1. A cartridge for an aerosol-generating system, the cartridge comprising:
a liquid storage portion comprising a housing with a first opening, the housing configured to contain a liquid aerosol-forming substrate;
a capillary material having first and second faces; and
a heater assembly comprising
an electrically insulating support having a second opening,
an electrical heating element supported by the electrically insulating support and being configured to heat the liquid aerosol-forming substrate to form an aerosol, and
first and second electrically conductive contact portions disposed at opposite sides of the second opening and being configured to connect to electrical connectors of a battery configured to supply power to the heater assembly,
wherein the heater assembly is connected to the housing of the liquid storage portion, and
wherein the first face of the capillary material is in physical contact with the electrical heating element and the second face of the capillary material is opposite the first face of the capillary material, the capillary material being configured to convey the liquid aerosol-forming substrate to the electrical heating element by capillary action.
