Abstract
A valve assembly for providing hot water includes a hot water side with a hot water inlet and a cold water side. The valve assembly also includes a central channel for fluid communication between the cold water side and the hot water side and a bypass valve portion. The bypass valve portion includes a thermostatic valve adapted to substantially block the fluid communication through the central channel between the cold water side and the hot water side when a temperature of water flowing through the central channel increases above a threshold temperature. The bypass valve portion also includes a temperature adjustment portion adapted to selectively vary the threshold temperature.
