Abstract: A novel device for vaporizing of phyto material is disclosed. The device includes a housing and a heating chamber, wherein the heating chamber is for receiving of phyto material, in first and second phyto material portions. The heating chamber includes a centrally located first heater element disposed on a first substrate and a second heater element disposed on the first substrate, the heater elements for outwardly radiating heat through the phyto material, where at least one of the heating elements is enabled and a user inhales vapor from an inhalation aperture in fluid communication with the heating chamber. An airflow processing member restricts a flow of ambient air into the heating chamber. The first heater element is for heating the first phyto material portion and the second heater element is for heating of the second phyto material portion.
