An heat extraction fan is useful for many purposes. They can be installed in any room that has a problem with humidity, gasses or smoke. They are usually easy to fit into a pre-drilled hole in the wall, and some models can be fitted into a window pane.
Humidity Control
The main room where heat extraction fan are installed is the bathroom and laundry. Many people struggle with mold and mildew caused by steam and constant humidity. There are many products that can temporarily remove mold and mildew, but it will still continue to grow and breed if you don't take care of the base cause.
A small exhaust fan mounted in the ceiling or high on a wall will pull the moist air out of the room and leave the air too dry for mold spores to grow. Installing one of these fans is easy for a home handyman, or hire a handyman to do it for you. There are even heat extraction fan mounted in bathroom light fixtures, which is a great way to hide the fan.
A damp cellar can also be helped with an extraction fan, vented out through the wall.
Controlling Steam, Fumes and Odors
A stove hood heat extraction fan removes the steam, odors and smoke resulting from cooking. These fans help limit smoke damage to walls and ceilings directly above a stove top. Mounted over the stove, these hoods can be vented or ventless.
By removing smoke and steam from cooking, they also remove the grease that rises in the steam, eliminating the need to wash your walls around the cooking area.
Gas and Smoke Removal
Some areas that accumulate harmful airborne pollutants benefit highly from having anheat extraction fan installed. These can include basements where old gas appliances are used, and living areas where people who smoke gather. Extraction fan can also be useful in garages and workshops where dust producing equipment is used.
Heat Removal
In hot climates, an heat extraction fan can have a second use as a heat removal tool. Usually heat rises and pools around the ceiling, so a fan can pull that heat into the roof space, creating a continual flow of cooler air into the room.
Maintaining Wall and Fabric Health
This is most important in areas where people smoke. The tars in smoke slowly build up and a thin layer develops on walls, windows and furniture. Extracting the smoke stops this process and keeps your furniture and walls clean for much longer. You only have to wash the windows in a typical smoker's home to see the effects of cigarette tar build-up.
When installing an extraction fan in the ceiling, be careful of the insulation and don't cover the box with insulation when you're finished. Most ceiling fans will vent into the roof space, but some will require duct hosing to the outside. You will have to choose which will do the job you require, and think about the ease of instillation.
