Claim 0:
1. An electrically heatable aerosol-generating system configured to receive an aerosol-forming article, the system comprising:
a tubular housing having a longitudinal direction and an opening at one longitudinal end configured to removably receive the aerosol-forming article;
a cylindrical heater element comprising a substantially circular end face, the cylindrical heater element being disposed proximate a longitudinal end of the tubular housing;
a supply of electrical energy connected to the cylindrical heater element and configured to resistively heat the cylindrical heater element when the system is activated;
an opposite longitudinal end having the opening, so that the substantially circular end face of the cylindrical heater element is proximate a longitudinal end of the aerosol-forming article when the aerosol-forming article is inserted into the tubular housing; and
an annular thermally conductive element disposed on an inner surface of the tubular housing and comprising a first portion connected to the cylindrical heater element and a second portion configured to contact the aerosol-forming article when the aerosol-forming article is inserted into the tubular housing,
a thermally insulating material provided between the heater element and an outer housing forming the tubular housing,
wherein the system is configured to supply a first amount of electrical energy to the cylindrical heater element to heat the cylindrical heater element to a first temperature, and to supply a second amount of electrical energy to the cylindrical heater element to maintain the cylindrical heater element at a second temperature,
wherein the second temperature is lower than the first temperature, and
wherein a difference between the first temperature and the second temperature is at least 100 degrees Celsius.
