A compact fuel fired steam generating type humidifier. The apparatus uses a gaseous fuel as the prime source of heat to generate steam used to humidify air in the heating, ventilation and air conditioning of buildings. The humidifier may be a stand alone unit that disperses the steam into the space or the steam generated by the apparatus may be dispersed in forced air flow of the building heating system. The steam generating unit includes a water tank in which there is located a combustion chamber and a heat exchanger chamber for transferring the heat from the products of combustion to the water.
