Two heat exchangers are arranged in a fixture body of a water dispenser. A Peltier arrangement is provided between the two heat exchangers. Valves arranged downstream of the two heat exchangers with respect to the direction of water flow control the flow of hot and cold water through the water dispenser. The Peltier arrangement senses and responds to the temperature difference prevailing between the two heat exchangers through which respectively flows hot water and cold water. This Peltier arrangement converts the sensed temperature difference into an electrical potential or voltage which is used to power an electronic control. This electronic control, among other things, influences opening and closing of the valves.
