When renovating or building your new home, you will find yourself coming across many components that we take for granted in our daily lives. One of these are exhaust fans. Many people ask us what they are and why they’re needed. Let’s discuss what an exhaust fan is, what they do and why you need an exhaust fan in your home!
What is a Ceiling Exhaust Fan?
A ceiling exhaust fan is a small, fan that is mounted into a ceiling. It works to expel air upward through the ceiling and can be exhausted into the roof cavity or ducted outside. This allows fresh air to enter from elsewhere (a door, window or vent). The warm air that has been extracted is drawn outside. You can find exhaust fans in kitchens, laundries and bathrooms.
Why Do I Need an Exhaust Fan?
In our homes, bathrooms, laundries and kitchens are prone to moisture problems, caused by the high humidity of these zones. Every time you use hot water in your home, you create steam. That steam penetrates every crevice of the room and then cools down. As it cools, this steam turns into water, which then turns into condensation. Condensation, in turn, feeds mould, mildew and, in extreme cases, structural rot.
Not only that, but it can cause damage to fixtures and surfaces in a room. The growth of mould or mildew can cause a musty smell to build up in the room.
Exhaust fans also help expel any potentially unpleasant odours that may form. Bathrooms, in particular, need a good ventilation system to expel air before it turns into condensation.
What is a 3-in-1 Exhaust Fan?
Many ceiling mounted exhaust fans also come with a lighting and heating system. They are popular in bathrooms as they save space, so you won’t need to crowd your bathroom with a range of appliances. 3-in-1 exhaust fans come in a wide range of configurations, including multiple lights, multiple heat lamps, and even remote control options.
Do I Always Need to Use My Fan?
Many customers are confused as to when exactly they should use their bathroom exhaust fan. Others claim that you only need to your fan in summer. This is due to the fact many confuse their exhaust fan with a pedestal fan that cools during the summer.
When you have a shower or run a bath, the hot water increases the humidity in the room. As the humidity rises, so does the level of condensation. And, as we said earlier, condensation promotes the growth of mould and mildew. So you should always run your bathroom exhaust fan when showering, no matter the time of year.
Should I Use My Bathroom Exhaust in Winter?
Further, you need to be careful not to add moisture to your home during winter. This can cause damage not just in the bathroom or other wet areas, but also in other areas of the home.
Another reason to ensure you run your fan, is due to the fact it is part of your overall home ventilation system. You don’t want to turn it off in winter, as this can compromise the entire home’s ventilation system.
