1. An apparatus for heating aerosol generating material to volatilize at least one component of the aerosol generating material, the apparatus comprising:
a housing comprising a heater, the heater comprising a first heating surface, wherein the first heating surface is adapted to contact at least a major portion of a heat conductive planar flexible base of a first body of a cartridge that is insertable into the housing, whereby in use, the heater heats aerosol generating material in a chamber defined by the first body to volatilize at least one component of the aerosol generating material,
wherein the apparatus further comprises a second heating surface for contacting at least a major portion of the heat conductive planar flexible base of a second body of the cartridge that is insertable into the housing, whereby in use, the heater also heats aerosol generating material in a chamber defined by the second body to volatilize at least one component of the aerosol generating material,
wherein the heater comprises an elongate plate extending parallel to a longitudinal axis of the apparatus, said first and second heating surfaces being formed on opposite sides of said elongate plate,
wherein said first heating surface has a convex curvature that extends towards the heat conductive planar flexible base of said first body of a cartridge that is insertable into the housing, such that the planar flexible base of said first body is deformed to adapt to the shape of the convex curvature of the first heating surface, and
wherein the second heating surface has a convex curvature that extends towards the heat conductive planar flexible base of said second body of a cartridge that is insertable into the housing, such that the planar flexible base of the second body is deformed to adapt to the shape of the convex curvature of the second heating surface.
