An electric furnace is a heating system that uses electricity to generate heat for residential or commercial spaces. It operates by passing electric current through heating elements, which then warm the air that is circulated throughout the building. Electric furnaces are known for their efficiency and ability to provide consistent heating. These furnaces are often used in areas where natural gas is not available or where electric heating is preferred for safety or environmental reasons. They can be integrated with thermostats for temperature control and are generally easier to install compared to gas furnaces.
