Disclosed is a portable radiant heating device that has a base, a radiant heat source mounted in a tiltable reflector, and a safety interlock device located in the base. The safety interlock uses a pressure-sensitive foot that prevents the heater from producing infrared heat when not in contact with a mounting surface. The safety interlock device also prevents the heater from producing infrared heat when the reflector is not tilted so as to prevent excessive amounts of infrared heat from being directed towards the mounting surface.
