Electric Heating Unit

An electric heating unit, or an electric unit heater, is designed to warm up spaces and is available in various types suitable for a range of applications. The method of transforming electrical energy to heat energy is called electric heating. An electric heater converts electric currents to heat using an electrical resistor (heating element).
