Line volt heating is a type of heating system that uses line voltage, or the voltage that is delivered to a home from the power grid, to generate heat. Line volt heating systems are typically used in residential and commercial buildings, and can be found in a variety of applications such as baseboard heaters, wall heaters, and ceiling-mounted heaters. Line volt heating systems are a popular choice because they are relatively inexpensive to install and operate, and they provide efficient, consistent heat. Line volt heating systems are also relatively safe, as they are designed to shut off if the voltage drops too low or if the temperature gets too high. The primary disadvantage of line volt heating systems is that they can be noisy, as the motors and fans used to generate the heat can be quite loud.
