When it comes to heating outdoor spaces, we rely on two main types of heaters, both of which utilize infrared technology.
Infrared heat, a part of the electromagnetic spectrum, is emitted by all objects. However, the nature of the electromagnetic wave varies depending on the object's temperature. Objects with higher temperatures emit a more intense form of infrared heat, which feels hotter on the skin but is less easily absorbed by our bodies. This is known as short-wave infrared heat. On the other hand, objects with lower temperatures emit a less intense form of infrared heat, which can penetrate more deeply and provide a more thorough warmth. Infrared heaters leverage these different types of infrared to offer heating levels suitable for a wide range of applications.
Long-Wave Infrared Outdoor Heaters
Long-wave infrared heat is produced by infrared panels that can reach temperatures of up to 100˚C. This type of heat is highly efficient for indoor or enclosed locations (balconies, terraces
etc.) as our bodies readily absorb it, ensuring lasting comfort for hours on end. Long-wave infrared heat is actually the same form of infrared that we naturally emit, making it a natural and soothing source of warmth. It is no wonder that this type of heat is also utilized in neonatal incubators and health spas and retreats for relaxation purposes.
Short-Wave Infrared Outdoor Heaters
In contrast, outdoor heaters can reach temperatures of up to 1500˚C and emit short-wave infrared heat, accompanied by an orange glow. This intense heat is perfect for exposed outdoor locations where the warmth from a long-wave infrared heater would not be sufficient. Short-wave infrared heaters provide instant warmth, making them ideal for patios, pub gardens, alfresco dining areas, and workstations that are periodically used and require a quick burst of intense heat. However, it is worth noting that prolonged exposure to this intense heat can become uncomfortable.
In conclusion, understanding the different types of infrared heat and their applications is crucial in selecting the perfect outdoor heater. Long-wave infrared heat offers efficient and comfortable warmth for enclosed patios, terraces and balconies when short wave will be ideal for open space.
