A heated humidifier for an infant incubator wherein the water in the water reservoir is heated by an active heater located above the surface of the water and a heat exchanger that transfers heat from the active heater and which extends downwardly to a point beneath the water surface to heat the water. In the preferred embodiment, the heat exchanger is an extruded member in the shape of an I-beam to transfer the heat from an electric heater above the surface of the water to heat the volume of water in the reservoir to create water vapor.
