Modern and modernised homes are designed or adapted to eliminate draughts and to retain heat inside the property. This reduces the free movement of air causing condensation which can often become a problem as moist air generated in the kitchen or bathroom cannot escape.
Common Fan and Exhaust Systems
Most exhaust systems consist of an exhaust fan, ducting and an exterior hood. Some houses have a central exhaust system, in which one fan draws moisture and odours from several rooms of the house using a network of ducts.
Inline Exhaust Fans: These are mounted in-between ducting and are typically used in places where you want to ventilate an area that does not have the clearance or space for a ceiling mounted fan. Since these are not mounted directly into the ceiling, they are typically very quiet.
Ceiling Mounted Exhaust Fans: These are some of the most popular fans and as the name indicates, they are installed in the ceiling.
Wall Mounted Fans: These are installed directly on the wall, creating a direct pathway for stale air to be expelled outside your home. For this reason, no ductwork is required to install these fans.
Combination Units: These come in a variety of combinations mixing the above fan varieties with additional features, including a fan-light combination and a heat-fan-light combination.
Bathroom Fans: What Should I Look For?
- The quietest – most energy – efficient fan in the size range required.Look for fans labelled “low noise” or “quiet,” and check for the HVI ( Home Ventilating Institute) rating.
- Low-resistance (smooth) exhaust ducting.
- The exhaust hood where it will not cause moisture damage on exterior surfaces.
Whatever kind of fan you choose based on your bathroom’s layout and structure, make sure that you select a quality fan so that you can rid your bathroom of harmful mold and mildew.
