In a hot and cold water plumbing installation, a volume of hot water is first drawn from the hot water line and stored in an insulated reservoir. When the temperature of the water near the most distal location of the hot water line falls below a predetermined level, the contents of the insulated reservoir are reinjected back into that line to flush the cooled down water back into the water heater. A second reservoir is used between the water heater inlet and the cold water source to absorb the excess water resulting from the aforesaid reinjection and prevent hot water from being injected into the cold water line.

[ What is claimed is:] [1.] In a hot and cold water distribution system wherein hot water having a cold water inlet and a hot water outlet is distally delivered through a hot water line from a water heater to at least one hot water faucet, and cold water is delivered through a first cold water line to said water heater and through a second cold water line to at least one cold water faucet proximate said hot water faucet, an improvement for maintaining high temperature in the water drawable through said hot water faucet, said improvement comprising:means for storing a volume of hot water drawn from said hot water line;means for injecting said stored volume back into said hot water line when water temperature in said hot water line drops down to a preset level; andmeans for storing a compensating amount of water from said water heater as said volume is injected into said hot water line; andmeans for returning said amount back into said water heater as said volume is drawn from said hot water line.
