![]() ![]() ![]() For this, you must calculate the room’s length, width, and height in meters and multiply them together.įor example, if the room is 2m wide, 3m long, and has a height of 3m, then the size would be 18m 3 (2 x 3 x 3 = 18). Once you have a clear idea about the number of air changes required, you must measure the size of your bathroom. Bathroom with a shower – 15 to 25 times.As a standard, these are the typical number of air changes required for different types of bathrooms and toilets. The number of air changes required in the bathroom will depend on the number of equipment in your bathroom. The number of air changes means the number of times all the air in the room is replaced with new air. The extended ducts will expel the air to the outside through an opening on the wall or the roof. These exhaust fans are also ideal when there is not enough roof clearance for ceiling exhaust fans. While the inline exhaust fans are less noisy when compared to the ceiling fans, a single fan can serve more than one bathroom at a time. These fans are usually in a remote location and connect to a duct that ends in a grille that opens into the bathroom. The inline exhaust fans are usually placed directly on a ceiling cavity and mounted in-between the lengths of a duct. Since window exhaust fans expel air directly to the outside, there is no need for a duct. This provides a weatherproof shield while the exhaust fans pull the air directly to the outside. Basically, window exhaust fans have two parts, which must be sandwiched together through a hole in the window’s glass. Window exhaust fans are generally used in apartments and places with limited roof space. Therefore this eliminates the need for long ducts. The wall exhaust fans will be installed on a wall that opens directly to the outside. This is ideal when there is not enough space on the ceiling to install the ducts. These are the exhaust fans that are mounted on the walls of the bathroom. If the distance is too long, then the exhaust fans’ effectiveness will be minimal. On the other hand, when installing ducts, ensure it has the shortest distance from the fan to the outside. Therefore if you leave the vents in the attic, it could get heated and accumulate moisture which could lead to a whole set of new problems. This is since your attic is not a temperature-controlled location. However, getting them out outside the home is always better. Most individuals tend to vent the ceiling exhaust fans into the attic. These fans will carry the air upwards through the ducts to the outside. Ceiling exhaust fans are the most preferred among most householders. Ceiling exhaust fansĪs the name suggests, ceiling exhaust fans are mounted on the house’s roof. Also be aware that aluminum (rather than copper) wiring requires special handling and any electrical work involving this type of wiring should be undertaken by a professional.There are basically four types of exhaust fans which you could choose depending on your bathroom’s configurations.If you don't feel confident about doing the wiring yourself, don't hesitate to call in a licensed electrician to install the fan or simply inspect your work when you're done.Place the wires back in the electrical splice unit and reattach the cover.Wrap the bare copper wire around the green grounding clip or screw and tighten to secure. Twist the same color wires together (usually white to white and black or red to black) and add the connectors.Strip 5⁄ 8 inch (1.6 cm) back from each of the wires on both the fan cable and the electrical cable you inserted earlier. Open up the housing unit and pull out the fan wires from the electrical splice unit.Make sure to read the manufacturer's instructions and double check that the power is off before proceeding. ![]() ![]() Depending on the type of fan, you may need to wire the connections from the attic or from the bathroom. Wire the connections in the housing unit. ![]()
