Abstract
A humidification system for a building utilizing a hot water heating tank within which is mounted a plenum chamber. Hot water from the tank is directed into the plenum chamber in controlled quantities and is agitated as controlled by a humidistat within the building to either vaporize the water within the plenum chamber or to force pressurized air through the plenum chamber to wet the air. The vaporized water or the wet air is directed from the plenum chamber into the air supply of the building. A water level control in the form of a float valve maintains the level of the water within the plenum chamber at a controlled level. The water may be vaporized by an electrical heater within the plenum chamber or the water may be aerated by air forced through the plenum chamber by a compressor, the humidistat activating the heater or the compressor.
