An aerosol-generating system (includes a cartridge, a liquid aerosol-forming substrate, and an aerosol-generating device. The cartridge includes a cartridge housing and a solid aerosol-forming substrate. The aerosol-generating device includes a cavity configured to receive at least a portion of the cartridge, an airflow inlet, and an airflow sensor. The airflow sensor is in fluid communication with the airflow inlet and the cavity). The aerosol-generating device includes a bypass air inlet in fluid communication with the cavity, an electric heater configured to heat the liquid aerosol-forming substrate, a power supply, and a controller. The aerosol-generating system is configured so that the cartridge housing substantially prevents airflow through the bypass air inlet when the cartridge is received within the cavity.

The method includes first defining at least one channel within a first housing of a heater assembly, the at least one channel extending from a first end to a second end of the first housing, second defining a cavity in the first end of the first housing, third defining a first reservoir in the second end of the first housing, the at least one channel being in fluid communication with the first reservoir, and fourth defining an opening within a first wall within the first housing, the opening causing the first reservoir and the cavity to be in communication with each other.
