What is Far infrared (FIR) Energy?
Far infrared (FIR) energy is a type of heat energy that comes from a specific part of the electromagnetic spectrum. It is called "infrared" because it sits just below the visible light spectrum in terms of wavelength.
Infrared energy is divided into three categories: near, mid, and far infrared, based on their wavelengths. Far infrared has the longest wavelength, which ranges from about 15 microns to 1,000 microns.
In relation to heating, FIR works differently from traditional convection heaters (which heats the air).
Instead, far infrared heating uses electromagnetic waves to directly heat objects and people in the room, much like how sunlight warms your skin on a cool day.
These waves penetrate surfaces (like your body, walls, or furniture) without needing to heat the air first. The objects then slowly release that heat, maintaining warmth in the room even after the heater is turned off.
This method of heating has several benefits:
Energy efficiency: Because it heats objects rather than air, far infrared systems require less energy to achieve the same comfort level, making it more efficient.
Even warmth: Unlike convection heating, which can create cold spots due to uneven air distribution, FIR provides consistent warmth across the room.
Health benefits: FIR is also claimed to have health benefits, such as improving circulation and helping with muscle recovery.
Since far infrared heaters do not rely on blowing warm air, they do not circulate dust or allergens, making them ideal for people with respiratory issues. Overall, FIR is a comfortable, energy-efficient alternative to traditional heating methods.
