Abstract: A manifold system for distributing fluid from a single source to multiple locations is shown and described. The manifold system receives a single source of a fluid, such as water, which then is used for multiple purposes. The manifold system has an outlet structure to the provide water at a desired pressure to the pressure vessel for make-up feedwater, a structure that includes a mixer that provides hot water at a desired temperature range, an outlet structure that provides water at a predetermined pressure to water heating system, which may include a heating coil that provides an input to the mixer, and an outlet structure that includes a safety device that monitors the pressure in the manifold. The mixer receives as an input the hot water from the outlet of the heating coil. The hot water from the heating coil is mixed with cold water from within the manifold in the correct proportions to produce hot water within a desired temperature range.
