An infant warmer includes an infant enclosure defining an infant compartment, and a heating system pneumatically coupled with the infant compartment. The heating system includes a heater configured to selectively transfer heat to the infant compartment, and a thermal storage device configured to store heat from the heater and to selectively transfer said stored heat to the infant compartment. The infant warmer also includes a controller operatively connected to the heating system. The controller is configured to regulate the transfer of heat from the thermal storage device such that a target temperature is maintained within the infant compartment.
