-0- HOT AIR HEATING SYSTEM Abstract of the Disclosure A hot air heating sytem utilizing the otherwise wasted heat and moisture in the gases of combustion to pre-heat and humidify the room air. The hot flue gases discharged from the furnace are mechanically induced by a blower to pass through an auxiliary heat exchanger in countercurrent flow to the cold air being returned from the rooms to the furnace, thereby pre- heating the return air and cooling the exhaust combus- tion gases. The products of combustion include a con- siderable quantity of water vapor. Cooling these gases results in condensation of this water, which is then collected in a sump and utilized to humidify the room air. Condensation of the vapors releases their latent heat of vaporization adding considerably to the heat recovery of the system. Because the water does not contain any minerals the humidifier does not have the usual problems of mineral deposit build-up.
