A bathroom heater fan will keep you warm and toasty in an unheated bathroom; however, you must take certain precautions to ensure your safety.
Some heaters have a long cord that can get tangled up in your feet, causing you to trip. Avoid this hazard by purchasing a heater fan that mounts over an electrical outlet without a cord.
Some heater fans are designed to shut off on their own once they have reached the maximum temperature. This thermostat creates a safer environment because you won't mistakenly leave the house with the heater running. Other models are designed to automatically turn off when the fan becomes blocked or if the heater tips over.
Protective Outer Layer
Many older heaters are not flame resistant. The exterior may also become very hot to the touch, resulting in burns. Newer models are designed to higher safety standards. Most of them have a fireproof outside layer that does not overheat.
While a quiet fan can be nice, it can be hazardous. Someone may not know that it is running; therefore, it could end up staying on for a longer period of time than it should. Quiet fans are especially dangerous when children are around the area and the parent doesn't known that the fan is on because a child could easily get his or her finger stuck or injured inside the fan. The fan could also be hot to the touch, which could cause the child to get burned as well.
Window fans are sometimes unstable. They can easily fall out of the window when not placed correctly. If you live in an area with high pollution or high humidity, window fans are probably not your best choice since they move the air from outside into your house. If these fans are not inserted into the window correctly, bugs and small animals could come through the small openings around your fan and window. Make sure there's a tight seal around your window fan.
