A radiant heater is a type of heating device that warms up a space by emitting infrared radiation. This radiation directly heats objects and people in the room rather than warming the air, making it an efficient option for quick heating. Radiant heaters are commonly used in homes, garages, and outdoor spaces. These heaters come in various forms, including electric, gas, and propane models. They can be portable or fixed installations, allowing for flexibility in heating different areas. Radiant heaters are often favored for their ability to provide immediate warmth and their energy efficiency compared to traditional heating systems.
