Device for delivering hot water comprising a hot water tank (1) in which a thermostatically controlled heating unit (3) is provided, a syphon (4) for the removal of hot water, the inlet opening of which syphon is situated at a first level (5), a cold water inlet pipe (6) in which a shut-off valve (7

Device for delivering hot water comprising a hot water tank (1) in which a thermostatically controlled heating unit (3) is provided, a syphon (4) for the removal of hot water, the inlet opening of which syphon is situated at a first level (5), a cold water inlet pipe (6) in which a shut-off valve (7) controlled by a control unit (8) is provided, and a level probe (10) at a second level (9) above the highest point of the syphon. After the opening of the shut-off valve in response to a start signal the level probe (10) detects when the rising surface of the water has reached the second level and then delivers a signal to the control unit in order to close the shut-off valve. A second level probe at a third level above the first level but below the second level, provides an “open”signal to the shut-off valve unless the presettable end setting of a counter, counting the number of generated “open”signals, has been reached.

An apparatus for delivering hot water, comprising: (a) a water tank; (b) a thermostatically controlled heating unit installed at a relatively low level within said water tank; (c) a syphonic tube for discharging hot water from the tank, said tube being installed in a sidewall of said tank, whereby a

An apparatus for delivering hot water, comprising: (a) a water tank; (b) a thermostatically controlled heating unit installed at a relatively low level within said water tank; (c) a syphonic tube for discharging hot water from the tank, said tube being installed in a sidewall of said tank, whereby an inside end of said tube is at a level above the heating unit; (d) a cold water inlet pipe connected to the tank at a level underneath said heating unit; (e) a shut-off valve, installed in the cold water inlet pipe and controlled by a control unit; (f) two water level detecting probes, the first probe being positioned at a first level above the inside end of the syphonic tube and the second probe being positioned at a second level above the inside end of the syphonic tube but below the first level, wherein said first probe delivers a signal to the control unit which in response closes the shut-off valve as soon as the water reaches the first level, and said second probe delivers a signal to the control unit as soon as the water reaches the second level; and (g) a start means to provide a start signal to the control unit which in response opens the shut-off valve, wherein said control unit comprises a counter, which is presettable to a predetermined end setting and advances by one step from an initial setting every time a signal is received from said first probe and generates a signal to open the shut-off valve as the signal from the second probe is received unless said presettable end setting of the counter has been reached.
