An aerosol-generating device is provided, including a housing including a first tubular section to receive a combustible heat source and a second tubular section to receive an aerosol-generating substrate; a heat-conductive element between the sections to transfer heat received in the first section to the substrate received in the second section, the element including a bimetallic element having first and second portions; and a heat-insulative sleeve around at least a portion of the second section including one or more air inlets, the bimetallic element arranged to deform from a first position where a first portion of the bimetallic element is proximate the first section and a second portion of the bimetallic element is proximate the second section, to a second position where the first portion of the bimetallic element is displaced away from the first section towards the second section, when the bimetallic element is heated above a threshold temperature.
