Far infrared

[7] Though multiple applications of long wave or FIR heating exist, a common representation comprises radiant panel heaters.

[9] Owing to their size and flexibility,[10] infrared panel heaters can be fitted on walls and ceilings for added-space saving benefits.

Electric FIR panel heaters are shown to have up to 98.5% efficiency from supply to production of heat with satisfactory thermal comfort, thermostatic control, and with low initial investment.

In the field of biomedicine, experiments have been conducted using fabrics woven with FIR-emitting ceramics embedded in their fibers.

[13] The researchers have suggested that the emission of far-infrared radiation by these ceramics (referred to as cFIR) could facilitate cellular repair.
