Abstract

A re-circulating hot water system adapted for supply and space heating applications having a first re-circulating flow mode of operation and a second demand flow mode of operation and comprising a source of hot water, a hot water outlet and a duplex header connecting the source of hot water to the hot water outlet. The duplex header has a central fluid flow passage and an annular fluid flow passage. Flow from the source of hot water is directed into the system by way of the central fluid flow passage. Return counter-flow is directed back to the hot water source by way of the annular fluid flow passage. The header transports hot water from source of hot water to the outlet by duplex connecting conduits. There is also a source of replenishment water that is isolated from the system during the re-circulation mode and connected to the system during the demand mode to replenish consumed water. The duplex header re-circulates hot water between the outlet and the source of hot water thereby keeping the system temperature at a desired value. In the demand flow mode of operation there is hot water available at the outlet instantaneously.
