  • Patent number: 4077545
    Abstract: An instant hot water dispenser system utilizes the same spout to dispense instant hot water as is used to dispense water from the plumbing system of the building and mixtures thereof. The instant hot water dispenser utilizes a small electrically heated hot water tank located adjacent to the faucet and includes a faucet spout having an inside passage for dispensing instant hot water and an outer passage for dispensing plumbing system water. The outer water passage provides an insulating water jacket surrounding the instant hot water passage to prevent high temperatures of the spout surface and eliminate the possibility of burns to the user. Various valving arrangements are disclosed to dispense through the spout plumbing system water only, instant hot water only, a mixture of instant hot water and plumbing system water, etc.
