ABSTRACT:
Heat in the hot water lines of a water system is automatically recovered by providing a bridge conduit between the cold water lines and the hot water lines and by depressurizing the hot water lines relative to the cold water lines thereby to automatically direct higher pressure cold water into the hot water lines through the interconnection, which preferably is located near the hot water outlet. The higher pressure cold water forces the hot water back into the storage tank and out of the hot water lines until pressure is equalized. Loss of unused heat trapped in the hot water lines is minimized thereby saving energy.
