Abstract
Systems and methods for radiative heat transfer are disclosed. In an exemplary embodiment, an infrared heater comprises infrared heating elements and a controller. The infrared heating elements correspond to respective heating zones. The controller causes the infrared heating elements to turn on at different time in succession such that respective heating zones are radiatively heated at different times. In some instances, the respective heating zones correspond to different heating zones of a user, and the user feels a heating wave effect as the infrared heating elements are turned on and off at different times.
