The invention relates to an aerosol-generating system (10) comprising a first air inlet (22) and an air outlet (24). The aerosol-generating system may further comprise a liquid storage portion (40). The liquid storage portion may hold a liquid aerosol-forming substrate. The liquid storage portion may have a liquid outlet (42). The aerosol-generating system may further comprise an airflow passage from the first air inlet to the air outlet past the liquid outlet. The aerosol-generating system may further comprise a wick (26). The wick may be provided in the airflow passage. The wick may be arranged to receive liquid from the liquid storage portion in response to a pressure drop in the airflow passage at the liquid outlet. The aerosol-generating system may further comprise a first heating element (28) positioned to heat the liquid in the wick. The wick may be arranged at a distance from the liquid outlet.
