4 | Heat is much healthier than with convection heating. Indeed, the air displacement is much more limited. The dust is not burned and then conveyed into the air, as in contact with a convector. Also, the air can be refreshed (open the windows for 5 min) without losing all the benefit of heating because the energy is stored in the structure of the building (wall, floor, ceiling, etc.) and not only in the air. Finally, infrared regulates the humidity level of the air without drying it out. Infrared heating is therefore recommended for people with allergies or asthma.
