An aerosol-generating system includes a cartridge and an aerosol-generating device. The cartridge includes a cartridge housing, a first aerosol-forming substrate in the cartridge housing and a second aerosol-forming substrate in the cartridge housing. The aerosol-generating device defines a cavity configured to receive at least a portion of the cartridge along a first direction and the aerosol-generating device includes a transfer element extending from an end wall of the cavity, the transfer element having a longitudinal axis extending substantially parallel to the first direction, the transfer element contacts the second aerosol-forming substrate when the portion of the cartridge is in the cavity, an electric heater including a resistive heating coil wrapped around a portion of the transfer element, the resistive heating coil being wrapped around the longitudinal axis of the transfer element, a power supply, and a controller configured to control a supply of electrical power from the power supply to the electric heater.
