A hot water dispenser includes a hot water reservoir, a user-actuated faucet for drawing hot water from an outlet zone near 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 inline flow regulator establishes an inlet flow rate less than the faucet flow rate to maximize the volume of hot water available at the faucet. 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 accordance with the temperature of water sensed by a sensor at the faucet to maintain a constant dispensing temperature. The switch device is thermally coupled to the bottom of the reservoir such that the reservoir acts as a heat sink to dissipate heat generated during switching. An indicator lamp conditioned by the sensor confirms to the user that the dispensing temperature is within a predetermined range.

A hot water dispensing apparatus comprising: a hot water reservoir; means including a resistance 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; said inlet means including flow regulating means for controllably admitting water to said reservoir at a first predetermined flow rate and said outlet means controllably discharging water from said reservoir at a second predetermined flow rate, said first predetermined flow rate being less than said second predetermined flow rate; temperature regulating means responsive to the temperature of water in said reservoir for controlling the application of electric current to said resistance heating element to maintain the water in said reservoir at a substantially constant predetermined temperature; said regulating means including a current switching device in series-circuit relationship with said resistance heating element; said current switching device in operation generating heat; and means for thermally coupling said current switching to said reservoir whereby heat generated in the operation of said device is transferred to said reservoir.
