A boiling water dispenser includes a hot water reservoir, a user-actuated faucet for drawing boiling water from a discharge zone at the top of the reservoir, and a solenoid-actuated valve for admitting unheated water to an inlet zone at the bottom of the reservoir. An electric resistance heating element within the reservoir is supplied with AC current through a series- connected bilateral switch device which is periodically switched on and off in response to the sensing of steam in a reservoir venting conduit to maintain the dispensing temperature at the boiling point. An indicator lamp conditioned by a sensor in the reservoir confirms to the user that the dispensing temperature is at the boiling point.

A boiling water dispensing apparatus comprising: a hot water reservoir; means including a reservoir heating element within said reservoir operable from an applied electric current for heating water in said reservoir; inlet means for admitting cold water into said reservoir; outlet means for discharging heated water from said reservoir; steam detection means responsive to the presence of boiling water in said reservoir for producing a control signal indicative thereof, said steam detection means being generally thermally isolated from said hot water reservoir for preventing the temperature of the reservoir from affecting the steam detection means; and temperature regulating means responsive to said control signal for controlling the application of electrical current to said resistance means to maintain water in said reservoir substantially at actual boiling temperature.
