What is the typical voltage range for residential electric heaters?

Residential electric heaters typically operate within a voltage range of 120 to 240 volts. This range caters to standard household electrical systems and is designed to accommodate the common circuits used in residential buildings.

Most residential amenities, such as water heaters, space heaters, and baseboard heating systems, are engineered to function optimally within this voltage range. Electric heating devices that use 120 volts are generally suitable for smaller appliances, while those that operate at 240 volts are often employed for more substantial heating needs, such as larger space heaters or electric furnaces.

Higher voltage options, like those found in the other choices, are more commonly associated with industrial or commercial applications where larger systems requiring more power are employed. These systems typically exceed what is necessary or safe for residential use, making them unsuitable for normal household heating needs. Thus, the 120 to 240 volts range is the standard for residential electric heaters.
