Abstract
A hot water humidifier with an automatic siphon drain fed with cooler source water is flushed via a drain. The humidifier includes the humidifier tank and an inverted U-shaped siphon conduit having one end coupled to the tank and the other end coupled to the drain. A valve controlling the cooler source water feeds the water into the tank to maintain the temperature of an admixture of cooler source water and any preexisting tank water at or below a predetermined temperature during a flush cycle. The tank is flushed and drained via the automatic siphon based upon the level of the admixture in the tank and the level of admixture in the siphon. The source water may be coupled to the humidifier tank via the siphon conduit such that cooler source water may be added during the siphoning action. A method of flushing a hot water humidifier is also included.
