Which type of heating system utilizes resistance heating elements?

An electric furnace utilizes resistance heating elements to generate heat. In this type of system, electrical current passes through these resistance elements, converting electrical energy into heat energy. The heat produced is then distributed throughout the space being heated, typically via a system of ducts or directly into the living area.

Resistance heating is a common process in electric heating systems, where the resistance of the heating element converts electrical energy into thermal energy efficiently. This principle is the foundational technology for electric furnaces, allowing them to provide effective and uniform heat output to spaces, especially in areas where gas or other fuel sources may not be as readily available.

The other heating systems mentioned do not operate based on resistance heating elements; gas furnaces rely on combustion for heat, heat pumps transfer heat from one place to another rather than generate it directly through resistance, and hydronic systems circulate hot water to provide heating.
