Electromagnetic infra-red radiation transfers heat... WebHeat radiation is a unique case of heat transfer from the heat source to a body, as it travels via electromagnetic waves. The body can be located near the source or at a far distance, and still, experience the effects of heat radiation. Considering heat radiation doesn't rely on the matter to propagate, it can travel in a vacuum as well.
