A water heater system for a water dispensing fountain having a refrigerated water reservoir, is disclosed. The water heater system is comprised of a plastic molded hot water tank formed in a support membrane. A feed conduit is also formed in the membrane and extends from a connector, which secures to the bottom wall of the refrigerated water reservoir, to the bottom end of a serpentine array of the conduit which extends upwardly to the bottom wall of the hot water tank. The purpose of the serpentine conduit is to prevent hot water from the tank from flowing back into the refrigerated water reservoir. A dispensing conduit extends from the hot water tank and is located at a position whereby water can be extracted from a valve connected thereto by gravity flow. An exhaust pipe also extends from the hot water tank and is provided with an exhaust port located above the top water level of the refrigerated water reservoir whereby to exhaust water pressure vapors from the hot water tank.
