Heat lamps are wired into the house just like any other light fixture. It is recommended to hire an electrician since there is a lot of moisture in a bathroom.
Heat lamps are great for knocking the chill out of a bathroom during the winter months. The size of the room and the main use of the lamp can determine which model is most beneficial. Some lamps are louder than others, and some can produce more heat. Generally, a heat lamp is placed in the ceiling of the bathroom and wired into the house's circuits. This can be done by the homeowner, but a lot of precautions should be taken when working around water. A professional electrician is the best option to have the lamp installed.
