ABSTRACT:
A hot air furnace humidifier has a heat chamber and a duct connecting the chamber to a furnace. The chamber has a water retaining vessel, preferable provided with a disposable liner. A pair of level sensors register the minimum and maximum water level within the vessel. The water level sensors can be either in proximity with the water or submerged within the water. A heating element incorporates a heat sensing device and can be provided with a thermostat and in proximity with the water or submerged. A water refill pipe is provided with an on/off device and automatically refills the vessel in response to the electronic controls. The electronic controls are connected to the water level sensors, heating element and water refill pipe. The controls can include a humidistat and/or be incorporated with the furnace controls. The electronic controls control the water level based on information received from the water level sensors and the temperature based on information received from the heating element, thereby providing constant evaporation within the heat chamber.
