It is possible to vent your bathroom fan through the soffit and avoid making a hole in the roof. Usually, a hole in the roof may lead to leaks and other problems. Sometimes it can be difficult to vent a second-story bathroom to the sidewall.
Whether it's new construction or a remodel, a bathroom vent should always vent through the roof instead of an eave, overhang, or soffit. The point of a bathroom exhaust vent, or any vent really, is to remove hot, moist air from the house.
The fan exhaust must vent directly to the exterior of the home. Do not put the vent termination in a roof overhang or soffit. Don't put it on a wall near or under a roof overhang. The moist air that's belched out by the fan can be sucked right up into the open soffit vents and be drawn into your attic.
No, you cannot vent your bathroom exhaust fan into the attic. You should never exhaust the bathroom fan directly into the attic. Your attic is not a temperature-controlled environment, is never the same temperature as your living space and generally closer to the temperature outside.
You must not vent into the soffits, or even under the soffits unless you are more than a foot and a half below the soffit to allow the wind to dissipate the moisture before it rises back up into the attic.
Run the duct straight out the side of the soffit by cutting a duct-sized hole with a saw. If you need to angle the vent down toward the ground through an overhang, cut a hole in the overhang and connect the horizontal duct to a vertical duct using another adjustable elbow duct or a transition fitting.
No, you should never vent your range hood into the attic. The excess buildup of grease and moisture in your attic will ruin it and over time may cause mold damage. Instead, vent your hood through an interior wall or through the ceiling all the way outside of your home.
Installing a ceiling vent is probably the most efficient way to ventilate a bathroom with no outside access. A ceiling vent is a unique machine that allows air to escape from the bathroom. In other words, it's a machine that, like an open window, allows moisture to escape from your bathroom.
The answer is no way! Sewer gas is explosive and could settle back into your exhaust fan which has an electric motor that is not rated for explosive gases. You're now not at code for the sewer or the fan.
Bathroom fan installation requires outside ventilation. If the fan isn't accessible through an attic, you'll need to vent through a sidewall of your house. These types of ducts and vents are typically installed when the house is built.
Yes, you can install the fan yourself. Installing a through-the-wall fan is not as difficult as it sounds. Sure, there's the fan type, the power source, the vents, the cutting, and much more to think of.
Well, you can't! You'd often blow air from one bathroom into the other, and local building inspectors wouldn't approve it. But while you can't have two fans with one vent, you can make one fan and one vent serve two bathrooms.
The Code of Bathroom Exhaust Fans
– Air shall not be exhausted into an attic (except whole house ventilation), soffit, ridge vent or crawl space.
I'd seriously consider using foam core PVC pipe as the vent pipe for your fan. The fittings can be glued, and any water that might form in the pipe will never leak onto your ceiling or down a wall.
While the law doesn't state you must install an extractor fan in your bathroom, it is illegal not to have a source of ventilation inside. This will depend on the structural make-up of your home, but if there is no openable window in place, then an extractor fan must be installed.
A ductless fan removes excess moisture from the bathroom air by passing air through a filter that draws moisture from the air. This humidity control function is critical to keeping your bathroom fresh and your furniture in tip-top shape.
Typically, these fans work by processing the air so that they can remove the odors easily and quickly. The fans rely on an activated charcoal filter that is capable of making sure the air is fresh. The filter helps to circulate air throughout the whole room; hence, removing any smell from it.
Range hoods do not have to be vented to the outside. You can purchase hoods without ductwork called ductless hoods. But, ducted range hoods are almost always preferred over ductless hoods.
Microwaves cannot be ducted into a common duct work. DO NOT vent into an attic or crawl space.
There is no requirement that your Over The Range (OTR) Microwave be vented to the outdoors. All OTR microwave ovens can be set up to either allow the fan to recirculate the air back into the kitchen or be vented to the outdoors.
The gable vents turn into intake vents and bring in warmer air to the attic space. Some attic fans or whole-house fans are too powerful for the attic. If the negative pressure they create by exhausting attic air is strong enough, they can draw conditioned air from your living space into your attic, and then outside.
Both wall and under cabinet range hoods can be vented on an interior wall. Venting a range hood on an interior wall may seem daunting. But, if you are comfortable DIYing it, you can save money doing the installation yourself. If not, we recommend hiring a local contractor to install the hood.
The fan's exhaust must be vented to the outside. It is possible to position the fan on an outside wall and vent it through the wall to the outside, but if the fan and connecting duct are not insulated properly, moisture will seep into the wall cavity and lead to rot and structural damage.
