An ice piece release system that includes a chilled compartment set at a temperature below 0° C., a warm section at a temperature above 0° C., and a tray in thermal communication with the chilled compartment. The tray includes a plurality of ice piece-forming receptacles and a cavity in thermal communication with the receptacles. The ice piece release system also includes a primary reservoir assembly in thermal communication with the warm section and fluid communication with the cavity of the tray. The ice piece release system further includes a heat-exchanging fluid having a freezing point below that of water, and the fluid resides in the primary reservoir assembly and the cavity of the tray. The primary reservoir assembly is further adapted to move at least a portion of the heat-exchanging fluid in the reservoir assembly into the cavity.
