How Energy Efficient are Infrared Radiant Heaters? While this can be effective in a closed space (indoors), this air will generally escape into the environment before resulting in any appreciable impact on the people in outdoor spaces – the result being ineffective heating at a high cost. In comparison convective heaters indirectly heat people in a space by first warming the air in that space. Infrared radiation is emitted from infrared heaters which transmit infrared radiant energy through the air and is absorbed by objects that it encounters, making its molecules vibrate thereby, directly increasing the heat of the object. Is there Better Heat Coverage with an Infrared Radiant Heater?
Since infrared heaters (or radiant heaters) are heating objects, not air, they are able to effectively heat outdoor spaces, unlike convection heaters which have little to no impact on an outdoor area.
