An electric radiant heater, also known in Iran as a radiant electric heating system, is a device that uses single-phase household electricity to provide heat. This type of radiant heater works by heating elements within it. Once the elements reach temperature, the heat is emitted as infrared waves, which are then distributed into the surrounding environment by a thermal umbrella. An electric radiant heater is considered a very suitable option for heating open spaces, residential areas, and villas, particularly in locations where access to gas is not available. These radiant heaters are produced in various capacities and are recognized in Iran by the name “Garmatab Barghi.”
Since electricity is the energy source for an electric radiant heater, there is no need to install a chimney. One of the significant advantages of this system is the absence of pollution resulting from combustion and its byproducts, meaning these heaters have very low contamination levels. Furthermore, you only need standard single-phase household electricity to use this heating system.

An electric radiant heater, also known in Iran as a radiant electric heating system, is designed to provide a natural sense of warmth and often features an attractive, aesthetic design. Infrared electric radiant heaters are manufactured using special technology. The use of a specific aluminum alloy in the radiant panels, a precise coating process, and the careful placement of heating elements ensure that after the device is turned on, heat is quickly transferred to objects and people.
This type of heating system is known as a Radiant Heater or Garmatab Barghi (Electric Radiant Heater) and is based on the principles of radiant heat transfer. The design of electric radiant heaters is inspired by the sun’s natural heating process; they are responsible for transferring radiant heat to objects. In nature, radiant waves from the sun travel through space and convert into heat upon hitting the Earth’s surface. A key characteristic of this type of heat is that radiant waves transfer their energy only upon contact with objects, rather than by heating the air. Consequently, heat loss in an electric radiant heater is very low, providing desirable and uniform warmth with optimal energy consumption.
While most electric radiant heaters available on the market are designed for domestic use and are typically employed in closed spaces or small open areas, in Iran, these devices are known as industrial electric radiant heaters (“Garmatab Barghi Sanati”). However, when the need arises to heat larger spaces such as an open courtyard or an industrial hall, particularly in locations where gas installation is not feasible, an industrial electric radiant heater is the appropriate choice. These devices are also used in restaurants to heat outdoor seating areas and are sometimes referred to as restaurant electric radiant heaters (“Garmatab Restorani Barghi”). These units feature higher power and greater radiant output, enabling them to effectively heat larger areas.
While the appearance of these devices might not be as aesthetically refined as domestic heaters, they are well-suited for industrial applications or open restaurant environments. These heaters are equipped with two two-meter heating element lamps. The rapid speed of radiant heating provided by an electric radiant heater is one of their key advantages.
