An infant warming apparatus that functions both as an infant incubator as well as an infant warmer. The apparatus has a heater that moves vertically with respect to an infant support during the change in function between an infant incubator and infant warmer. A powered motive system, such as an electric motor, powers the movement of the heater between its upper and its lower positions. The heater also has a door or doors that are open when the heater is at or neari ng the upper position so that the heater can direct energy toward the infant to war m the infant when acting as an infant warmer. The doors close at or shortly after the heater commences movement to the lower position. When closed, the doors isolate the heater to prevent the inadvertent touching of the heater by the infant or attending personnel and prevents the further radiating of infrared energy towards the infant. The mechanism operates automatically without any reminder to the user or action by the user. Preferably the actual opening and closing of the doors takes place within a short distance from the upper position, more preferable within about 6-8 inches form the upper position. A vent is also provided in the heater housing that ventilates the housing when the heater is in its upper position and closes to confine the housing when the heater is in its lower position. A mechanism automatically closes the vent when the heater moves from its upper position to its lower position and opens the vent when the heater moves from its lower position to its upper position. In the preferred embodiment, the vent is biased towards its open position and the doors are biased towards their open positions.
