register vents remove stagnant indoor air, while return vents draw in fresh outdoor air.
Both types of vents are equipped with covers specifically designed to ensure optimum airflow. These covers come in various designs and colors and are made from multiple materials, from polished wood to light aluminum.
Some even have the added functionality of maintaining indoor air quality by removing impurities. Vent covers require maintenance annually. However, in some localities, more frequent sessions may be necessary depending upon the level of built-up. I can feel some water around the metal wrapping of the vent where there is an opening. Would anyone recommend wrapping a towel around this area to absorb the condensation and then switch the towel out monthly or so?
Feedback on several of the questions: 1. No, you cannot tie the bathroom exhaust to the hot water vent. That is a recipe for disaster and may very well not be to code. Two bathroom exhausts should not be tied to one vent.
They should vent separately. They will never vent properly otherwise. Each bend in the duct run reduces the effective distance max. You should call the manufacturer to find out their recommended vent distance. The long run is likely the cause of the water damage. Insulating the duct may also help. You may have a bad boot around the roof vent that is leaking into the attic. Or you may have a distance issue.
See comment 3 above. I have a bathroom exhaust fan that is vented directly into the attic. It has started to leak water back through the exhaust fan into the bathroom. What is the best thing to do to correct this problem. If you take it through the roof, using a metal pipe, do you use insulation around the pipe?
I have installed an electric extract fan in an inside bathroom however the council inspector has told me I require an air intake due to lack of air flow through hallway if doors are closed My options appear to be A Change the existing ceiling fan B Provide a separate vent to the vented ridge tiles C Provide a separate vent to the attic space. Since it would be uneconomical and too long to run an exhaust duct route from the basement through 2 stories and roof, so how do you feel about us running the exhaust duct horizontally by 10 feet along the basement ceiling to CMU block wall?
We think if you use the proper-sized pipe as recommended by the manufacturer of the exhaust fan, it should work great. I see many questions about leaking bath exhaust vents. I recommend replacing the vent pipe with insulated vent pipe.
Next, make sure it is securely fastened on both ends of the pipe. Next, make sure you have one of the new roof exhaust vents on the roof and properly sealed. Hi, Stephen! You might check to see if the fan has a damper flap; this piece is lightweight but can help prevent a draft from entering your bathroom.
Good luck! During heavy rain, water comes out of the exhaust fan in my first floor bathroom. We have a story and a half Cape Cod style house. How do I fix this? Thank you. Hi, Phil! It sounds like you need more insulation. Would it be better for the building if I stopped using the exhaust fan, and just opened the window when necessary? A bathroom exhaust fan removes moist air from the bathroom. The fan does this quickly and safely within 20 minutes of turning it on.
You could achieve the same result by opening a window, but the process could take much longer. Got my roof repaired after water leaks caused by blown shingles and I am very happy with the small repair work done the next day.
